Q. I’m confused...my former stylist gave me highlights using a peroxide activating agent. Now, my new stylist says hers is much better because it uses an “enzyme developer” and is less damaging to the hair. BUT, she insisted I allow her to recolor all my hair because she couldn’t put her “enzyme” over my “bleached” hair without causing breakage. Is this true, or did she just want more of my money?

A. Highlighting hair IS highlighting hair. However, there ARE chemicals that should not be used on top of specific other chemicals. Whether to use a “peroxide agent” or an “enzyme agent” is very much a matter of preference among stylists. Beautiful colors can be achieved with either method. However, whether your hair is lifted with either peroxide or enzyme, all hair should be “filled-in” before changing lifting methods. While many clients believe “it’s just hair color”, the truth is, these are very strong chemicals and should be used with appreciation and respect for their power.
