It does what it says.
At my age, my hair needs care, especially after highlights and refills (hairdryer, general wear and tear, etc.).
It maintains the color shine, takes care of the hair, and overall, the combination of cream - mask - shampoo care gives the desired result.
Personally, having had a serious issue with my hair being burned at a hair salon and possibly due to age (I'm almost 50) and menopause, the hair did not fully recover even when I had to cut it very short.
In any case, I decided to turn to this specific company, knowing its quality.
And I am satisfied with the result of the overall care.
Of course, I will insist on this particular product (the whole range, cream, mask, shampoo) because I saw a tremendous difference in my hair and I can now do my highlights and dye without fear!

My girlfriend says she has never used a better mask in her life.
I have no opinion. I just insisted on getting the half-kilo economical package.

It offers amazing hydration and repair to damaged hair. The great thing is that you can use it even before dyeing or bleaching! You can leave the product on your hair for 10 minutes to lock in moisture. It doesn't affect the result afterwards and it protects damaged hair! I use this hair mask frequently because my hair was very damaged. I saw results from the first use.
It helps tremendously with frizz and blow-drying straightens in less time compared to other products. (I also use CHI KERATIN before blow-drying, it's also great) I highly recommend it, girls!
