I color my own hair, at home, using professional products. I've experienced no problems... that said, I wish I never started. yes I like the look of freshly colored hair for many reasons (it's softer, more manageable, shinier etc) but the routine is a drag. I am 59 1/2 years old. I will stop coloring hair when I hit 60. It may be a shock to see what color my hair really is. I am afraid!
