FAQs
Repair Duo Jumbo Size

Who is the Repair Duo best for?
This duo is formulated for damaged, overprocessed, or chemically treated blonde hair. It's ideal if your hair feels weak, brittle, or prone to breakage.

Why is this a 32 oz jumbo size?
The 32 oz (946 mL) format is our largest size, designed for salon professionals or at-home use for those who want a longer-lasting supply without repurchasing as often.

Will this weigh down fine or lightweight blonde hair?
No. The formula is designed to repair without heaviness, so hair stays strong and resilient without feeling greasy or weighed down.

Can I use this if I also use a toning shampoo (like Violet or Blue)?
Yes. Many people alternate the Repair Duo with a toning shampoo throughout the week to balance strength needs with brass control — repair one wash, tone the next.

Is this safe for color-treated or chemically lightened hair?
Yes. It's specifically formulated for damaged and overprocessed blonde hair, and it's free from sulfates, salts, parabens, formaldehyde, MI/MCI, gluten, and animal by-products.

Frequently asked questions

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

How often should I use the Repair Shampoo and Conditioner?

You can use the Repair Duo as your regular everyday shampoo and conditioner, or a few times a week if you're rotating with other products. If your hair is especially damaged or dry, using it consistently with every wash will give you the most noticeable repair benefits over time.

How soon will I see results?

Many people notice hair feeling smoother and softer after just the first wash, since the conditioner works to detangle and soften immediately. Deeper repair benefits — like reduced breakage and improved strength — build up with consistent use over several weeks, similar to most repair-focused hair care products.

Is this safe to use on color-treated or bleached hair?

Yes. The Repair Duo is designed to work well on color-treated, highlighted, and bleached hair, helping to counteract some of the damage that coloring processes can cause. It's gentle enough for regular use without stripping or fading your color treatment.

Who is this product for?

The Repair Duo is made for all hair types and hair colors, not just blonde or highlighted hair. If your hair feels dry, damaged, brittle, or prone to breakage — whether from coloring, heat styling, or everyday wear — this duo is designed to help restore its strength and smoothness.

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

Yes — the Repair Duo is formulated specifically to target damage from processes like coloring, bleaching, and heat styling. It works to rebuild hair strength from within and reduce breakage, so hair looks and feels healthier over repeated use, rather than just masking damage temporarily.

“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!

— Rosa H.

The Science

A synergistic blend of skincare actives and superfoods

Ceramide NG icon describing Blacklight Blonde Science hair products

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.

Lentil 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.
