Four others focus on hair, skin and nails without a sleep angle, and here is when each one wins. - Author: Tanner Torres - Tags: Health & Wellness, Hair Care, Supplements The best hair vitamins for sleep in this shortlist is Angry Supplements Hair Envy PM, a 60-capsule nighttime formula the brand says delivers 3mg of melatonin per serving alongside biotin, calcium and magnesium. If you already sleep well and just want a beauty complex, NUTRAHARMONY's 60-count biotin, collagen, keratin and hyaluronic acid capsules are the stronger pick. Four of the five products here are daytime hair, skin and nail formulas, so the sleep angle narrows the field quickly. In this guide 1.

Only one item in this set makes any sleep claim in its listing: the Angry Supplements PM formula. Every other product is a straight hair, skin and nails complex sold in the biotin category. That distinction matters, because a shopper searching for the sleep angle will otherwise buy a daytime supplement and get no wind-down effect. That does not make the four daytime formulas wrong choices. It means the sleep decision splits neatly: - If you want the melatonin and biotin combined in one capsule, there is exactly one product here that promises it. - If you already sleep well and only want the hair benefit, the four beauty complexes compete on ingredient list, capsule count and price band, and you can safely ignore the sleep framing. One consideration the listings will not resolve for you: melatonin is not right for everyone, and doses vary. The Angry Supplements listing says 3mg per serving with 1.5mg per capsule, so a person who wants to start lower can take one capsule instead of two. Anyone on prescription medication or with a sleep condition should ask a doctor before adding melatonin to a routine, regardless of what any label promises. ## How I screened this shortlist I compared the five listings side by side on three axes: whether the product actually addresses sleep in its own copy, what the beauty ingredients look like beyond biotin, and how many days one bottle covers. The disqualifiers were narrow. Two capsule counts were cross-checked against the stated daily serving so a reader could plan how often to reorder. Feature bullets were logged as brand claims, not measured facts. Three specific reasons picks dropped down the order rather than out of it: 1. **No sleep ingredient in the listing.** Four of the five products do not mention melatonin, magnesium for relaxation, or any nighttime claim. They are fine hair vitamins; they are not the answer to the sleep query. 2. **Thin published specifications.** The Micro Ingredients bottle lists only a size, which is unusual for a 400-count softgel. That is not a reason to avoid it, but it left me with less to compare against. 3. **A category path that hides the intent.** Only the Angry Supplements product sits under Sleep Supplements. The others sit under B7 (Biotin), which tells you what a shopper searching by category would actually see. What survived is a set that lets one buyer profile pick a nighttime formula and four other buyers pick a daytime one without wading through the wrong shelf. ## 1\. Angry Supplements Hair Envy PM — Best overall **The only product in this set that pairs a hair, skin and nails complex with a melatonin sleep claim, which is exactly what the keyword asks for.** [![Angry Supplements Hair Envy PM 60-capsule bottle — the only pick in the set with a stated melatonin dose](https://m.media-amazon.com/images/I/417e42XtpPL._SL500_.jpg)](https://www.amazon.com/dp/B0FBCF9FMW?tag=mundocisco-20) **Best for:** women who want a single nightly capsule that pairs biotin with a melatonin wind-down **Skip it if:** you already take a separate sleep aid or avoid melatonin entirely Angry Supplements says the PM formula delivers 3mg of melatonin per serving, split as 1.5mg per capsule, alongside biotin, calcium and magnesium in a 60-capsule bottle. That split-dose design is the practical detail here. A shopper who wants to start low can take one capsule at bedtime rather than commit to the full serving on night one, and step up once they know how they respond. Magnesium is included as a relaxation nutrient, per the listing. Within this set, it is also the only product that sits in the Sleep Supplements category