Hi there .. Im a newbie with 3b hair.

I wanna try this no-poo method but i am confused. this is what i use now...
Costco brand shampoo
Tresemme Moisture Conditioner
Tresemme Bouncy Curls Gel..
Aquanet Hairspray (i knowww sorrrryyyy thats why Im here!)

Then I use a diffuser to dry.. What do i need to eliminate to do the no poo method without eliminating my paycheck lol .. thanks in advance!!!
