#10-Why do you not advise to avoid ponytails, barrettes, ear tucks, etc...during the wait period?

Here's the deal. All manufacturers say not to style the hair in any way before the first wash, after the salon treatment process. However, over the years, clients would confess that they had, in fact, worn ponytails, clips, headbands, etc, and no mark was left. So, a contest was started which would reward a client with a free year of straightening, if they could leave a mark in their hair by any means, other than chemistry(sweat, rain, product...) Clients, in great effort to leave marks, did corn rows, micro braids, ponytails, bobby pins, headbands..... everything they could think of. Even after a year or so of all this craziness, not a single mark was ever left. Most of the mark-making-attempts were photographed and emailed to Global Keratin(The brand of SP-S we use) as proof that marks were basically impossible to leave in the hair.  When we asked Global Keratin, "why do you advise clients not to wear ponytails, tuck it behind the ear, etc...", they said that ultimately, we(the stylists) are the experts and could advise the clients however we saw fit. It's clear, however, that when a stylist recommends something contrary to what the manufacturer says, it's the stylist that will look uninformed, not the manufacturer. This point was brought up to them, to which they replied, "Your client should trust that you are doing what's right for them..."The rep at Global Keratin could not say why the brand ever decided on the "no-ponytail/bobby pin/etc" rule.

Humm.....   so basically, I've never seen a mark left, other than if someone got their hair wet, or put product in the hair during the wait period. I personally wear a head band, and ponytail the entire duration of the wait period. Most clients do as well.
