My hair can't get enough protein. A few of my favorites:
Rinse outs (can also use as LI)- ION Effective Care (at Sally's), Regis Olive Oil (Regis salons, including the ones in Walmart)
Leave-ins: Cure Care (at Sally's)
Protein Treatment: I use IAGirl's gelatin PT, with an extra protein boost (3 packets of gelatin instead of 1, 3 different high protein conditioners, plus the other regular ingredients, either under heat for 40 minutes or blow drier method). Another option is Aphogee 2 step- it's the same type of protein as the gelatin treatment, minus the mixing, but it does have a pretty strong odor, which is why many of us started using gelatin instead.
