15 Shampoos For Hair Growth That Actually Work

Hair loss is more common than you think and can happen to anyone. According to Dr. Eric Schweiger of Schweiger Dermatology Group in NYC, causes range from “'androgenetic' or hormone-related hair loss, stress related-hair loss, also called 'telogen effluvium,' and dandruff. Medications, vitamin deficiencies, thyroid disorders, excess styling, and autoimmune disorders can also cause hair loss and thinning.” But the good news is, there are viable solutions, starting with topical growth treatments.

When it comes to a hair growth shampoo, you have two options: prescriptions or over-the-counter treatments. Prescription shampoos like ketoconazole are "anti-androgenetic," which means they prevent two hormones associated with hair loss—testosterone and dihydrotestosterone (DHT)—by "targeting hair growth at the site of the follicle and helping to interrupt the hormone cycle locally that causes thinning,” explains Schweiger. “Over-the-counter growth shampoos typically contain amino acids and antioxidants to provide the components to rebuild hair as well as reduce damage and inflammation.”

If you think over-the-counter hair loss shampoos are for you or just want to promote growth and strength, Schwieger recommends formulas with antioxidants such as vitamin E and ginseng, amino acids, and B-vitamins to help rebuild hair and reduce environmental damage. She cautions against using shampoo with parabens, sulfates, and fragrances, which can irritate hair and reduce moisture.

And remember hair growth is a slow process and everyone is different. Dr. Nava Greenfield of Schweiger Dermatology Group in NYC recommends that you should try a product out for three to four months before you determine whether it is effective or not. "Take before and after photos since the change may be too gradual to notice," adds Dr. Greenfield.
