i agree with you i think thats the reason y i dont really use products..... its not just the hair industry its the beauty industry in particular. think about a massive line: make up, anti aging etc. its all the same, they'll just change one or two ingriedients so that it smells different or that theres a different "working product" in it. then they'll sell it with a "whole new formula" or a "cream" im only young but i stay away from all that stuff, n stick with my good old oils that do the same thing as somthing that you could pay 300 + for.
just my 2 cents.

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.
