While what she told you could have some truth to it, I would definitely agree with what NetG and LibbyLiz suggested. Also, I'm not saying this is why she was telling you this, but it could be that they tell people that to get them to buy more products?
Btw, don't mean to hijack, but has anyone ever noticed how many of the people who work in places like Sally's or other beauty supply chain stores often have less than 'desirable' looking hair? I definitely don't mean that to sound mean or rude, because I'm sure there are plenty of people who think my hair looks like crap at times and wonder what in the world I use on it.
It's just a trend I've noticed. Unlike our own CurlMart owners, and Jessicurl for example. But then again, we pretty much know they are putting only good stuff in their hair.
