have you stopped all the chemical and heat use? are you following the CG method? when hair is damaged you can just repair it, cause your hairs already dead, but you can help it along. hot oil treatments, deep conditioners and protein treatments can help, same people swear by it. i try to do a treatment once a week and follow it with a ACV rinse.
can you tell us more about your hair?
my hair: 3b, high porosity, high density and coarse hair (i think i finally figured that all out)
my hair loves conditioner only styling!
Oils and my own procuts are my hairs best friend
my hair goal length is bra strap length when curly.
