I would just try one bottle of the curl booster.
Jessiebanana & Lauraimes: I will try not to be afraid again... but it's just that I easily get frizz, and I don't need more of that (I'm also avoiding humectants now, but that's also because our dews are around 65 now). I think I am scared that my hair will gradually get worse, not at once, and that I won't be able to notice myself what the thing causing the bad results would be... I guess that's why I trying to avoid almost everything people have problems with, although that seems to be quite impossible.
I promise I will use the curl booster tomorrow
. (I've had 2-3 weeks of KCCC experimenting, so now I can use another thing again without experimenting too much).
