Shampoo then conditioner.
Shampoo first ! Then you need a good Redd Foxx soap !
I condition first and then shampoo. It makes my hair feel and look fuller without the conditioner weighing it down.... (:
It has usually been shampoo and then conditioner. But there has lately been a trend toward doing just the opposite, and I recently saw a commercial for a new product specifically designed to be used that way. Who knew? :)
Shave your head. Then you won't have to worry about either.
I just use shampoo.
