Frequently Asked Questions
Is it necessary to have a smoothing to use this product?
It’s not mandatory, but highly recommended. If you have frizzy, dry or difficult to tame hair, this conditioner will help you achieve a much smoother and polished finish even without chemical pretreatments.
How is it different from Maca Care conditioner?
While the Maca Care line focuses on moisturizing and volumizing with collagen, the BNC Keratin Conditioner Conditioner focuses on structural reconstruction and smoothness control, being more effective in closing the cuticle and eliminating stubborn frizz.
How do I know it is the original Karseell product?
In our Official Website we guarantee that you receive the 500 ml bottle with the seal of authenticity and the original professional formulation. Imitations often lack the real concentration of keratin needed to protect your straightening.
Can I use it if I have colored hair?
Yes, keratin helps protect the fiber after coloring, keeping hair strong and preventing split ends and brittle ends.
