9 Best Biotin Shampoos: Your Secret Weapon for Thinning Hair

If you’ve experienced hair thinning or hair loss, there’s a good chance you’ve heard about biotin, or vitamin B7. But what exactly is biotin, and can it really help with hair regrowth? “Biotin is a B vitamin important for metabolic processes, and it supports the protein keratin [which is] the basic protein in hair,” explains Alice McCarney, owner of AD Hair Studio in New York City. Often, hair thinning is a sign of a biotin deficiency, as are brittle nails, or possibly even skin rashes. For more severe deficiencies, your physician may recommend a biotin supplement. But for hair growth, hair care products with biotin may provide a boost in volume—plus, they can protect against issues like breakage, dryness, and split ends.

“Because biotin strengthens hair, it’s great to use a shampoo and conditioner that contains biotin to improve strength, vitality, and thickness, as well as help your hair grow,” recommends McCarney. Stronger, fuller hair in a bottle? Yes, please. Read on for the best biotin shampoos for every hair type and need.

The Best Biotin Shampoos for Healthy Hair

1. Best-smelling: OUAI Fine Hair Shampoo

Packed with keratin, chia seed oil, and biotin, this paraben-free shampoo is a miracle-worker for frizzy and thin hair. Not only do the healthy ingredients nourish and strengthen your hair, this shampoo’s citrusy, floral, can’t-quite-put-your-finger-on-it fragrance will have you hooked.

2. Best for damaged hair: ORIBE Gold Lust Repair and Restore Shampoo

A favorite of McCarney’s, this formula features a “bio restorative complex” containing biotin, niacinamide, collagen, and caffeine to help rejuvenate and strengthen hair starting at the hair follicle. That, plus amino acids to help rebuild hair, and moisturizing argan oil boosts shine.

3. Best for chemically-treated hair: BRIOGEO Blossom & Bloom™ ginseng + biotin volumizing shampoo 

Made with ginseng, ginger, vitamin B5, and biotin, this scalp-refreshing formula is safe to use on keratin-treated, chemically relaxed, and color-treated hair. Even better, it’s vegan, gluten-free, cruelty-free, and made with 93% natural ingredients.

4. Best shampoo and conditioner duo: HAIRTAMIN Biotin Shampoo & Conditioner Set

Known for its hair-growth vitamins, the brand also has a great shampoo and conditioner for healthier hair featuring—what else?—biotin! It’s also got aloe vera, turmeric, and peppermint and lavender essential oils that boast numerous benefits—from soothing to healing. Used regularly and in tandem, they’ll give hair a major boost in volume and elasticity.

5. Best for curly hair: R+CO Dallas Biotin Thickening Shampoo

Cleverly called “Dallas” because of that bombshell volume you’ll have when you use it, this shampoo uses biotin and vitamin B5 and saw palmetto berry extract to give hair a thicker appearance, as well as nourishing coconut oil. Plus, it lathers like a dream without moisture-stripping sulfates, parabens, or mineral oil.

6. Best for mature hair: ALTERNA Caviar Anti-Aging Clinical Densifying Shampoo

Biotin takes a supporting role in this formula (which, for the record, can be used by anyone of any age). The real star here is the caviar extract, which is a rich source of fatty acids and restores shine, bounce, and fullness to dry hair.

7. Best personalized: PROSE Custom Shampoo

Here’s how it works: You fill out a fun quiz to figure out the perfect formula for your hair—and while biotin may not be included in every bottle, if you found yourself on this article, it very likely will be. Even better, the other ingredients will also be tailored to your needs—from tea tree oil (for dandruff) to apple cider vinegar (for removing product buildup) to green tea (for antioxidant protection). Plus, the formulas are always paraben-, phthalate-, and sulfate-free.

8. Best for hair health: KLORANE Shampoo with Quinine and B Vitamins

Love heat styling? This formula is like a protein shake for damaged hair. With a cocktail of B vitamins including biotin and panthenol, it helps fortify each strand while also balancing the scalp.

9. Best for men: KÉRASTASE Bain Densité Homme

Of course, hair loss doesn’t discriminate between men and women, so guys, we’ve got you covered (so to speak). Made with biotin and texturizing polymers, this formula helps treat and prevent baldness, with the added benefit of looking fancy in the shower.
