About every three days. I just don't want to wash it more than that, so I'm learning how to make it look decent in between washes.
3a/b, F, normal porosity
Wash with either Suave Tropical Coconut, As I Am, or CJ Daily Fix
Condition with STC or Yes to Blueberries and detangle with Denman, rinse very lightly (baptismal rinse)
Add LAL gel, either Sport or Wet Look, scrunch with flour sack towel, and plop
Diffuse 5 minutes, then air dry
I cowash weekly and shampoo once a month or as needed- which ever comes first. I can't exclusively cowash because my hair gets weird and dull and my scalp gets just itchy and nasty. But I can go at least a month with no shampoo.
Have you tried doing brown sugar scalp scrubs? They really cut through scalp buildup well. Just add 1 tablespoon of brown sugar to the conditioner for one co-wash, then give yourself an extra good scalp massage with it.
Baby Fine 3B, low porosity, normal density and elasticity
