It does seem like watching paint dry. But I joined the Grow Out Challenge 2008 -- not to challenge my hair to grow, but to be conscious of its growth (measuring monthly, regiment, etc.). And it's growing. Before this I didn't notice a difference. Also if you hair is getting curlier, the curls are hiding any new length.

Playing with my hair is a hobby. Fluffy, fine natural 4a. Goal= Healthy, beautiful hair that retains its length.
Hear that crash? It's me falling off the CG wagon.
