I use Wella Color Touch as one of my Demi permanent lines and really like it. It does have a mild developer but does not damage the hair. Hair color does not work without some type of developer unless it is a stain, temporary rinse or the like. Since I do a lot of hair straightening, I use Redken Shades and Wella Color Touch as my demi-permanents and I feel that they do little to no damage to the hair. On the retouch I do the roots first under the dryer for 20 minutes and then comb through the ends the last 5 to 10 minutes at room temperature. Hope this helps.
