Hairdressing Injury, Support & Information

Hairdressing injuries can range from slight cosmetic damage to severe chemical burns that cause permanent scarring; the chemicals used to change the colour and the texture of hair, if misused, can be dangerous and leave a person in a position where they do not know what to do or how to measure the damage caused.
