3 Shampoo Ingredients Experts Swear By To Regrow Thinning Hair

Biotin, often known as vitamin B7 or vitamin H, is a water-soluble supplement often associated with stronger, healthier hair. “It promotes healthy hair growth by improving the scalp and strands,” Dr. Methil stated.

Biotin strengthens and thickens hair, adding volume and body. Biotin also promotes new growth, thickening hair over time. Make sure biotin is a top-listed shampoo component.

Saw palmetto extract in shampoo has many hair benefits, Dr. Methil said. “This active ingredient can deliver a significant boost of natural nutrients to the scalp.

It can nourish and strengthen hair follicles for thicker, healthier strands. Saw palmetto extract also preserves scalp oils, avoiding dryness and irritation. This fights dandruff and other scalp issues.”




Keratin Dr. Methil stated keratin protein strengthens and protects hair, making it thicker and fuller. The expert says "Shampoos containing keratin can help thinning hair by providing an additional source of this powerful protein."

Regular use of these shampoos thickens and conditions hair, adding body and gloss. Keratin-based shampoos strengthen hair follicles, reducing breakage and thinning."
