I forgot to say in the last post --you asked about cutting your own hair --- normally the stylist who you use to do your cut -in would be happy to cut your own hair when needed, though I often trim my own with the unit off my head but my hair is quite straight and fine so it`s easy to take the electric shears to it but it`s best to get a good stylist ---especially the one who is aware you are wearing, as they will avoid any disasters !
Did you track down a salon /stylist yet ? I found here that the ones which actually supply hairpieces [at huge prices] are not inclined to oblige you with a cut -in unless you have bought from them so it`s likely you`ll find the same attitudes -- interested to know how you get on with that particular aspect of things.
