My hair was bleached and frizzy. Literally dry as straw. I went to megacon and a sweet lady taught me how to use a hair stick and made me promise to try this. She was a literal Angel. It has transformed my hair. Wish I had known about it before I started bleaching.

A must for chemical treated hair
Best leave in hair mask, I have bleach process hair. I been using this mask for about 5 years now. So worth the price. It was helped strengthen and keep my hair strong after bleaching for years.
