Hi - I don't have that issue, but you might want to consider using a mild sulfate shampoo at this time. I like Deva Lo Poo and No Poo but when my hair gets very greasy I use a mild drugstore shampoo with sulfate.
I know if you are totally cg it may seem like going over to the dark side
but you could try it once and see how you feel about it.
2/c and some 3A. Modified CG.
Highly porous. Color over grey.
Best 1st day method: Super Soaker
Conditioners: Curl Junkie Beauticurls Strengthening Conditioner,
Deep condish: Curl Junkie Curl Rehab
Stylers: Experimenting with cones & sulfates while the dews are high. Sometimes try roller sets - classic glamor but I prefer my curls.
Every day is a gift
