In life, opposites sometimes attract.

In hair color, they always do... and that’s what leads to staining around the hairline. Most hair color has a positive charge(+), while hair has a negative ionic charge (-). This is what helps hair color stick to your hair. But our skin, like hair, has sites that are negatively charged, so hair color is attracted to skin as well... and you’re left with ugly stains! That’s why +Repelle™ with positively charged Pretectin-22™ has dual-action:

First, +Repelle is attracted to the negatively charged sites in skin, neutralizing them and creating a physical barrier to the hair color;
And second, it actually repels the positively-charged hair color itself.

With +Repelle, you’ll get rave reviews about your hair, not the stains on your hairline!