path rather than the biotin shelf, which matches the sleep intent of the search. The trade-offs are real. Sales rank is the lowest of the five, meaning it moves through the marketplace far more slowly than the biotin-focused options. The bottle is small at 2 oz and 60 capsules, so a full serving each night lasts a month. And the melatonin makes it a bedtime-only product, not something you can shift to a morning routine if it stops fitting your day. **Pros:** - Only pick here with a stated melatonin dose - Split-dose capsules allow starting at 1.5mg - Biotin, calcium and magnesium in one capsule - Listed under Sleep Supplements, not just biotin **Cons:** - 60 capsules is the joint-smallest bottle in the set - Bedtime use only because of the melatonin - Lowest sales rank of the five, so a slower-moving item - Fewer published specifications than the Nature's Bounty picks [Check Price on Amazon](https://www.amazon.com/dp/B0FBCF9FMW?tag=mundocisco-20) ## 2\. NUTRAHARMONY Biotin, Collagen, Hyaluronic Acid & Keratin — Best premium **A four-ingredient beauty stack in a single capsule for shoppers who want more than biotin without hunting down separate bottles.** [![NUTRAHARMONY Biotin, Collagen, Keratin and Hyaluronic Acid 60-capsule bottle — a four-active beauty complex in one pill](https://m.media-amazon.com/images/I/51LbJer4I+L._SL500_.jpg)](https://www.amazon.com/dp/B09RKDGYJD?tag=mundocisco-20) **Best for:** shoppers who want biotin, collagen, keratin and hyaluronic acid in one capsule **Skip it if:** you prefer softgels or a larger bottle to reduce reorders NUTRAHARMONY builds its 60-capsule bottle around four named actives: biotin, hydrolyzed collagen, keratin and hyaluronic acid, with a vitamin B-complex, vitamins A and E, and botanical extracts added in. The brand says the formula is made without GMOs, gluten and unnecessary fillers. That combination is what earns the premium position in this shortlist. None of the other picks names collagen and keratin together in its short bullets, and the two daytime alternatives that come close either wrap them into a much larger 21-in-1 formula or leave them out. The compromise is the bottle size and format. At 60 capsules and 2.4 oz, it is the joint-smallest in the set and the most expensive position of the five picks, so a daily serving reorders faster than any softgel here. Capsules also mean a slightly larger pill footprint than a softgel of the same active weight, which matters if swallowing pills is a friction point in your routine. There is no sleep ingredient in the listing, so this is a daytime beauty formula regardless of when you take it. **Pros:** - Names biotin, collagen, keratin and hyaluronic acid in one capsule - Adds a B-complex, vitamins A and E per the listing - Brand says non-GMO and gluten-free - Aimed at both men and women **Cons:** - Highest price position of the five picks - 60-capsule bottle is the joint-smallest here - No sleep ingredient, so does not address the keyword - Capsule format rather than softgel [Check Price on Amazon](https://www.amazon.com/dp/B09RKDGYJD?tag=mundocisco-20) ## 3\. Nature's Bounty Advanced Hair, Skin & Nails — Best budget pick **A 150-softgel bottle at a mid-range price from a brand that has been shipping hair vitamins since 2015.** [![Nature's Bounty Advanced Hair, Skin and Nails 150 rapid-release softgels — the largest daytime bottle here at a mid-range price](https://m.media-amazon.com/images/I/41j4CBYG0SL._SL500_.jpg)](https://www.amazon.com/dp/B0072F8D7S?tag=mundocisco-20) **Best for:** a long-running daily routine at a mid-range price with a familiar label **Skip it if:** you want the sleep support the keyword implies Nature's Bounty Advanced Hair, Skin & Nails comes in a 150-count rapid-release softgel bottle at 1 lb, released in 2015 and still in circulation. The listing highlights biotin plus antioxidants A, C and E and hyaluronic acid. Within this shortlist it is the third cheapest and the second-fastest seller, so the balance of price and category traction is strong. It is also the largest bottle other than the Micro Ingredients 400-count upgrade, which makes it the natural choice for anyone who dislikes reordering. The obvious catch is that it has nothing to do with sleep. Nature's Bounty positions it as a daytime beauty softgel