Oh I am sure the ladies at Sally's recommend it, just like they highly recommend the Jilbere flat iron which is like lighting a match to your hair. At the begining everybodey loves them, and two weeks later they are crying about how fried their hair is. Trust me, I manage a retail store for one of the largest companies in the country. Sales people don't always now what they are talking about. Next time you are in the store, ask them why the product is so good. See if they can come up with a logical as well as technical answer. If they now what they are talking about they will explain to you the product formulation, what the different ingredients are and why they are good for your hair. For example did you know Cholesterol is full of carcinogens, and that the waxes in it are not low melting waxes, so they clog hair follicles and cause brakage. Ask them if they now what the different chemicals are supposed to do.
I walked into a beauty supply not too long ago, I usually just play along and let them think I don't know anything, and that I believe everything they are saying just so they will live me alone. This lady has worked for many of the major beauty companies; Loreal, Sebastian you name it. She has been doing this for like 15 years. Still her knowledge comes from the training that the sales reps provide. She really did not have much chemistry knowlege. Or any idea about what the different ingredients are. For example if you ask them what is alcohol Denat and what is it for, they have no idea. So you see, most of their knowledge comes from hear say. "Oh alot of customers buy it, and they love it". Well I'll tell you what I Manage a store for the largest retailer of pet supplies in the USA. A ton of my customers buy Eukanuba dog food and swear by it. Mind you this food is almost $40 a bag, and it is advertised by the manufacturer as a super premium food. I walk by the aisles and listen to other customer rave about what a wonderfull food this is, and how it is the number one. And based on the price it should be. However if you know anything about ingredients and at least a little about chemistry, when you turn the bag around you will realize that you can get a much better food for about $15 less. Now these are my vendors and I won't display here what is wrong with the food. But lets just say that just because alot of people recommend something doesn't mean they really know about the product. I make sure that at least at my store, my associates know what they are talking about when selling to a customer. I role play with them, and when they recommend a food to me as they would to one of my customers I make them tell me why. If they don't know, then I'll personally train them, so they won't missinform my customers.
I'll even give you a better example. The number one selling food for dogs is Pedigree. You will be surprise how many customers drop their jaw when I tell them that the food is a low quality brand, or what is know in the pet business as a grocery brand. They thought that Pedigree was suppossed to be the best food, because they watch so many comercials about it, and because that is what all their neighbors feed their dogs, and they swear by it. Well when they approach me, is usually because the dog is having skin problems and severe shedding not to mention a very dry and dull coat. The first thing I ask them is what kind of food do you feed him. The answers is 99% of the time "Pedigree", and the other one % is another grocery brand "puppy chow" or kibbles and bits. So I tell them, I could sell you that shampoo but that won't solve your problem. You either switch his food or buy a skin and coat supplement, which you will have to keep buying as long as you use that food. So you see, it takes alot more knowledge than you think to recomend a product. Luckily I was a Biology major in college and had to take plenty of chemistry, I don't know as much as ekatherine (I believe she is a chemistry major) but I know just enough to shut down sales people when they are trying to B.S me. If there is one thing other than pet supplies that I know about is hair products. Believe many of them seem to work but are not neccesarily the best. Your hair is your most important accesory, don't take chances with it, use only the best. And do your own reseach about the ingredients themselves, don't just go by sales people tell you. After all, they are there to sell. Remember You can grab 10 people and give them the same ingredients to make a cake, and each one of them will come up with a different cake. Is also alot more than just mixing ingredients. There is a certain technology to it as well.
I don't mean to lecture you, I just like for people to know the facts.
Hope it helps. Wish you good luck and great hair.
