Hair thinning and hair loss affect both men and women and can take a real toll on confidence. While genetics, hormones, stress, and lifestyle all play a role, scalp health is the foundation of healthy hair growth—and that starts with the right shampoo.
Dermatologists often recommend shampoos formulated with clinically studied ingredients like biotin, niacinamide, caffeine, rosemary oil, and scalp-soothing actives. These shampoos don’t magically regrow hair overnight, but they create the ideal environment for stronger, fuller-looking hair by reducing breakage, supporting follicles, and improving scalp circulation.
Below are 5 dermatologist-recommended hair growth shampoos that are gentle enough for regular use and effective enough to make a visible difference over time.
