Q: How long do hair dyes last? How fast does hair color fade and how often will I need touch ups?
A: The duration of the color depends on the type of haircolor. Temporary color only lasts until the next shampoo. Semi-permanent and demi-permanent colors last 8-12 shampoos. Permanent haircolor, however, is just
that: permanent. It lasts indefinitely. Depending on the color chosen, there may be some fading, but the primary concern is going to be new growth and the need to color the naturally pigmented hair once it has
grown out enough to become visible and problematic.
Some color choices (specifically some reds) may fade more readily than others, but in general, the colors wonít need refreshing before the point at which you need to
address the new growth issue. Because of this, you can simply do your retouch service at the usual time (5-8 weeks) and then bring the color through the hair at the end of the processing for the retouch in order to refresh the color.
The variance in the length of time between retouches is largely dependent on the rate at which your hair grows. The average rate of growth for the hair is one-half inch per
month, but some people may have slightly faster or slower rates of growth. Feel free to simply gauge when itís time for a retouch service by when you see new growth in your style. This will ensure that your
hair looks good on your timetable.
