About 6-7 months ago i did two protein treatments in my hair and did not properly care for my hair after so i received some damage. Now my hair isnt sensitive to proteins, but due to me not properly moisturizing it i develop really dry brittle hair that had lost its curl definition towards the roots. I was able to get my hair back moisturized and healthy after changing my routine a little. Yet about 3 inches of my roots still have no definition while the rest of my hair is 3b-3c. How can i revert my curls? Or do i just have to just let it grow out with time? please help me!
