Frequently Asked Questions

In simpler terms, what does MBC do?

MBC was created to repair, restructure and maintain a healthy "disulfide bond." This bond is damaged during the color, lightening, perming, really any chemical process done to the hair. When it is added to a formula or used as a stand alone treatment it not only maintains the integrity or strength of the hair shaft it actually repairs and rebuilds the "Disulfide bonds" that have been broken down by the chemical process.

It works from the inside out...from the cortex to the cuticle of the hair shaft.
