Customer reviews
What customers say: This treatment is widely praised for making severely damaged hair feel significantly stronger, softer, and healthier, especially when used with N°3. Some find the application messy and don't see dramatic results.
★☆☆☆☆
Waste of time and money
This product did absolutely nothing for my hair, even when I used it exactly as directed with the N°3. My hair still feels just as dry, brittle, and prone to breakage as before. I followed the instructions carefully, but saw zero improvement. Very disappointed with the lack of results.
★★★★★
Stronger hair now
My hair feels less fragile and looks healthier after using this.
★★★★★
Restored my hair's health
My hair was severely damaged from coloring and heat tools, feeling dry and breaking easily. Using N°0 as a primer for N°3 has truly transformed it. It’s now much smoother, stronger, and has significantly less breakage. This treatment has restored my hair's health and vitality, making it look salon-fresh.
★★★★★
Excellent bond repair
This pre-treatment genuinely works to repair hair bonds. My hair was really damaged from bleaching, but it's much stronger and smoother now thanks to this product used before N°3.