and the ingredient list confirms it: no melatonin, no magnesium claim, no nighttime framing. If you arrived at this article after searching for the sleep angle, treat this pick as the daytime companion rather than the answer. Rapid-release softgels are gentler on swallowing than large capsules, which is a small but real advantage if you have struggled with the NUTRAHARMONY-style pill format. **Pros:** - 150 softgels is the second-largest bottle here - Rapid-release softgel format - Adds vitamins A, C, E and hyaluronic acid per the listing - One of the faster-moving picks in this set **Cons:** - No sleep ingredient anywhere in the listing - Full serving size not shown in the shortlist data - Bulkier bottle at 4.74 x 2.66 x 2.66 in - Sits under biotin, not Sleep Supplements [Check Price on Amazon](https://www.amazon.com/dp/B0072F8D7S?tag=mundocisco-20) ## 4\. Micro Ingredients Hair Skin and Nails Vitamins — Best upgrade **A 400-softgel supply the brand describes as a 21-in-1 complex, aimed at a household that hates reordering.** [![Micro Ingredients 400-softgel hair, skin and nails bottle — a 21-in-1 formula billed as a 133-day supply](https://m.media-amazon.com/images/I/41mVggX5-TL._SL500_.jpg)](https://www.amazon.com/dp/B0F4HSLBW8?tag=mundocisco-20) **Best for:** one household stocking a beauty complex for months without reordering **Skip it if:** you dislike very large bottles or want a simpler ingredient list Micro Ingredients builds this softgel around a 21-in-1 ingredient list that the brand says includes biotin, hydrolyzed collagen, hydrolyzed keratin, hyaluronic acid, argan oil, horsetail extract, PABA, vitamins A, C, D, E, a full B-complex, plus zinc and selenium, all suspended in MCT oil. The full title calls the 400-count bottle a 133-day supply. That is the story here: this is a stockpile product, and the sheer count is what earns the upgrade slot rather than the premium one. Two honest weaknesses. First, published specifications are the thinnest of any pick in this set, so there is little to verify beyond the count. Second, a 21-in-1 formula is inherently harder to reason about than a shorter list, because the dose of each ingredient shrinks the more you add, and the listing does not spell those doses out in the fields I have here. And, as with every daytime pick, there is no melatonin and no sleep claim, so this is not a nighttime supplement no matter how many actives are on the label. **Pros:** - 400 softgels is by far the largest bottle in this set - Brand claims a 21-in-1 beauty complex with MCT oil - Softgel format for easier swallowing - Brand says non-GMO, no soy, dairy or gluten **Cons:** - Fewest published specifications of any pick here - Ingredient doses not visible in the listing fields - Premium price position without a sleep angle - A very large bottle is easy to abandon halfway through [Check Price on Amazon](https://www.amazon.com/dp/B0F4HSLBW8?tag=mundocisco-20) ## 5\. Nature's Bounty Biotin Hair Skin and Nails Vitamins — Best minimal setup **The simplest option in the set, a biotin-forward softgel at the cheapest price position, for a beauty routine with nothing extra to think about.** [![Nature's Bounty Biotin Hair Skin and Nails Vitamins 120 softgels — the cheapest and simplest daytime pick in the set](https://m.media-amazon.com/images/I/41VHR1TpCqL._SL500_.jpg)](https://www.amazon.com/dp/B009SZXM4E?tag=mundocisco-20) **Best for:** a simple biotin-forward softgel with no extras to think about **Skip it if:** you want collagen, keratin or a broader B-complex in the same pill This 120-softgel bottle is the cheapest of the five and the fastest mover in the shortlist by category rank. Nature's Bounty leads with biotin as the hero ingredient, and the listing mentions the same B-vitamin family framing across hair, skin, nails, nervous system and energy metabolism, described as beauty and wellness support. The bottle is small at 2.24 oz and 4.17 x 1.98 x 1.98 in, which makes it the easiest to travel with of the softgel picks. The trade-off is deliberate simplicity. There is no collagen, no keratin and no hyaluronic acid on the label, so anyone shopping for a fuller beauty stack should step up to the NUTRAHARMONY capsule or the Micro Ingredients softgel. There is also, again, no sleep ingredient here, so this