i know the feeling, and ive noticed th only thing you can do is please your own hair, i research everything before i put it in my hair, and with that i can see if its going to help what its going to do etc. for me thats been the only way i can find stuff out

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.
