Hi, i'm fairly new to all this. i always assumed that i
was protein sensitive but now i'm wondering.... i
based it on the fact that i have low/med porosity,
my hair is med/coarse and very dense plus no damage...i have never colored my hair or used heat...so i was
guessing i didn't need protein...now i'm wondering if maybe i do sometimes..so...

is there a quick cheap way to test how i respond to a protein treatment? Once i try a PT do i need to do a DT or wait and see how my hair responds to just the pt?

If Im protein sensitive my hair will get dry and like straw correct?

Thank you!
