There`ve been a lot of threads/posts regarding all kinds of products and their merits/de-merits.
I guess again, it a question of common-sense really...if you`re using a product that you know may have a negative effect, try to counter-balance by using positively beneficial ones as part of your care/maintenance routine. I can recommend the `Remysoft`3-stage range and use a good leave-in conditioner ... dryness is the main enemy of system hair so anything which moisturises the hair will prolong the life of your system.... I also mist mine nightly with water and allow to dry naturally ....... Paul.
