Many of us have returned from holidays with dry, brittle hair-weeks of swimming in the ocean, chlorinated pools and sun exposure snapping all the lustre from our locks. Leave-in conditioners and treatment creams can offer temporary relief, but nothing revives the hair like a hit of Nanokeratin. Tiny molecules of keratin are deposited on the hair strand, repairing the damaged sections. Perfect for colour treated hair. One treatment will get the hair feeling smooth and looking better, but some serious head cases (over-bleached blonde hair) could require up to four treatments. A treatment costs $75-$125 depending on the hair length and salon.
