I have 2b/2c hair. I currently use devacurl lowpoo. My day two hair is oily/greasy at the roots.
Do I switch to a cowash? I have fine/low porosity hair, but a lot of it. I'd love to go 3 or 4 days between washes because it takes my hair a really long time to dry.
I would try using a dry shampoo, here's a list of some good ones for curly hair: https://www.naturallycurly.com/curlreading/wavy-hair-type-2/top-15-dry-shampoos/
