I just quickly caught the part of the episode with the woman who had grey hair and super frizzy hair, and I saw that hairstylist used a treatment to "chill out" the woman's curly hair.

I was wondering what treatment she used on her hair, does anyone know? I didn't catch it if they mentioned it on the show.

I just happen to have pretty much exactly the same unmanageable frizzy hair and I wanted to know if the treatment she used on her was available elsewhere and if I could find out more about it.

Thanks!
