Frequently asked questions

Questions about the Repair Shampoo? Find our most frequently asked questions here. Still need help? Contact us.

What does this shampoo do for my hair?

It gently cleanses while actively working to repair damage and strengthen weak hair. The nourishing oils in the formula help rebuild hair from the very first step of your routine and protect it from further stress, so hair feels softer, stronger, and healthier over time.

Can I use this shampoo every day?

Yes — it's gentle enough to be used as your everyday shampoo, similar to how you'd use any regular shampoo, while still providing repair benefits with each wash.

Will this help if my hair is damaged from coloring or heat styling?

Yes. The Repair Shampoo is specifically formulated to help hair that's been weakened or stressed by processes like coloring, bleaching, and heat styling, working to rebuild strength and protect against further damage.

Do I need to use the Repair Conditioner too, or is the shampoo enough on its own?

While the shampoo offers repair benefits on its own, pairing it with the Repair Conditioner (and periodically the Repair Mask) gives you the most complete routine — the shampoo cleanses and begins repairing, while the conditioner and mask add extra moisture, softness, and deeper strengthening.

How soon will I notice a difference in my hair?

Many people notice hair feeling softer after just the first wash. With consistent use over several weeks, you'll typically also notice improved strength and reduced breakage as the repair benefits build up over time.

“My hair felt stronger and noticeably healthier after just a few washes. The Repair Shampoo leaves my blonde soft, shiny, and much less fragile. Absolutely love it!

The Science

A synergistic blend of skincare actives and superfoods

Ceramide NG

A clinically proven skincare active, ceramides repair the structural integrity of hair by sealing the cuticle, locking in moisture. Less damage and breakage, better colour retention and resilience.

Argan Oil

Known as ‘liquid gold,’ argan oil is rich in linoleic acid and vitamin E, replenishing the fatty acids and moisture stripped by bleach and colour to make blonde hair softer, shinier, golden.

Our synergistic superfood complex is hydrolyzed for better absorption, delivering amino acids directly to the hair fibre to reinforce it from within for more resilient, elastic blondes.

Chickpea Extract

Our synergistic superfood complex is hydrolyzed for better absorption, delivering amino acids directly to the hair fibre to reinforce it from within for more resilient, elastic blondes.
