I was looking for something to make my mornings easier, and this brush has done the trick. It's not as heavy as others of its kind, so my arm doesn't get tired during the process. Key points: Temperature settings: It has several settings; I use the medium setting to avoid damaging my hair. Ionic technology: It really does a great job of controlling static and frizz. Design: The handle is ergonomic and easy to use. Note: I recommend drying your hair about 80% with a regular hairdryer and using this brush for the final styling; this way, the result is flawless and it takes much less time. Read more

I've fought frizzy hair for as long as I can remember. I've used the Instyler to smooth my hair for years, and it's worked pretty well. However, I think I've recently damaged a section of my hair, compliments of too much heat from the Instyler. My hair is never smoother than when my hair stylist blows it out, but I'm just not good at blow drying. I thought I'd try a blower brush, and did a lot of research. I didn't want to spend a fortune, I just wanted to try something different, easy, and that would put less heat on my hair. Several of the reviews I read for Conair's Dr. Knot were what sealed the deal for me purchasing this. I was surprised how much faster my hair dries, and even though my hair is just about chin length, the brush attachment does an amazing job at smoothing. It seems to be plenty of power without putting too much heat out. I love that it also has settings. I've not mastered the comb lift attachment, but that's not something I really need for my style, which is pretty much your basic smooth bob. The price for something so effective is phenomenal. You don't need to spend over a hundred dollars to get an effective, quality, easy to use brush dryer/styler. Take it from someone who has always struggled with hair that reacts badly to humidity, this gizmo is a gem! Read more

I like that it doesn't fry my hair. It does a great job giving me a nice, quick blow out. You do need protective heat spray and you do need to let your hair air dry a bit (it isn't for just out of the shower wet hair). Con: the first one I ordered, the cool shot button didn't work. The replacement one has a working cool shot button, but it isn't truly cold air that blows out as with Conair's traditional hair dryers. The air is warm, just not as warm as the lowest heat setting. I have two different traditional Conair hairdryers and both models' cool shot buttons produce cold air with helps set the hair style. I took off a star for the Knot Doctor's cool shot button for not working as well as Conair's other hair dryers. Read more

I had been using a different brant of brush-blow dryer combination and loved the results, but always was coming close to burning my fingers when trying to manipulate the brush too close to the heat source. And I worried that it might be causing damage to my hair -- a thought that was confirmed by my hairdresser. So, when I was reading reviews on this brand and saw a few mentions about the temperature options, I decided to try it. Best ... decision ... EVER. This brush styles my hair in the same manner, in the same amount of time, but with far less damaging heat. On the "medium" setting, which is what I use, I can easily manipulate the brush to help me catch sections of hair near the base of my neck (you'll see from the photos that I wear a shorter style). I actually feel like this product, when used on "medium," emits far less heat than most blow dryers. (It does have a "high" setting which is hotter, but not nearly as finger-burning-hot as my other blow dryer/brush combo.) I liked the root-lift tool (although I don't use it all the time, and I also purchased the diffuser, because my husband has curly hair and I do a "beach wave" with mine once in a while. TIPS: Use a blow dryer to partially dry your hair before styling with this (especially for people with lots of hair, like me). It will significantly decrease your styling time. Also, I do my hair in sections, pinning up the top as I do the bottom layer, then moving up layer by layer. By the time I am nearly done, there is a "rectangle" of hair surrounding my part -- from the back to the front -- that is remaining. I section that into three or four pieces, starting at the back and finishing at the front. Love this dryer brush so much that I sent one to my "sister from another mister" to try! Read more

Love this product. I’ve always had frizzy hair after blow drying then would have to use a flat iron over it to control it. I wash my hair at night, dampen it in the morning then use the Infinitipro to dry and style. I have medium length hair and it’s so quick and easy to dry and style. Great value and quality for the price. Read more

This product is okay. I have thick course hair and usually need high heat for a flat iron, curling iron, hot brush to get my hair to be sleek. I used the first revlon for 2 years on my hair. And while some complained that it was too hot. It did the job great on my hair and shortened the time for me to get the job done. It died a month ago so I looked up reviews and saw great things about the knot Dr. I am debating on whether I will return this tool. The tool is light and easy to hold. It blows a lot of air but it is warm air not hot like a blow dryer. It still dried my hair and made it semi straight but I will have to go back over it with a flat iron. It took longer to get it to the dry point since the air isn’t that hot. My hair still looks a little puffy if I decide not to go over it with a flat iron which I suppose is a look I could sport. I think this will likely get returned. I wouldn’t recommend for people with thick course hair. But I think it would be great for people with thinner hair. Read more
