As I get older, my hair is the first thing that shows. I didn't really worry about the thickness of my hair before, but at some point, my hair roots started feeling weak and my parting looked wider, so I started hating looking in the mirror..! Lately, I've been looking around for hair loss clinics, and since the reviews for Gangnam H.O.O. seem good, I'm thinking of getting a consultation. If anyone has been there, please share your honest review~ Also, besides hospital treatment, I'm wondering what I should take care of in my daily life. Do you recommend biotin?
