Keratin Hair Constructor 3in1 Spa Master Keratin Line

I purchased this product a year ago. It is very thick. I decided to dilute it with a thermal conditioner. The effect is really good when used in this way.

I will leave a new review. After thorough testing, I tried applying the product in a sufficient amount and sealing it with a flat iron as instructed. It styles hair perfectly, without making it sticky or heavy. It straightened my hair, yet somehow it still remained voluminous. However, after washing my hair, all the effects were washed away. There is no talk of weeks of styling, as stated in the description. Then I started applying it in tiny amounts and styling with a blow dryer/flat iron. It styles beautifully and provides heat protection. The result is similar to a styling mousse, but better.
