Does it smell nice? Yes. Does it leave the hair moisturized? Sort of. Is it easy to use? NO.

I have long hair down to my waist and thick with coarse strands. I made the mistake of balayage and it is completely fragile, so I decided to invest in the company's line for hydration.

It's a struggle to do the 2nd step of the line with so much hair! I started normally with shampoo number 1, all good. I towel-dry my hair, I dry it, I move on to the 2nd step which is this treatment. First of all, whoever said you need max 100ml probably has much less hair than I do. Personally, I needed 220ml and the bottle is 300ml, so it's already unprofitable. There's no way that it won't fall more on the strand and then dry properly without leaving residues. I tried to apply it as thinly as possible, I applied the treatment with a brush and then combed it through to remove the excess. Because the treatment doesn't hydrate or soften directly and because the 1st shampoo opens the cuticles, with the combing, half of my ends broke off and stayed on the comb.
After I went through the ordeal of covering all the hair, I left it for 30 minutes to take effect. I grab a hairdryer, I see that there's no way it's going to dry because too much product has fallen, so as it says in the usage instructions, I do a light rinse, just enough to remove the excess, I grab the hairdryer and start. They did not want to dry at all! The water along with the treatment made them muddy. After 50 minutes with the hairdryer and once everything dried, I straightened it at 170 because the 130 didn't even accept the hair. All nice, shiny, somewhat soft but very heavy, you couldn't run your fingers through it and it left a slime on your hands (and wherever you touched), which while it wasn't visible, you could feel it and had to wash your hands immediately. Very heavy treatment. I washed my hair the next day (28 hours later, I couldn't stand it any longer) and I used shampoo number 3 and the mask for 10 minutes. I rinsed, dried, straightened. Much better and more immediate.

In my opinion, since the whole line costs quite a bit, it's better to invest in Botox express rather than in numbers 1 and 2. Go straight to shampoo number 3 and the mask. Number 4 is unnecessary, all leave-ins are the same.
