Usually I shampoo daily and condition 1-2x per week, but right now I'm experimenting with some new products so I'm not following my regimen as strictly.
Hair type: 4a
I wash and deep condition (sit under dryer for 15 min) once a week. If I'm wearing a puff I wet my hair everyday and put conditioner on it.
Hair type: coarse, kinky 4a
Daughter of OS, 4a/F/iii watch spring sized double processed curls.
I cowash every other day, wet hair every day, never use shampoo
Clarify hair once a month with baking soda, usually right before deep conditioning.
Fall/winter/spring--shampoo once a week
Summer-shampoo at least twice a week. A conditioner wash in there too. Basically my hair is rinsed in some way at least 3X a week in the summer. It's too hot not to!
