yep i had that problem as well, wat i did was wash it with shampoo, (i still felt terrible although it was no sulfate!!) detangled in the shower, blotted dry, n i added a curl defining hair cream, sealed the ends with argan oil and left it to air dry. hardest part was NOT TO TOUCH! im horrible at that, but when you manage to keep ya hands off it, its worth it. then when i woke up, i wetted my hair, put more of the curl cream in and sealed the ends. i was really surprised, cause i never had had nicer curls before

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.
