Product Description
Natural Formula Keratin Intense Serum is a professional hair care treatment designed specifically for hair that has undergone chemical straightening treatments or frequent heat styling.
These processes can weaken the hair fiber and cause dryness, loss of elasticity and reduced shine. The advanced formula helps restore the hair’s strength and softness while protecting the results of straightening treatments.
The serum contains pure keratin with a dual-action repair system that helps rebuild the internal hair structure while forming a protective smoothing layer around each hair strand. This protective layer helps maintain smoothness and manageability while enhancing shine.
Enriched with Panthenol (Pro-Vitamin B5), the formula helps strengthen the hair fiber and improve resistance to heat damage, chemical treatments and breakage.
Moisturizing ingredients and gentle conditioning agents help smooth the hair surface, protect it from environmental stress and make styling easier without weighing the hair down.
After use, hair appears smoother, stronger and shinier, with improved softness and flexibility.
