We've noticed that we tend to get Emailed about the same semi-perm hair color questions over and over again. So here's list of the most frequently asked questions, and our answers, about semi-perm hair dye.

NOTE: These questions are answered from our extensive experience and from the experience of the many customers and friends we've talked to about semi-perm hair colors. We're not professionals, please consult a professional if you need really hard core educated advice.

How long will the colors last on my hair?

It's not possible to accurately determine how long a color will last on each person's hair - it depends on how damaged your hair is, the starting color of your hair, and how bright/dark of a color you're using. Generally semi-perm hair dyes will last 4-6 weeks and may not rinse completely out of bleached or light hair.

How light can a Semi-perm color make my hair?

Semi-perm colors do not lighten hair. Only a hair color that contains peroxide or a bleach can lighten hair.

Think of a semi-perm color as cellophane, generally it just darkens whatever's underneath or adds vibrant color, but doesn't lighten (yellow cellophane and other bright opaque colors do not figure into this analogy)

I've bleached/streaked/colored my hair before, how long will this take to rinse out?

Like the above lasting question, it's anyone's guess. But the more chemical treatment your hair has been through, generally the longer the color will last.

Sometimes you will find that your hair is so damaged that color *doesn't* stick well in your hair. In that case, you will need to grab something from a beauty supply called porosity control, or Porofill. This gives semi-perm dye something to 'stick to' and will improve your results if your hair is too damaged to take in color well.
