Juvexin restores hair from the inside out, returning it to a more youthful state. Juvexin is nonhydrolyzed, contains intact keratin and consists of both large and small molecules. The smaller Juvexin molecules penetrate the cortex, improving and restoring hair from the inside out while the larger molecules wrap around the cuticle layer of the hair, creating a protective shield against free radicals such as UV Rays and pollution. The GK Hair Hair Taming System with Juvexin is beneficial to all hair types.
