The Kérastase Spécifique Bain Divalent is a favorite of New York City-based board-certified dermatologist Kavita Mariwalla, MD, specifically for “strengthening hair, especially as we age,” she says. It’s also formulated for people who are dealing with greasy scalps but have brittle, dry hair. The shampoo targets these concerns with vitamin B6, which works to slow sebum production, along with glycine, an amino acid that deeply moisturizes strands.
Davines’ Volu Shampoo amps up hair volume, thanks to turnip root extract, which contains minerals like phosphorus, iron, and calcium that fortify hair. The shampoo also includes a trio of vitamins (A, B, and C) that boost scalp health. Just one wash with this shampoo leaves hair feeling soft and nourished — and smelling super fresh and clean.
In addition to smelling like absolute heaven (or a blend of rose, Italian lemon, jasmine, and white musk, to be exact), Ouai’s Fine Hair Shampoo comes highly recommended by Dr. Mariwalla. “Whether your hair is thinning or you feel like it just looks flat, this makes a difference with chia seed oil that penetrates the hair to give it hydration and bounce, along with biotin and keratin,” she says.
Stacy Chimento, MD, a board-certified dermatologist at Riverchase Dermatology in Bay Harbor Islands, Florida, recommends Alterna’s Caviar Clinical Densifying Shampoo because of its effective, jam-packed formula. It contains strengthening biotin and keratin; amino acids like hydrolyzed vegetable and hydrolyzed soy proteins to help thinning hair build new strands; and moisturizers glycerin and sunflower seed oil to keep hair shiny and silky.
As a bonus, you won’t find any synthetic colors and dyes in this formula. “It also removes environmental residues and excess sebum, which allows for thicker-looking hair to rise to the surface,” Dr. Chimento says.
Dr. Mariwalla also recommends Isdin’s Lambadapil Hair Loss Shampoo because of its nourishing formula, made of ingredients like zinc and biotin, which “really make the hair look and feel thicker and fuller.” You’ll also find ginseng, which promotes hair growth, along with hydrolyzed wheat protein for strengthening hair inside and out.
Bring on the biotin. In R+Co’s Dallas Biotin Thickening Shampoo, the strengthening ingredient coats each strand of hair so that it looks much more full. This formula hydrates and nourishes hair, thanks to antioxidant-rich moringa seed extract, as well as advanced polymers that help add even more body and bounce to your style.
