Product review (5 stars): LOVE MY HAIR NOW!
Oh. My. Gosh. Wow. Background first:  I have medium (near shoulder length) super fine AND super thin hair,  with a giant C-shaped brain surgery scar over the entire left side of my head, where the hair doesn't even grow. I have layers, short on top and in the back. My main issues are thinness and scalp showing on the left side and top back of my head. Most of what I do is useless to fix that. And the front, my bangs area,  is also thin and shows scalp. The rest of my hair is good enough, but looks kind of out sync, I guess you could say: Full and frizzy on the bottom area,  thin and see-through on the scalp area. I've tried most everything that I can afford.  Chemicals, chemical-free, different cuts, styles, colors, my own natural color, sprays, gels, mousses again naturals, earthy types,  and chemical ones. Shampoos, conditioners, even just rinsing. Daily washing to every few days.  Blow drying, air drying, boar bristles...  You get the idea. Before my surgery, I used to use a round blow dryer that was stationery. It worked OK,  but would die or get super hot all the time after not too much use and I got tired of buying them. Decided to look into those again, and saw this one. Read the reviews and decided to try it.  Took me all of 3 tries (3 sections of hair on my first use, that is) to get the hang of it. It's so simple to use, and I have NEVER  seen my hair so smooth, shiny and silky! Truly amazed that a hair dryer can make it not frizzy.  Seems backward to me. All of my other dryers in my entire life have frizzed on me-- even ones that say they won't. The thinnest parts of my hair, though the hair does not poof up or anything, gets full scalp coverage somehow. And it lasts. My hair does fall flat in humidity, or if it gets damp from sweat, but the coverage of my scalp is still there, by some miracle. And I love that I can make it straight, or curly.  I almost want to buy 5 more just in case something happens to the company and  I can't buy any more. Part of this review is selfish for that reason... I want the company to succeed so I can buy more if I ever need to. I do wonder how long it will last because it has moving parts and a heater. But,  It seems really well made.  I'm even using the bristle cover every time I use it. Seems like the company really cares about the product. I love it, and have recommended it to my two friends with very fine hair and shoulder issues who can't hold a dryer AND a brush (yet another reason to buy this product). Love this product. Love it.
