i kinda have this problem as well, though not just my ends. do you low poo? i do and i think that its cause the poo washes the natural oils out, cant really be helped i dont think, cause has to get rid of the dirt n that. maybe if you pre poo? i message my scalp with a rosemary oil mixture n that seems to help.

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.
