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 definitely get biotin orally via a supplement or through your diet (it’s found in foods such as salmon and egg yolks), it's is also a staple in many topical hair products. It’s a mainstay in many shampoos, an easy way to help ensure stronger, thicker, and fuller hair with every wash. And really, who doesn’t want that?

Saw palmetto extract is also prevalent in the formula, as is rosemary, aloe, and coconut, and, of course, biotin, to help both stimulate the scalp and help hair grow longer and fuller. An added benefit? It also leaves hair feeling extra smooth and soft, which is always a good thing.

No matter whether you’re dealing with a dry, flaky scalp, an oily scalp, or even dandruff, this sudser can help. It’s sulfate-free and contains a variety of natural oils to combat dryness, deep cleanses the scalp with tea tree oil and rosemary, and even has zinc pyrithione, one of the best anti-dandruff ingredients out there. And while all of those work on the scalp, there’s also biotin in the mix to thicken the hair, too.

Hairgenics Pronexa Hair Growth Shampoo with Biotin
What We Like
  • Minimizes shedding

  • Effective formula

  • Hair feels clean

What We Don't Like
  • Expensive

Technically speaking, minoxidil is the only FDA-approved ingredient that re-grows new hair. That being said, the anecdotal proof from rave reviews of this product make it well worth a try for those dealing with excess shedding. There’s thickening biotin as well as DHT-blockers like saw palmetto extract, which goes a long way to stimulating growth and helping to prevent hair loss. (DHT is a hormone known to be a major contributing factor toward hair loss.) FYI, you’ll need to use it regularly for at least two months to see results, so just be patient.

Hask Biotin Boost Thickening Shampoo
What We Like
  • Inexpensive

  • Adds volume and thickness

  • Not overly drying

What We Don't Like
  • Strong scent

As a general rule of thumb, biotin is a great ingredient for all hair types, but those with fine or limp strands can benefit even more from the B vitamin. It’s ideal for bulking up hairs and is even more effective when paired with plumping collagen and caffeine-rich coffee (which is great for stimulating the scalp and boosting hair at the root), as it is in this shampoo. The trio leaves hair extra full and extra voluminous, with tons of lift.

Hair Type: Fine/thin | Sulfate-Free: Yes | Scent: Original | Size: 12 fl. oz | Byrdie Clean: No | Cruelty-Free: Yes

The biotin in this sudser helps boost the keratin structure of your hair, increasing strength and resilience. But it’s not the only standout ingredients; this also boosts conditioning B5, shine-enhancing coconut oil, and saw palmetto extract, a naturally volumizing ingredient to make your mane look noticeably fuller with every wash. It’s worth the price, for sure, especially for those with limp locks.

What We Like
  • Moisturizes curls

  • No sulfates or silicones

Not all shampoos are created equal, and this fact holds especially true when talking about curly hair. This pick contains no sulfates or silicones (both things to be wary of if you have curls) but does offer plenty of hydrating ingredients and oils to add back the moisture that curly hair needs. On top of that, biotin and protein-rich quinoa help maintain the structure and integrity of your spirals.
