Hi
I don't know if you are familiar with Affinage Eraser - it doesn't contain bleach at all! Unlike other colour removal systems, the low pH level of Affinage Eraser conditions the hair, leaving it in better condition than when you started!
I have used this product ever since it was launched, and have recently moved onto Blondie Rae which is very similar (but cheaper :biggrin
Colour removers of recent years have been rubbish and contained nasty chemicals, including formaldehyde, ammonia, bleach etc which is probably why you assumed that all colour removers are 'a form of bleach' Maybe try using them and see for yourself how the clients hair feels, because I have never encountered any damage from using these colour removing products.
As for conditioning treatments, they can be very beneficial to dry, damaged and over processed hair. Bleaching raises the hair cuticle, thus making it porous - A deep hair conditioning treatment doesn't just act on the surface and coat the hair as a normal conditioner does; instead it penetrates deeply into the hair shaft itself in order to help restore moisture lost by over processing. I would recommend the redken all soft range, or bumble&bumble quenching masque, :hug:
