BKT Nano Pro Nanoplasty™ is our next-generation smoothing system, a formaldehyde-free, vegan, and deeply restorative treatment designed to straighten, repair, and rejuvenate your hair from within. Unlike traditional keratin or chemical straightening, Nano Pro works through a bio-active infusion powered by nanotechnology, delivering nutrients, organic acids, and botanical actives directly into the hair’s inner core for results that feel light, natural, and luxuriously smooth.
