since you are not willing to change the main brand, you can continue the same but change the interrnal brand,,replesnishing shampoo and conditioner(both seperate bottles and not 2-in-1),,its ok to use for permed or coloured hair,and it comes for all types of hair. i just washed my hair and knew the whole name of the shampoo i was using,,its clairol herbal essence Replenishing Shampoo and the conditioner as well..i use the one with jojoba,vit e,rosehips...conditioner often comes along with it...
and i think it wont be much a problem for you if you change the internal series,,,often the base of the shampoo remains the same in the internal series,,only the some addins or other agents are added !!!! so this wont make you feel ne change in your hair.
also if you are having scant greys around your roots only, then using root touchups color series ! its the same clairol brand !!!
hope this helps..jst my opinion !
