Protein molecules polymerize with blow-drying or ironing heat and create large protein chains, preventing loss through cuticle breaks. Manageability, luster and moisture are noticeably improved immediately. Vegetable celamid and wheat proteins coat and smooth down broken, lifted cuticles for great manageability. NMF maximizes moisture retention and silk proteins seal cracked cuticles to lock in the NMF molecules. Silk PPT polymerizes with heat and forms a silk film to coat each strand, locking in vital emollients and nutrients.
