12 Hairstylists Reveal Their Favorite Products For Treating Thinning Hair

"The Phyto Phytolium 4 Densifying Scalp Treatment ($69) has been my favorite treatment for clients that have thinning hair. It uses plant- and fruit-based oils and extracts to replenish locks and stimulate healthy hair growth, along with active ingredients that create micro circulation in the scalp, strengthening the hair bulbs. You can maximize your results by using it three times a week for three months." — Xavier Velasquez, stylist at the Serge Normant at John Frieda Salon in New York
