19 Over-the-Counter Hair Growth Products That Actually Work

Oprah Daily Logo By Brigitt Earley of Oprah Daily | Slide 1 of 20: There are plenty of ways to help hair grow faster and longer—diet, vitamins, and even the shampoo you use can all affect hair thickness and health. But sometimes loss is due to uncontrollable factors, like genetics, medical treatment, conditions like trichotillomania, or fluctuations in hormones thanks to childbirth, menopause, or even stress. That doesn't mean you have to live with thinning strands and patchy bald spots, though. While you should certainly speak to your doctor about severe hair loss, there are over-the-counter hair growth products that can help those with mild to moderate cases. These contain growth-stimulating ingredients like topical Minoxidil (the only truly proven ingredient for hair loss), as well as biotin, collagen, keratin, vitamin A, and more. The best part: They're suitable for all types of hair—straight, 4C curly, natural...you name it. But how do you know which hair growth products are potent enough to actually work? We asked hair and skincare experts, including dermatologists and trichologists, to share their picks for the fast-acting hair growth shampoos, leave-in treatments, vitamins, and supplements for both women and men.
