I haven't had very good experiences with it. I think it's for the same reason that many of us have stopped going to stylists...too many of them think they know everything. They swear by the products they use, and some of them consider it an insult if you bring your own...like saying they don't know what they're doing. But it's really nothing personal...some folks just prefer a certain line. They *should* appreciate the fact that you're even trying to still go to them b/c some folks just go to a different stylist if they don't like what a certain stylist uses.
I've had stylists go on about how they only use products they're familiar with, etc which is completely justified but clearly if I'm bringing in the product, I can't be mad at the stylist for the performance (or lack there of) of the product. I mean, if you've been living with your hair all of your life, you should have a decent idea of how it behaves. Many stylists swear that they know every head like the back of their hand and they can prescribe exactly what your hair needs. This is NOT always true as witnessed by many ladies here.
On top of all of that, the minute something is wrong with your hair, they want to blame your products and suggest that you let them use theirs. There's nothing wrong with that; it just gets old and annoying to me.
I had a stylist tell me that if I was going to bring in my products, I would have to sign a release written by her attorney to protect her.
I understand her protecting herself but it's SO not that deep to me. I just stopped going to her.
I've also had a stylist say that her products are the best. She said, "We use what's right for your hair. Why are you always bringing stuff in here? Just because they sell it a the beauty supply store doesn't mean you need it. If you want to use all of this stuff, why don't you just do your own hair at home?"
And that's exactly what I've been doing ever since.
