Best Hair Growth Supplements for Women 2025

TS By the Top Shelf Picks team

If you've noticed more hair in your brush than usual — or a ponytail that feels noticeably thinner than it did a year ago — you're not imagining it, and you're far from alone. Thinning hair affects women of all ages, triggered by everything from postpartum hormonal shifts to chronic stress to plain old genetics. The good news: the best hair growth supplements for women have come a long way, and a few genuinely earn their shelf space.

We narrowed it down to two standout options that approach the problem from different angles. One leans on decades of clinical research and a track record trusted by millions. The other bets on cutting-edge liposomal delivery and a multi-benefit formula that also targets skin. Neither is a magic pill — consistent use over weeks and months is non-negotiable — but both have real science and real users behind them.

Here's what you need to know before you buy.

Viviscal

Viviscal Hair Growth Supplements for Women, Thicker Fuller Hair Support for Thinning Hair and Hair Loss, with Biotin and Marine Collagen, Drug-Free, 180 Tablets, 90-Day Supply Blister Pack 180 Count (Pack of 1)

★★★★★★★★★★4.330,095 ratings

Editor's Pick

Viviscal has been in the hair-growth conversation longer than almost any competitor, and that staying power is backed by substance. The formula combines its signature marine collagen complex with Biotin, Zinc, and Vitamin C — nutrients that feed hair follicles from the inside out rather than just coating the strand. With 25+ years of research behind it and over 30,000 ratings averaging 4.3 stars, this is the supplement you reach for when you want a proven track record, not a trend. Viviscal explicitly supports women dealing with stress-related shedding, hormonal shifts, postpartum loss, and age-related thinning, and the 90-day supply blister pack (180 tablets) is built around the realistic timeline it takes to see meaningful results — typically around three months. It's drug-free and safe for color-treated and fine hair. If you're impatient or expecting results in a few weeks, temper expectations; this is a long game. But if you commit, the sheer volume of long-term user evidence is hard to argue with.

Why we picked it

I keep coming back to Viviscal as my top recommendation because it solves the hardest problem in this category: trust. Supplements are easy to formulate and even easier to market, but a 25+ year research history combined with over 30,000 consumer reviews is genuinely rare. When a product survives that long with that kind of engagement, it's not hype — it's results. The specific combination of marine collagen, Biotin, Zinc, and Vitamin C targets the nutritional gaps most commonly tied to female hair thinning, and the drug-free formulation means it's accessible to a broad range of women regardless of health background.

I'm confident recommending Viviscal to most women experiencing thinning, shedding, or postpartum loss who want the most clinically validated option available without a prescription. The 90-day supply format is also a smart nudge — it commits you to the timeline the research actually supports, rather than letting you give up after three weeks. MaryRuth's is a genuinely compelling alternative with exciting delivery technology and faster early results in clinical testing, but for most buyers, Viviscal's depth of evidence is the safer, smarter starting point.

MARYRUTH'S

MaryRuth's Hair Growth Max Liposomal for Women | Lustriva® + Biotin 10000mcg + Pumpkin Seed Oil | Thicker Hair | Hair Care | Wrinkles, Fine Lines, Skin Care | Ages 18+ | CLP Certified | 15.22 Fl Oz

Editor's Pick

MaryRuth's Hair Growth Max Liposomal stands out from the typical capsule-and-tablet crowd with a liquid liposomal format and an almond cookie flavor that you can drink straight or drizzle over food — a genuine quality-of-life upgrade if you already take a handful of pills daily. The star ingredient is 160mg of Lustriva, clinically shown to support thicker, fuller hair in as early as three weeks, which is a faster claimed timeline than most competitors. A uniquely soluble form of Biotin at 10,000mcg, plus pumpkin seed oil, saw palmetto, and amla fruit, rounds out a formula that also targets facial wrinkles and skin smoothness — so it's pulling double duty for women who want hair and skin benefits in one bottle. The liposomal delivery system is a meaningful differentiator for absorption, not just a marketing buzzword. That said, MaryRuth's has roughly a tenth of the review volume Viviscal has, so the long-term real-world track record is still building. It's an excellent pick for vegan shoppers or anyone who prioritizes clean-label credentials — it's Vegan, Gluten-Free, Dairy-Free, Clean Label Project Certified, and B Corp Certified.

The bottom line

For most women navigating thinning hair, hair loss, or postpartum shedding, Viviscal is the place to start. Its combination of marine collagen, Biotin, Zinc, and Vitamin C is backed by more than two decades of research and a user base that numbers in the millions — that's a level of real-world validation no newcomer can replicate overnight. Commit to the full 90-day supply and give the formula the time it needs to work from the inside out.

If you prefer a liquid format, follow a vegan lifestyle, or want a supplement that tackles skin concerns alongside hair growth, MaryRuth's Hair Growth Max Liposomal is a strong honorable mention worth serious consideration. Its liposomal delivery and Lustriva ingredient bring something genuinely different to the table. But when in doubt, go with Viviscal — it's earned its reputation.

Frequently asked questions

How long does it take to see results from hair growth supplements for women?

Most research-backed supplements, including Viviscal, cite results in as little as 3 months with consistent daily use. Hair growth is a slow biological process — don't judge any supplement before the 90-day mark. MaryRuth's Lustriva ingredient has shown results in clinical testing as early as 3 weeks, but meaningful thickness and fullness still typically take longer to become noticeable in the mirror.

Are these hair growth supplements safe to take if my hair is color-treated or chemically processed?

Yes — Viviscal explicitly states it's safe for color-treated and fine hair. Since both supplements work internally by nourishing hair follicles rather than applying anything topically, they don't interfere with chemical treatments. That said, always check with your doctor if you have specific health conditions or are taking other medications.

What's the difference between a liposomal liquid supplement and a standard tablet for hair growth?

Liposomal delivery, like the format MaryRuth's uses, encapsulates nutrients in tiny lipid structures designed to improve absorption through the gut lining. The idea is that more of the active ingredient actually reaches your system. Standard tablets like Viviscal rely on your digestive process to break down and absorb the nutrients. Both approaches have clinical support; the liposomal format is newer and theoretically more efficient, but Viviscal's tablet formula has a much longer real-world track record.
