If I'm using the right products I have the best curl formation out of the shower and I have very dense hair. Four things give me shower frizz.

1. Too much protein.
2. Build Up
3. Dryness...usually caused by trying to get rid of build up
4. If I stay in the shower too long *after* rinsing out my conditioner. I think my hair just gets too much of a good watery thing.
