If there were 6 stars, I would give them. I have been using it exclusively for the past 2 years. Besides the fact that it straightens my hair for much longer, it also nourishes and hydrates it. I don't compare it to any other product and I won't change it. The price is a bit steep, but it delivers maximum results

Amazing product. I have very frizzy hair. It was dull and damaged. The result after applying the product was immediate and spectacular. The frizz almost disappeared and the hair had intense shine. Instant hydration, subtle scent. It's like water and it doesn't stick at all on the hands. I have long hair and with 3 washes per week, it lasted me a little less than 3 months (application from the middle of the hair and below, not at the roots). It goes without saying that I will buy it again.

Incredible product, you put it on your hair and then straighten it and there is no frizz. I have thin hair that frizzes and this has saved me.
