The products for men that advertise they color in short time periods are growing on the market in favor of those that develop in 35 or 40 minutes. Research shows that most men will not color if they have to wait a long time. Haircolor technology has advanced to a point that products are continually being developed that take less time and they do a really good job. One of the the manufacturers of these products is sending me information about their products that I will post on my Hairnews column when I receive it.
