i developed alopecia 2 years ago: i had three 4cm patches at the top. all grown back, still slightly shorter than my longest layer one silver streak (not grey!) the problem is that my normal hair is dry thick and slightly prone to frizz, my new growth is fine, wiry, frizzy and weirdly oily i am using the kerastase elixir after lush shampoos. this is fab on my normal hair. any ideas?
