Knowing how to repair damaged hair is the difference between hair that just looks coated and hair that is genuinely stronger. Heat styling, colouring, and Dubai's sun and hard water break the internal bonds that keep strands elastic — so the real fix is a bond-building routine, not just a richer conditioner. This guide walks you through how to repair damaged hair step by step, compares the two leading systems (K18 and Olaplex), and lists the exact products with live AED prices.
What causes damaged hair?
Bleaching and colour break disulphide bonds; flat irons and blow-dryers erode the cuticle; chlorine, salt water and hard water strip moisture. The result is breakage, split ends, frizz and dullness. Repairing it means rebuilding those internal bonds and then sealing the cuticle.
How to repair damaged hair, step by step
1. Rebuild bonds with a molecular treatment
Start with a leave-in or rinse-out bond builder. The K18 Leave-In Molecular Repair Hair Mask (50ml) (AED 273.00) reconnects broken keratin chains in four minutes, while the Olaplex No.0 Intensive Bond Building Treatment (AED 105.00) and Olaplex No.3 Hair Perfector (AED 104.30) rebuild disulphide bonds before you shampoo.
2. Wash and condition without stripping
Swap harsh cleansers for bond-safe care such as the K18 Damage Shield Protective Shampoo (AED 174.00) to protect colour and strength between treatments.
3. Seal the cuticle with a repair oil
Finish with a lightweight oil to smooth and shine: the K18 Molecular Hair Oil (AED 289.00) or Olaplex No.7 Bonding Oil (AED 115.50).

Frequently asked questions
Can you really repair damaged hair, or just hide it?
You can genuinely repair it. Bond-building treatments like K18 and Olaplex reconnect the internal bonds that heat and colour break — not just coat the surface.
How often should I use a bond-repair treatment?
Most people use a leave-in like K18 every few washes, and a rinse-out Olaplex treatment weekly, adjusting to how damaged the hair is.
Is K18 or Olaplex better for damaged hair?
K18 is faster and leave-in; Olaplex is a step-by-step regimen. Many people use K18 for quick repair and Olaplex shampoo and conditioner for maintenance.
