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!

I love all the Curl Junkie products. Still experimenting with gels and curl creams. Still hoping for 2nd day hair....
