    Hair damage is caused by everyday stressors like heat styling, colouring, chemical treatments, UV exposure and environmental factors that weaken the hair’s internal bonds.

  • What is a bond repair treatment?

    A bond repair treatment is a targeted formula that works inside the hair fibre to rebuild broken bonds, strengthen strands and restore softness and shine.
