ive wondered about this as well, cause when i started using aloe vera my hair LOVED it but after awhile, it made my hair all icky, like what protein does. but i find it ok when ive mixxed it with oil or somthing like that then use it my hair seems to like that

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.
