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.

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.

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.

Ive noticed less breakage since adding this to my routine. Hair feels clean but still soft.

My hair was super dry from bleaching and this has helped alot. Feels healthier after every wash.

My hair feels alot stronger since I started using this. Doesnt leave it feeling dry like some repair shampoos.

My hair feels stronger

I have a lot of damage from years of highlights and heat. Been using this for a few weeks and my hair already feels stronger and not as rough.

Noticed less breakage

I've been using this for about a month now and my hair feels much healthier. I also notice less hair breaking when I brush which is a big win for me.

Cleanses my hair and hole leaving it soft and healthy! Love the smell

So far so good! My bleached coarse hair likes it

New favorite shampoo

My hair has been through A LOT lol. Color, bleach, heat... everything. This cleans really well but still leaves it feeling soft and healthy.

Really good for bleached hair

My blonde was getting pretty fragile and dry. I've been using this every wash and can definitely feel a difference, especially on my ends.

Nice everyday shampoo

I like that it cleans without making my hair feel dry or tangled. Haven't noticed a huge change in strength yet but overall my hair feels really nice.

Gentle but actually cleans

I was worried a repair shampoo would feel heavy but not at all. My hair feels really clean and soft after without that stripped feeling.

Good so far

Only been using it for a couple weeks but my hair definitely feels softer. I'm hoping to see more improvement with the damaged ends over time.

Didn't expect much from a shampoo

Honestly I usually rely on masks for repair but this surprised me. My hair feels softer right after shampooing and seems way easier to manage.

Love this for my bleached hair. It feels softer and way less brittle after washing.

Great for my fine hair

I have fine damaged hair and this doesn't weigh it down at all. Been using it about 3 times a week and really like how my hair feels.

Really nice shampoo and you dont need much. My damaged ends have been feeling so much better.

Super Effective

It leaves my hair clean, nourished, and soft without irritating my sensitive scalp.

Salon Results

My hair was dull and brittle from heat styling, and this shampoo brought it back to life.

Perfect for my damaged hair

Finally a repair shampoo that helps my damaged blonde hair without weighing it down. My hair feels healthier, smoother, and much easier to style after every wash.

My hair finally feels healthy again

I�ve been using this shampoo for a couple of weeks and my hair already feels softer and stronger. It cleans really well without drying it out, and I�ve noticed less breakage.

Thank you so much for your kind words! We appreciate the feedback and positive review!

Less breakage

My hair feels stronger and I�m seeing way less breakage when styling. It�s gentle but still leaves my hair clean and soft.

Love to hear that you are happy with the results of our Repair Shampoo! This is amazing, thank you so much!

Stronger Hair After Just a Few Washes

My highlighted hair was feeling weak and dry, and this shampoo made such a difference. It cleans gently while leaving my hair softer, shinier, and noticeably stronger.

Soft, smooth, and easy to manage

Really impressed with this shampoo. My hair usually feels rough after washing, but this one leaves it soft and much easier to detangle