is a daytime pick that ends up in the shortlist because it is the cheapest anchor point and the one buyers choose most often here by category rank. If you want a beauty vitamin without deciding between ingredients, this is the low-friction answer. **Pros:** - Cheapest of the five picks - Small, easy-to-pack bottle at 2.24 oz - Softgel format with a single hero ingredient - The fastest-moving pick in this set **Cons:** - Biotin-only focus with no collagen or keratin - No sleep ingredient in the listing - Simpler formula than the two premium picks - Only 120 softgels, so a mid-length supply [Check Price on Amazon](https://www.amazon.com/dp/B009SZXM4E?tag=mundocisco-20) ## Biotin, collagen or a full B-complex: what actually differs? Every product in this shortlist leads with biotin. That is why four of them share the same B7 (Biotin) category path. But the ingredient list past biotin is where the real differences show up, and it is worth reading before you pay a premium. - **Biotin only, plus a broader B-focus.** The 120-softgel Nature's Bounty biotin bottle sticks close to biotin as its hero. The listing frames it around hair, skin, nails, nervous system and energy metabolism, all standard B-vitamin territory. - **Biotin plus antioxidants.** The 150-softgel Nature's Bounty Advanced Hair, Skin & Nails adds vitamins A, C and E and hyaluronic acid according to the label. The brand ties C to collagen production, which is a claim, not a measurement. - **Biotin, collagen, keratin and hyaluronic acid.** The NUTRAHARMONY capsule names all four in a single bullet. That is the shortest path to a full beauty stack in one pill within this set. - **A 21-in-1 stack.** Micro Ingredients adds argan oil, horsetail extract, PABA, zinc and selenium on top of the four above. More is not automatically better, and the per-ingredient dose is not shown in the shortlist data. - **A nighttime formula.** Angry Supplements steps outside the beauty-only frame with melatonin and magnesium for wind-down, at the cost of a leaner beauty ingredient list. The practical read: if biotin is the point, the cheapest pick already covers it. Anything more you pay is for extra actives or for the sleep angle. ## How long does one bottle really last? Bottle counts are the easiest number to compare across this set, and they tell you exactly how often you will reorder if you take one serving a day. The counts run from 60 to 400. 1. Micro Ingredients: 400 softgels. The full title calls this a 133-day supply. 2. Nature's Bounty Advanced Hair, Skin & Nails: 150 softgels. 3. Nature's Bounty Biotin Hair Skin and Nails: 120 softgels. 4. NUTRAHARMONY Biotin, Collagen, Keratin: 60 capsules. 5. Angry Supplements Hair Envy PM: 60 capsules. Two things to watch. First, softgel and capsule counts are not the same as serving counts. If a product's serving is two capsules, the bottle lasts half as long as the count suggests, and the shortlist data does not always list the serving size. Read the label before you plan a month's supply. Second, larger is not always better with supplements, because opening a bottle starts the clock on freshness. A 400-count bottle you finish is a bargain; a 400-count bottle you abandon at halfway is not. If reorder friction is your enemy, Micro Ingredients wins outright. If you want to test a formula before committing, the two 60-count bottles are the low-risk entry points. ## What the listings do not tell you Even a careful read of the Amazon page leaves gaps a buyer of hair vitamins should know about. - **Time to see a result.** Hair grows slowly. Any change is usually months, not weeks. No listing here commits to a timeline, and you should not expect one to. - **Serving-size arithmetic.** Some of these bottles use one capsule per serving; others use two. The count on the front of the label is not always the number of days it lasts. - **Interactions.** Biotin can interfere with certain lab tests, and melatonin interacts with several medications. Neither warning is in these bullets in a form I can quote. - **Formulation changes.** Model numbers and release years hint that Nature's Bounty has iterated on these bottles since 2015 and 2016\. Formulas can change without an obvious label update, so the current bottle is the source of truth, not older photos. - **Who is behind the brand.