The best , and perhaps easiest, way to patch up damaged cuticle layers is simply through light protein conditioning. Protein fills in gaps, binds to damaged places, and mends individual exterior scales along the cuticle. Regular protein conditioning improves the hair’s porosity by reinforcing the cuticle layers and allowing the hair shaft to better hold on to the moisture it is given. You don’t want to get too excited with the protein though because this can make the hair even drier. Kalea Passion Conditioner, is good for shoring up the cuticle damaged. Some porosity problems can be temporarily resolved by applying a low pH solution or product, usually a conditioner.  At the salon we highly recommend Kalea Passion Conditioner.
