## Customer Reviews

### ⭐⭐⭐⭐⭐ De fácil aplicación
*by C***P on August 15, 2024*

Es de muy fácil aplicación con Un resultado perfecto..

### ⭐⭐⭐⭐⭐ natural-looking straightening
*by B***L on April 1, 2025*

The product is quite thick. I noticed the difference from the first application. I followed the product application instructions; they are clear. It doesn't have a strong scent. It leaves hair very soft. It's not an extreme straightening agent; it softens curls and waves, leaving a natural-looking straightening.
