What are hair bonds?

Hair bonds are chemical links, which connect the hair’s proteins, and they are crucial to maintain its strength, shape, and suppleness. These bonds are easily damaged by chemical treatments like bleaching, colouring and perming, as well as heated styling tools, and harsh shampoos. Even washing hair with water that is too hot can weaken the bonds and make them more vulnerable to breaking. Hair with broken bonds is dull, dry and frizzy, and prone to split ends and breakage. Repairing damaged bonds restores the hair’s strength, suppleness, smoothness and shine.
