I got this hair dryer at the end of February, and have been using it pretty regularly since then. (3-4 times a week, for me.) I wanted to make sure I gave it some time and a fair amount of use before I reviewed it, so I'd have a better feel for it.
The first thing I want to talk about is the keratin aspect. This dryer has a ring inside the nozzle that (claims to be) infused with keratin. They say this will last the lifetime of the dryer (and just how long is that supposed to be? Anyone?) and it is supposed to be "activated" when you turn the dryer on. They claim that this will help give you sleek, strong hair and help protect your hair during styling. Not too sure how I feel about all those claims, honestly. I was never good with science so maybe I'm just dense but I don't see how it would work. But, I need to note right now that this particular feature was NOT a key selling point for me.
At this time, I can't say I have noticed a difference in my hair as far as any possible benefits of this keratin infused ring in the dryer. But I also need to tell you that I currently don't have any mirrors other than the couple that are in a couple of my cosmetics products. So, I haven't exactly been able to really give my hair a good look to determine any possible difference in it now as compared to before I started using this dryer. Being in the midst of major home remodeling, we don't even have all our walls and ceilings replaces yet let alone have a mirror up in the bathroom. The bathroom is one of the rooms still lacking in walls and ceiling, so there is nowhere to hang a mirror. Yes, my hair is long enough I can see the ends effortlessly over my shoulders, but that's not quite giving the full effect you'd get looking into a (big) mirror to get the full picture. If I'm going strictly by how my hair feels and not considering how it looks; I honestly can't say it feels any softer/smoother than before. It's also possible it takes more extended use than a couple of months to notice any benefits from it, as often things like this do take time to become noticeable. I'm not holding my breath on that one though. As of right now, any difference it may be making is slight enough that I haven't really been able to tell.
But again, this was not really a feature that was going to make or break this dryer for me personally; I chose this model for other reasons. If you are looking at this dryer specifically for the keratin aspect though, I'm going to have to say I don't think it really makes much of a difference.
Now. On to the things that did make me choose this dryer! Besides the gorgeous, soft golden champagne color (seriously, how beautiful is the color?!) I chose this model because I like the general style. Yeah yeah, it's a hair dryer, they tend to be a lot of the same and few differences. But I like the overall look; it looks sleek and fancy. To me anyway. It is lightweight. I've got the upper body strength of cooked spaghetti so if I can handle this dryer with no problems I am sure anybody can! It fits comfortably in my hands, and the controls are spaced & placed well so I don't have any issues with them.
It has a sturdy hanging loop at the base, which comes in handy. Well... if you have a place to hang it. Which I don't. But when I do, that's a key feature in a dryer for me!
The back filter is hinged so it's easy to pop open and clean.
The dryer has two speed settings, three heat settings, and a cool shot button. The cool shot button is not a toggle style button like the speed and heat settings, you press and hold it when you want to use the cool shot. I'd actually prefer a toggle style, or something that you can press and release but maintain the cool shot then press again to resume using heat. But I can work with it as is.
The dryer comes with a concentrator attachment, which I forgot to take pictures of. It's easy to use and just pops on and off of the nozzle. One bad thing I need to mention here is that on the Remington site they say that you can get a free diffuser attachment as well by redeeming a coupon code that comes included in the box. When I attempted to redeem the coupon, it did reduce the price of the diffuser, but did not make it free. I contacted Remington via the contact form on their web site about this and asked if the offer was still valid, and if it is not then they should update their web site to reflect this. I don't absolutely need the diffuser but would like to have it. Granted it's a cheap attachment to buy separately, however I was under the impression that I'd be able to get it for free. I wrote to them about this on February 26th. To date, I have not received a response to my query. I've not felt it is an important enough matter to write to them again about it, but I do have to say I'm a bit disappointed by this. I've used numerous Remington products over the years and have always been very happy with them. I expected more of their customer service.
And now the biggest thing (sorry, I know I took a while to get to this point but I wanted to cover all the bases!) - how well does it do the intended job of drying hair? I have one word for you:
I've had dryers in the past that despite the 1875 watts (which is what this dryer has) still took close to an hour to dry my hair and even then it was often still pretty damp and I only stopped drying because my arms were tired and I was fed up with the process. Not fun to have to stand around that long drying your hair! This dryer, however, does the job in 10-15 minutes! Note this is starting with towel dried hair, not dripping wet hair. I start with the dryer on high speed and high heat for several minutes to get my hair dry enough it's still just slightly damp, then reduce the heat to medium for a couple minutes. Once it's almost totally dry I switch to low speed for a bit, then also reduce the heat to low. I finish it off with a minute or two with the cool shot. Depending on how wet my hair was when I started, I'm done with this whole process in 10-15 minutes and have totally dry hair! While it's powerful enough to to the job in a speedy manner, it does not blow my hair around like crazy causing tangles like some dryers can. I can't really say anything about how loud/quiet it is. It's very quiet on low speed, and of course louder on high speed. Pretty average there, I think, but that's as can be expected. I mean, it's basically a compact, high powered heater/fan - it's going to be loud. That's what makes it able to do it's job in a timely manner. So I have no complaints there. Reminder: my hair is thick, coarse, and currently just a couple inches shy of hip length. If you have significantly shorter (or longer) hair you may need more or less time to dry your hair. Note that this is also the time just to dry my hair, not to do any kind of styling while drying.
Overall, I'm very pleased with it. It does what I need it to do, and it does it well. I would definitely recommend it if you need a good, affordable drier. I don't recommend you go into it with any expectations of the keratin bit - but if you just like the general style and want a good hair dryer, this is a great option. Don't count on that "free" diffuser if you need it - you'll have to pay at least a little for it. Unless maybe you can wrangle a response out of Remington about it.
