Thanks for the reply!
I actually live in a drier climate--not too humid. Our dewpoint generally does not get higer than mid-50s or so, with some exceptions. My hair is definitely reacive to humidity (you should see it when we travel to the beach...agh!) Does glycerin make frizz worse?
I'd say my hair has high porosity--it definitely seems dry and I do highlight with bleach. I also use a lot of gel to get the look I like, so that may affect things too. Up until now, I've always used Pantene Curl S and C.
Do you think I should start out trying a cowash? Or should I go straight to a low-poo option?
