Healthy hair not only looks good, but it feels good. Unfortunately, as we age, our hair can lose its density and luster, leaving us with lackluster strands that don’t perform the way we want it to. The best way to battle this is with biotin, also known as vitamin B7. This B-complex vitamin, found in foods like salmon and egg yolk, does everything from strengthening to plumping to encouraging hair growth. Although you can load up on biotin through your diet, there are specially-formulated shampoos that can boost your hair’s health, one shower at a time.
Below, discover the best biotin shampoos for thicker, glossier hair.
Best Overall: Briogeo Blossom & Bloom Ginseng + Biotin Volumizing Shampoo
This shampoo is equal parts cleansing and stimulating. Ginger and ginseng awaken your scalp and follicles, which helps to banish dandruff and to improve hair's manageability. Biotin reinforces hair by delivering essential nutrients that coat each strand. Plus, this formula is sulfate-free, making it ideal for every hair type and routine.
Best Budget: Renpure Biotin & Collagen Thicken + Strengthen Shampoo
The best thing about this plant-based shampoo is that it's free of "baddies"—sulfates, phthalates, parabens, and dyes. It's also a steal. With its combo of biotin and collagen, it improves hair's density by thickening the strands for a fuller look and feel. Another lovely treat is the scent; enjoy notes of jasmine, bergamot, and apple.
Best Drugstore: OGX Thick & Full Biotin & Collagen Shampoo
No texture? No problem. With this shampoo, the plump is real. Fuller, healthier hair is one wash away thanks to ingredients like wheat protein, biotin, and collagen. The creamy consistency wraps around each strand, thickening your hair with every application. It's also gentle enough to use on sensitive scalps.

Among its many benefits—adding volume, softness, and shine—users also found that their hair overall felt healthier and fuller. One even notes that she could finally run her fingers down her strands without breakage.
Best Luxury: Kevin Murphy Plumping Wash
While we love this product for its vanity-approved millennial pink bottle, the formula within definitely deserves some praise, too. Blended with oleanolic acid, derived from the lovely hemsleya root, and acai berry extract, this shampoo is a pro at reversing the signs of follicle aging. Silk amino acids offer hydration to thirsty hair, making strands bouncier and much more flexible. Apply the luxurious formula into wet hair, from root to tip, lather for a minute or two, then rinse.
