In the world of haircare, biotin is arguably one of the most buzzed-about ingredients. Also known as vitamin B7, it gets a ton of play in the supplement world and is well-known for its ability to help promote stronger and healthier hair. (Seriously, good luck finding a hair supplement that doesn’t contain it.)

While you can get biotin orally via a supplement or through your diet (think salmon and egg yolks), it's also a staple in many topical hair products. Many shampoos contain biotin, which makes it easy to ensure you get stronger, thicker, and fuller hair with every wash. And really, who doesn’t want that?

Who else recommends it? Good Housekeeping, Cosmopolitan, and Healthline all picked Briogeo Biotin Volumizing Shampoo.

What do buyers say? 79% of 300+ Amazon reviewers rated this product 4 stars or above.

There’s a lot to like about this shampoo. First and foremost, the sulfate-free formula works on all textures, from fine and straight to thick and curly (and also won’t strip color). It’s 98 percent natural, relying on ginger and ginseng to deep clean the scalp—a good thing when it comes to promoting healthy hair growth. Meanwhile, biotin and vitamin B5 (panthenol) strengthen and thicken hair. It’s a top choice for Rubyna Kim: “This is probably my favorite biotin shampoo. It contains a natural thickener called maltodextrin that helps individual strands look thicker and fuller,” she says.

Final Verdict

The Briogeo Blossom & Bloom Ginseng + Biotin Hair Volumizing Shampoo is our overall favorite as a sulfate-free option that works on all hair types and textures. You can find great biotin shampoos at the drugstore, too; the OGX Thick & Full Biotin & Collagen Shampoo and Love Beauty Planet Vegan Biotin Shampoo are two of our favorites. And if you’re dealing with hair loss, consider trying the Pronexa Hair Growth Shampoo with Biotin, a fan fave that contains ingredients that may help ward off shedding while also strengthening the hair.

What to Look for in a Biotin Shampoo

Vitamin B7 or Vitamin H

If you don’t see biotin listed as such, Kim suggests looking for these ingredients—vitamin B7 or vitamin H—which are alternate names for biotin. You can also just search for any hair cleanser that says it boosts thickness and reduces breakage, and then look to the ingredients listings for biotin.

Strengthening Ingredients

Think fortifying proteins such as soy, silk, and keratin so that you get even more benefit from the formula. Saw palmetto also has been shown to help boost the strength of hair follicles.

FAQ
  • What are the benefits of biotin shampoos?

    “Biotin shampoos aren’t a miracle product for hair growth, but they can strengthen follicles, boost the keratin structure of the hair, combat dryness, and help increase the hair’s density,” says Kim.

  • How often should you use biotin shampoos?

    Kim suggests using these every time you wash for maximum benefits. However, it's also a good idea to look at the instructions on the label for shampoo for the frequency of use just to be sure.

  • How long do biotin shampoos take to work?

    Unfortunately, there’s no set answer here; Kim says it all depends on your hair type, how damaged your hair is, and the product you choose. Check the label and some of the product reviews to get an idea of what to expect.