** The two Nature's Bounty products lean on 50 years of company history in their bullets. NUTRAHARMONY, Angry Supplements and Micro Ingredients are less familiar names, so the brand claim carries more weight in reading the label carefully. None of this is a reason to avoid the category. It is a reason to read the current label rather than rely on the shortlist alone before you take the first capsule. ## The verdict If you searched for the best hair vitamins for sleep and meant it literally, Angry Supplements Hair Envy PM is the answer, because it is the only product in this set whose listing pairs biotin with a melatonin sleep claim. Take it at night, start with one capsule for 1.5mg of melatonin, and step up to the full 3mg serving once you know how you respond. If the sleep framing is loose and you actually want a strong daytime hair, skin and nails formula, the pick flips to NUTRAHARMONY. Four named actives, biotin, collagen, keratin and hyaluronic acid, in one 60-capsule bottle earn the premium spot. The cutoff is simple: do you want a nighttime product, or a beauty complex you take with breakfast? Nothing here does both well, and pretending otherwise would be the trap. If price is the deciding factor and you only want biotin, the 120-softgel Nature's Bounty biotin bottle is the cheapest anchor. If you never want to reorder, the 400-softgel Micro Ingredients bottle is the upgrade. Match the pick to the routine and the shortlist reads cleanly. ## FAQ ### Do any of the best hair vitamins for sleep actually contain melatonin? Any of the best hair vitamins for sleep in this shortlist that actually contain melatonin narrows to one product: Angry Supplements Hair Envy PM. The listing states 3mg of melatonin per serving with 1.5mg per capsule, alongside biotin, calcium and magnesium in a 60-capsule bottle. The other four picks are daytime hair, skin and nails formulas with no melatonin on the label. ### Is a nighttime hair vitamin worth it over a regular one? A nighttime hair vitamin is worth it if you want both the biotin routine and a mild wind-down in the same capsule, so you take one bottle instead of two. If you already sleep well without a supplement, a daytime formula like NUTRAHARMONY's biotin, collagen, keratin and hyaluronic acid capsule gives a broader beauty ingredient list at the cost of the sleep angle. ### How much biotin do these bottles say they contain? How much biotin these bottles say they contain varies by product, and the shortlist data does not print every dose. Nature's Bounty's biotin softgel refers to a 10,000mcg-style formulation in its bullets. NUTRAHARMONY and Micro Ingredients name biotin without stating the amount in the fields I have. Always read the current Supplement Facts panel before dosing. ### NUTRAHARMONY vs Micro Ingredients for a broader beauty stack? NUTRAHARMONY vs Micro Ingredients splits on scale and simplicity. NUTRAHARMONY names four core actives in a 60-capsule bottle: biotin, collagen, keratin and hyaluronic acid. Micro Ingredients extends that into a 21-in-1 softgel in a 400-count bottle the brand calls a 133-day supply. Choose NUTRAHARMONY for a shorter list; choose Micro Ingredients for a household stockpile. ### What is the most common mistake buying hair vitamins? The most common mistake buying hair vitamins is expecting a fast, visible change. Hair grows slowly, so any effect from biotin, collagen or a broader beauty complex is measured in months. A second mistake is buying a giant bottle before you know the formula agrees with you. Start with a 60- or 120-count bottle from this shortlist before committing to a 400-softgel supply. The clean next step is to decide the routine before the product. If your goal is a nighttime capsule that folds hair support into a wind-down, buy the Angry Supplements PM bottle, start at 1.5mg of melatonin and give it two weeks before deciding. If your goal is a daytime beauty stack, NUTRAHARMONY's four-active capsule is the strongest pick here, and the two Nature's Bounty softgel bottles are the low-risk anchors below it. The keyword promises a sleep angle, but the honest read of this shortlist is that only one product delivers it, and the other four are worth buying for a different reason entirely. *Last updated: September 22, 2026\.
