Q:
When I dye my gray hair, the brunette color doesn't take all over. Help!
A:There
are a few things you can do to prevent your hair from suffering from Teflon
syndrome when it comes to color. First, be sure the product you're using is a
permanent and not a demi- or semi-permanent formula, says colorist Marie
Robinson of the Marie Robinson Salon in New York City. Most permanent color
contains ammonia and peroxide, which penetrate the hair shaft, staining it. (L'Oréal
recently introduced INOA, a salon-only permanent dye that contains no ammonia
but works the same way.) Choose a dye that's labeled "neutral" or
"natural"; these colors have the densest pigment and cover gray
better than dyes called "gold" or "ash." Also, rather than
use the squeeze bottle provided in the box to apply the dye, empty it into a
nonporous bowl and use a tinting brush with coarse bristles .The brush will
roughen the cuticle of the gray hairs, making it easier for the dye to
penetrate, says Robinson. Finally, leave the formula on for at least the
recommended time, if not a little longer.
Keep in mind:
You
might enlist a friend to check the top and back of your head so you don't miss
any gray.
