Users also appreciated the minimal preparation required compared to salon treatments, making it a convenient at-home solution.

Longevity of Results
87%
The treatment's long-lasting effects were widely appreciated, with many users noting that their hair remained straight, shiny, and frizz-free for several months. The results lasted even beyond the advertised 4-6 months for many, making it a great investment for those who don’t want to redo their treatments frequently.

Hydration & Softness

While most users found it worth the price, a few felt that the treatment didn't justify its cost.
