Holy grail product

5 stars out of a maximum of 5

Believe every amazing thing you read about this product, it genuinely works. I suffered with stress hair loss last year, when the hair stopped falling out 4 months I go bought this to see if it would help save my hair, and it certainly has! My natural hair has never been so long and thick, it’s mind blowing. Every time I see people they comment on how long it is. Honestly worth every penny, will never stop raving about it.

Game changer

5 stars out of a maximum of 5

This is definitely a brilliant invention. Just with 4 uses it managed to restore the life in my bleached damaged hair. Just an advice, after the 4 minutes I suget to apply a mask or conditioner and rinse after. The product needs only 4 minutes to work and after you can use a mask and rinse it

Expensive but a luxury

4 stars out of a maximum of 5

It is expensive but I can't complain because it does help my blonde hair look a lot healthier . I accidentally ordered the wrong size I think so was annoyed but I just love how it feels and what it does to my hair .

healthy locks

5 stars out of a maximum of 5

i thought this was overhyped but after trying this... i already see a major difference after 3 washes! my ends feel so healthy again after years of bleach damage & frequent hair dye. abbey yungs suggestions never disappoint! my hair is pretty fine & short now, but i feel like with using this my hair will finally grow longer without breaking off after a week :)

Miracle worker

My bleached hair was always so hard to manage never looked shiny or nice until using this product. I use it every 3 washes. Leaves your hair smooth and you can feel the damage repair. Make sure to condition after the 4 minutes is up.

Amazing for coloured hair

I love using this mask, I feel it really helps my fine coloured hair stay in good condition and doesn’t weigh it down.

Excellent

5 stars out of a maximum of 5

Love this product, it’s the only way to keep my blonde highlighted hair healthy. I’m a natural mid-dark brunette and use heat on my hair 3x a week so it definitely needs the broken bonds replacing.

Amazing

This product really saved my damaged bleached hair after a disaster hairdresser appointment! It’s so good I had to buy the smaller size for travelling

Great treatment

5 stars out of a maximum of 5

This is a great treatment for your hair, it is soooo expensive but I don’t use it often and you don’t need to use a lot. I use it after shampooing in the shower then wait until the four minutes are up and carry on with the rest of my hair care routine
