The Pro-Keratine Complex seems to work well, with hair feeling less brittle and more resilient after styling. Several people observed that their hair had a healthier appearance, with fewer split ends and overall damage.

The fragrance is subtle enough to not overwhelm, yet it provides a pleasant scent that lingers without being too strong. For those who appreciate floral notes, it adds a nice touch to the overall experience.

For others, the scent proved to be overpowering. Some found the fragrance too strong and mentioned it clashed with their personal preferences or other hair products they were using.

This makes it ideal for people who want smooth, healthy-looking hair without the greasy or heavy feeling that other serums may leave behind. It’s perfect for anyone looking for a light, non-oily heat protectant.

While the lightweight texture is generally appreciated, some users found it insufficient for their thicker or more coarse hair. They felt that a more robust formula would provide better nourishment and moisture, especially when dealing with frizz or dryness from frequent heat styling.

Consistency Across Batches
