What Causes Hair Damage?

Before learning how to fix damaged hair, it’s important to understand what weakens the hair fibre. Common causes of damaged hair include:

• Heat styling and blow drying
• Hair colouring and bleaching
• Chemical treatments
• Hard water exposure
• UV damage and pollution
• Lack of hydration
• Overwashing and rough handling

Damaged hair often appears:

• Dry and rough
