you could always add protein to your favorite LI. I just got neutral protein filler from sallys....and WOW my hair LOVES IT!!!!! I actually applied several drops to CJ repair me...left that on 10-15 mins...rinsed and then added couple drops to KCKT...My hair shrunk 2-3 inches...and clumped up quite nicely..which for a wavy is a miracle...so this NPF you can do as a treatment directly to your hair or by adding it to products which boost the protein amounts...Good Luck
