Hello flower,
I do not have pics really... my fotki does not show how thicker my hair got . but i can feel and see the difference with different techniques.
The first link is a discussion on how to go from fine to think. The second link is a very long thread about thin hair.
techniques:
airdrying
stretching relaxers (if your relax)
not relaxing bone-straight
castor oil
use less heat
deep conditionning
protective styles
avoiding dominican blowout.
