Best Hair Vitamins: Top 10 Supplements for Stronger, Longer Locks
Are you looking for the best hair vitamins for women to help you achieve longer, stronger, and healthier hair? You’re not alone. Many women struggle with thinning hair, breakage, and slow growth. Fortunately, the right hair growth vitamins and supplements can make a big difference. In this article, we’ll cover the top 10 best hair vitamins and what to look for when choosing a supplement for your hair.
Why Take Hair Growth Supplements?
Before we dive into the best hair vitamins for women, let’s talk about why you might want to consider taking a hair growth supplement in the first place:
- Nutrient deficiencies: Certain nutrient deficiencies, like low iron or biotin levels, can lead to hair loss and thinning[1]. Hair supplements can help fill in those nutritional gaps.
- Aging: As we get older, our hair naturally becomes thinner and grows more slowly[2]. Hair vitamins can provide the nutrients your hair needs to stay strong and healthy as you age.
- Stress: Stress can wreak havoc on your hair, causing it to thin and fall out more than usual[3]. The right supplements may help strengthen your hair and improve its resilience against stress.
- Damage: Heat styling, chemical treatments, and environmental factors can all damage your hair over time[4]. Hair vitamins can provide the building blocks your hair needs to repair itself.
Now that you know why hair growth supplements can be beneficial, let’s look at the best hair vitamins for women to help you achieve your hair goals.

The 10 Best Hair Growth Vitamins for Women
1. Viviscal Hair Growth Supplements
Key ingredients: AminoMar marine complex, biotin, vitamin C, iron, zinc | Servings: 60 tablets | Dosage: 2 tablets per day
Viviscal is one of the most popular and well-researched hair growth supplements on the market. Its star ingredient is AminoMar, a proprietary marine protein complex derived from fish and oysters. In clinical studies, Viviscal has been shown to promote hair growth, reduce shedding, and increase hair thickness[3][4].
Viviscal also contains a range of other hair-friendly nutrients, including biotin, vitamin C, iron, and zinc. Biotin helps stimulate keratin production, while vitamin C is involved in collagen synthesis[1]. Iron and zinc play important roles in the hair growth cycle[5].
2. Nutrafol Women Hair Growth Supplement
Key ingredients: Synergen Complex (biotin, keratin, saw palmetto, ashwagandha, curcumin), marine collagen | Servings: 120 capsules | Dosage: 4 capsules per day
Nutrafol is a popular hair growth supplement that takes a multi-targeted approach to hair health. Its key ingredient is the Synergen Complex, a blend of clinically effective botanicals and nutrients that address multiple root causes of thinning hair, including hormones, stress, and aging[6].
The Synergen Complex includes saw palmetto to help balance hair-thinning hormones, ashwagandha to reduce stress, and curcumin to fight inflammation. Nutrafol also contains marine collagen to provide the building blocks for hair, and biotin to boost keratin production[1][6].
In a clinical study, 80% of women taking Nutrafol reported improved hair growth and thickness after 6 months[6]. The downside is that you need to take 4 capsules per day, which may be inconvenient for some.
3. Ouai Hair Supplement for Thinning Hair
Key ingredients: Biotin, silica, ashwagandha, amino acids | Servings: 30 capsules | Dosage: 1 capsule per day
The Ouai Hair Supplement is a popular choice for thinning hair, thanks to its blend of biotin, silica, ashwagandha, and amino acids. Biotin and amino acids provide the building blocks for strong, healthy hair, while silica may help strengthen hair and reduce breakage[1]. Ashwagandha is an adaptogenic herb that helps the body cope with stress, a common cause of hair thinning[3].
One big advantage of the Ouai supplement is that you only need to take one capsule per day, making it easy to add to your routine. It’s also vegan and gluten-free.
4. Klorane Keratin Strength Hair Growth Capsules
Key ingredients: Biotin, keratin, zinc, selenium | Servings: 30 capsules | Dosage: 1 capsule per day
Klorane’s Keratin Strength Hair Growth Capsules are designed to strengthen and fortify hair from within. The star ingredients are biotin and keratin, which work together to boost the production of keratin, the protein that makes up your hair[1].
The supplement also contains zinc and selenium, two minerals that play important roles in hair health. Zinc helps regulate the hair growth cycle and may help prevent hair loss[5], while selenium is a powerful antioxidant that protects your hair from damage.
Like the Ouai supplement, Klorane’s hair growth capsules are easy to take with just one per day. They’re also free from common allergens like gluten and soy.
5. Moon Juice SuperHair Daily Hair Nutrition

