Q: Is it possible that two brands of high-end hair dyes will result in the exact same shade? Or close enough? My hair
stylist proposed switching me from semi-permanent hair dye of one brand to permanent dye of another brand because I'm becoming dye
resistant. I want my color to remain the same. Will my hair stylist achieve the same color if she crosses brands and the original
color is a semi-permanent brand and the new one is a permanent hair dye?
A: You should understand that the majority of the results you get from the color products used depend largely on the skill of the
stylist using the products. A good stylist can blend colors and create matches to hair color shades as desired, and to prevent
unfortunate color results.
As for the colors available from different brands of professional hair color formulas, there
are usually many “duplicate” shades among the various brand names. Since the color of hair is graded by lightness level and base
color you find that there are a finite number of colors available. It is only reasonable to assume that there will be some crossover
of color. The only real differences are often the names used. Where one maker has colors like “Light Auburn”, and “Intense Red”,
another maker will use names like “Red Oak” and “Flame” or “Coppertone” to indicate nearly identical shades.
The real question comes to a matter of trust in your hair stylist. If you have been happy with the
service received in the past, then you should feel pretty confident that the stylist will not steer you wrong. The only thing I will
say is to remind you that your permanent color applications will not respond the way your semi-permanent colors have done. You will
not get the gradual fading of the color as you shampoo, but will instead see clearly defined lines of demarcation as the hair grows out.
