If you do a protein treatment, be sure you follow with a deep treatment the same time. You could try Curl Junkie's Beauticurls which has both protein and conditioner in it and follow it with a deep treatment. That way, you are getting a limited amount of protein and lots of deep conditioning to offset coarseness.

If you use other products, don't leave in the protein treatment for too long and leave in the deep treatment a long time. Hope that helps!
2/c and some 3A.
Protein sensitive but can use occasionally
Highly porous. Color over grey.
Best 1st day method: Super Soaker
Stylers: Mix Curls in a Bottle into everything for shine. Terrible pj
Sometimes try roller sets - classic glamor but I prefer my curls.
Every day is a gift
