I can`t comment on Debbie`s maintenance products , but as you can see ,she does sell them....why not just order the lot from her for your first order ? The problem with shampoos you buy in shops is that many contain sulfates [spelled `Sulphates` in this part of the world !! ] which are not kind to system hair..... I used the Remysoft for a few reasons..I must say I`m really pleased with them, and they DO leave the hair in a lovely condition.... you`ll have to decide on frequency of washing etc. depending on your own individual needs/how it looks over time etc. I find using too many things like Gels etc leads to build-up and hair looking lifeless....then you have to shampoo.... nothing wrong with shampoo as such, but personally I like to use leave-in conditioners more frequently than shampoo...that`s just me though !
