It's hardly necessary to add another 5 star review for this brush, but the brush is so fantastic that I wanted to add my voice to the chorus of others saying so. Assuming mine isn't the first review you've read, you've heard the brush is great, and I'm guessing that you, like me, are wondering if it's REALLY worth the price tag. I did too. And you might also be trying to find some tidbit of information to convince a reluctant spouse that buying a $200 hair brush isn't insane, which, let's be honest, it is, as my husband repeatedly told me. What convinced me really had nothing to do with the brush and everything to do with a general frustration buying crap. There are certain products that have risen to the top of their industry but that command a price premium - think Dyson vacuums, Vitamix blenders... the Mason Pearson is one of them. I have bought dozens of lousy hairbrushes in my life, most of them around $10. Sometime about a year ago, I splurged on a $40 brush that claimed to be "as good" as the Mason Pearson. It's not. It's essentially the same lousy brush with a hefty price tag. And when I think of all the money I've spent on brushes, it's considerably more than $200, and had I bought this first I would have saved money and aggravation and had a better product all along. I have no idea what part of "brush science" makes this brush different, but it feels AMAZING to brush your hair with it. So, here's what happened - I agonized over buying this. I read every review I could find. They all said essentially what I'm saying - it's the best brush, we're not sure why, but you should just trust me and buy it. So eventually, I did. The day it arrived my husband came over to watch me open it, naturally curious what in the world could possibly make a brush cost so much. And I think more than likely waiting with an "I told you so" chambered for when the brush inevitably was just a brush and nothing more. I ran it through my hair and immediately noticed a difference. It's is just so perfectly comfortable and it feels like the brush is actually massaging your scalp when you use it. I was standing in my kitchen, not in front of a mirror, but my husband remarked immediately at how silky and shiny my hair was - from ONE use. If I saw the scene play out in a commercial I would have said it was absurd, but it's true. One use, and my hair was so much softer and shinier that my husband noticed. I've been using for a couple of months now and I'm in love. Brushing my hair is something I look forward to. I have long, thick, wavy hair that I straighten, and it works great for me. I have a 7 year old with very long, thick straight hair and a 5 year old with medium length straight thin hair and it works well through all the different textures and lengths and they beg me to use it. The only thing I would say is that this is not the right brush to use on wet hair. I use a Wet Brush for that, which is no where near as nice as the Mason Pearson, but the instructions that came with it specifically said not to use it on wet hair and I believe them. I will be buying one of these for my daughters as they get older, because it will last their whole life and the earlier they get one the less they'll waste on cheap drugstore brushes. Every other brush I've ever used feels like running sticky fingers through your hair. Buy this one. You'll love it.
