Hey there! I use and like the SM Coconut/Hibiscus line, BUT it doesn't have hydrolized protein in it. (It basically means that the silk protein in the SM line is not as effective).

From what you describe, yes your hair probably needs more protein and you should probably add in at least an RO w/ hydrolized protein in order to maintain your protein levels in between PTs. Hope this helps!

EDIT: you can also get Colorful Neutral Protein Filler from Sally's and add a few drops to the SM conditioners you already have.
