I've never read of results like this before! i'm so sorry.
1. I actually would caution against protein treatments right now since this could increase in the brittle factor. Go for moisture moisture moisture!
2. Shampoo with a gentle shampoo that contains some salt so that your can coax your curls back. I'd go for Giovanni Tea shampoo ( walmart and/or target).
3. do a hot oil treatment of olive oil and honey before you shampoo.
4. DC 1-2xs a week for the next 4 weeks. My honey child's olive you DC is AMAZING!!
Give it a month! I promise it will be better!
