Cryotherapy Frozen Hair Botox is a Brazilian treatment that works by freezing active ingredients inside the hair, locking them in for maximum effectiveness. This process delivers deep hydration, repair and strength from within. It reduces porosity, restores elasticity and leaves hair smooth, strong and shiny. Perfect for dry, brittle and chemically treated hair, including colored, bleached or straightened strands. The result: healthy, resilient hair with long-lasting nourishment.
