I'm also in the Bay Area, not quite as coastal as SF, and this week the dews are abnormally high because of the heat and recent rain. Dew point here today is 67. Normally we fall into the optimal range all the time. So if your hair is wigging out and frizzing more than usual, it may get better in the next week or so. I'm just mentioning this as an additional issue to what others have brought up already.
Former longhair, now CG, living in N. California where the fog meets the wind
3a/b, fine, normal porosity/elasticity, high density
Conditioner wash and style. That's it!
