Honestly, it is one of the best products I have ever purchased. My hair was severely damaged from black dye on a light balayage. After an indifferent treatment at the hair salon, my hair became dull, fragile, lifeless, and overall a mess. From the first application of Olaplex treatment, my hair appears fuller, more vibrant, with movement and shine! Now, after two months of use, it's as if my hair has never been damaged! Compliments are pouring in, truly. The price is a bit steep, but it's worth 100%. Of course, I will buy it again and invest in the rest of the products in the range!

Tremendous difference from the first use. My hair was literally burnt from the consecutive decolorizations. I had some treatments at a hair salon with a similar product from another company, but the difference I see with Olaplex is incomparable. As for the price, it's worth it because a salon treatment costs over €30. Even so, with 100, you can get 6-7 treatments, while at a salon, you would need double that. The use at home is very easy, it doesn't require any specialization, it's like applying a hair mask. Personally, I doubled the times for better results and it was indeed effective. My hair became softer, appeared less dry and brittle, and even 5 days after washing, with styling products on, I managed to comb them and they were still smooth! If needed, I will definitely purchase the same product again!

My damaged hair has been saved from highlights. So far, I have done 3 treatments (one per week) and the difference is huge. I used to need 10 minutes to detangle, but now with one stroke, my hair is detangled and doesn't hurt. I have long wavy hair with very fine strands. The curl has become more defined and breakage has significantly reduced. I also purchased number 9, which helps prevent frizz.

The treatment is truly a treatment, I saw a huge difference in my hair... It is the second time I buy it and definitely not the last.

Awesome product! It has changed my hair!! From being prickly, they have become soft and don't break easily. I use it for coloring and as a treatment
