Color Resistant Gray Hair

Gray Magic
Q: I have been using L'Oréal hair color for a long time. I am now having trouble coloring my gray at the nape of my neck and the front by my ears. I use 8g hair color. I have gone slowly form 6 to 9G and thought if I went back to 8G it would grab on to the dye. Isn’t there something that I can use on the gray areas before I color that will help the dye grab?
Everything I have tried isn’t working. I don’t want to go back to darker hair because dark colors are to harsh looking for me and my skin tone. I would appreciate any help that you might have.

A: If your problem is what it sounds like, your gray hair is becoming resistant to the hair color you are using. This is a common problem since much gray hair has a tighter cuticle layer than pigmented hair and chemicals have a harder time penetrating into the hair shaft. The solution can be very simple if you have a beauty supply shop nearby.
Look for a product called “Gray Magic”. It comes in a small ampule and is designed to be added to hair color to help the color penetrate resistant, hard to color gray hair. It is generally found in the hair color aisle with the other hair color products and accessories. If Gray Magic isn’t available in your area, and the Beauty Supply doesn’t have a similar product available, you can use a technique called “presoftening”.
Presoftening involves using hydrogen peroxide developer on the resistant hair to open the cuticle layer prior to the application of hair color. Simply apply 10-volume peroxide developer to the resistant areas for approximately 10-15 minutes, then wipe the developer away with a clean dry towel and apply your hair color as usual. This should allow the hair to accept the color more readily and give you more pleasing results.