The key ingredients include biotin for keratin production, saw palmetto to balance hair-thinning hormones, and pumpkin seed to provide essential fatty acids[1][6].
SuperHair also contains horsetail, an herb rich in silica, which may help strengthen hair and improve thickness. Kelp provides iodine to support healthy thyroid function, which is important for hair growth.
The downside of SuperHair is that it requires taking 4 capsules per day. However, many reviewers report noticeable improvements in hair growth, thickness, and shine after a few months of consistent use[2].
6. Hum Nutrition Hair Sweet Hair Growth Vegan Gummies
Key ingredients: Biotin, folic acid, zinc, fo-ti root | Servings: 60 gummies | Dosage: 2 gummies per day
If you struggle to remember to take pills, gummy vitamins can be a tasty and convenient alternative. Hum Nutrition’s Hair Sweet Hair gummies are a popular choice for hair growth, with a blend of biotin, folic acid, zinc, and fo-ti root.
Folic acid, or vitamin B9, is important for healthy cell growth and may help improve the health of hair follicles. Fo-ti, also known as he shou wu, is a traditional Chinese herb believed to help with hair growth, although more research is needed.
One potential downside of gummy vitamins is that they often contain added sugars and other fillers. However, Hum Nutrition’s gummies are vegan, non-GMO, and free from artificial colors and flavors.
7. SugarBearHair Vitamins
Key ingredients: Biotin, vitamin A, vitamin C, vitamin D, vitamin E, folic acid | Servings: 60 gummies | Dosage: 2 gummies per day
SugarBearHair gummies are another popular hair growth supplement in gummy form. They contain a range of hair-friendly vitamins, including biotin, vitamin A, vitamin C, vitamin D, vitamin E, and folic acid.
Vitamin A helps the skin glands produce sebum, which keeps the scalp moisturized and healthy. Vitamin C is an antioxidant that protects hair from oxidative stress and helps with collagen production[1]. Vitamin D may help create new hair follicles and improve thickness, while vitamin E helps reduce oxidative stress and improve scalp health.
SugarBearHair gummies have thousands of positive reviews from customers who report faster hair growth, reduced shedding, and improved thickness after a few months of use[2]. Keep in mind that they do contain 3 grams of sugar per serving, so they may not be ideal if you’re watching your sugar intake.
8. Vegamour GRO Biotin Gummies for Hair
Key ingredients: Biotin, folic acid, zinc, vitamins B-5, 6, and 12 | Servings: 30 gummies | Dosage: 1 gummy per day
Vegamour’s GRO Biotin Gummies are a vegan, cruelty-free option for hair growth. They contain biotin, folic acid, and zinc, along with B vitamins like vitamin B-5 (pantothenic acid), vitamin B-6, and vitamin B-12.
B vitamins are essential for healthy hair growth and may help prevent hair loss. Vitamin B-5 in particular is important for the production of keratin. The GRO gummies also contain a blend of vitamins C and E for antioxidant support.
One potential downside is that the gummies contain coconut oil and tree nuts, so they may not be suitable if you have allergies. However, they’re a good option if you’re looking for a biotin supplement that’s vegan and cruelty-free.
9. Nutrafol Men Hair Growth Supplement
Key ingredients: Synergen Complex (saw palmetto, ashwagandha, tocotrienol complex, curcumin), marine collagen, biotin | Servings: 120 capsules | Dosage: 4 capsules per day
While many hair growth supplements are marketed toward women, men can also benefit from taking a hair vitamin. Nutrafol Men is specifically formulated to address the unique causes of hair thinning in men, such as hormones and stress.
Like the women’s formula, Nutrafol Men contains the Synergen Complex, a blend of saw palmetto, ashwagandha, tocotrienols (a form of vitamin E), and curcumin. Saw palmetto in particular is important for men, as it helps block the conversion of testosterone to DHT, a hormone that contributes to male pattern baldness.
Nutrafol Men also contains marine collagen and biotin to provide the building blocks for healthy hair growth. In a clinical study, men taking Nutrafol saw a 38% improvement in hair quality and thickness after 6 months.

Reserveage’s Keratin Hair Booster is designed to support healthy hair growth and thickness with a blend of biotin, keratin, resveratrol, hyaluronic acid, and antioxidants. Keratin is the protein that makes up your hair, so supplementing with it may help strengthen strands and reduce breakage.
Resveratrol is a powerful antioxidant found in grapes and red wine that helps protect hair from damage and may even help with growth. Hyaluronic acid is a moisturizing ingredient that can help hydrate the scalp and hair follicles.
The Keratin Hair Booster also contains vitamins C and E for added antioxidant support. Reviewers report thicker, fuller hair after a few months of use, although some find the capsules difficult to swallow[2].
