Well it`s your choice on what you decide. I`ve had my fill when it comes to Salons. They have their own agenda...... you have read the forum here for the last few weeks , so it`s your choice if you want to order off here,to your own specifications, or go along with the Salon and her opinion on what you should or shouldn`t wear ---ANY system base will be visible to the eye in places, through the hair -- if Lace was so detectable, no -one would be wearing it and as you know, it is highly popular with wearers ---that fact in itself should tell you something. I don`t know why this particular Salon is [or seems to be ] ``Pushing`` poly. At the end of the day, you are the customer/potential wearer and it`s purely YOUR choice on what you want to wear. Paul.
