12 Hairstylists Reveal Their Favorite Products For Treating Thinning Hair

"One of my clients brought these SnobGirls Prestocure Bio-Serum Capsules ($17) to my attention and now I recommend them on the daily! I've seen them work miracles on thinning and brittle hair. Massage the solution from one capsule into freshly washed hair (from roots to ends), then blow-dry hair and style as usual. I've watched this product take clients from a fine and broken hairline to full and supple hair in just a couple weeks." — Velasquez
