I have taken a long time to assess this hair dryer before writing a review. I know it is expensive, much more than I am used to paying for a hair dryer, and I really wanted to determine if it was worth the money before I left a review, so others could have some feedback before they decided whether or not to make this purchase. Just so you know why I felt it might be worth the cost: I have fine, dry, color-treated hair, and it has been thinning for a while now despite my doing everything I can to protect it. I only wash it a couple times a week, using non-sulfate products, so it won’t dry,out too much, take biotin, etc. One thing I can’t really do is “just let it dry naturally”, which seems to be the answer so many people give me. My hair is just too flyaway and frizzy if I don’t blow dry it and style it into submission or put it back in a pony tail, which can also cause breakage. I have gone,to some really great hairstylists and they have given me good advice that helps. So I make sure that I use heat protectant products and splurged on this hair dryer to see if it might help. Overall, I really like the hairdryer. It is NOT lightweight, but I did not expect it to be. It came with all the accessories I wanted —diffuser, regular concentrated drying end (which I literally never use), the end that you can snap on and then click into place for the oscillating fan. I have to say, I LOVE the last feature and I use it practically every day. I feel that when I use this, my hair just looks better. I find the same styling I usually do results in a softer, slightly wavier look when using the oscillating feature, which seems more natural than contrived, and I like that. My hair has less frizz and flyaway than with my Babyliss dryer. The diffuser works just like every other diffuser I have used, except it is definitely better than anything Babyliss has.. Theirs do not attach well, fly off the end of the dryer one do not allow for enough heat flow between the prongs of the diffuser the way this one does. As far as the conditioning technology this dryer is supposed to have—I was really skeptical about that when I bought it, and I still am. Drawing moisture from the air to DRY your hair seems counter-Intuitive. Instead of conditioning the hair, it would likely just mean you would have to spend more time to dry it at all. So I would not put too much stock into that particular claim. I do think I would consider the infrared tech for my next hair dryer, though, as stylists I know swear by it. So, is this hair dryer worth the cost? For me, for the oscillating feature alone, yes, I feel it is. if any other dryer had that feature for less, I would definitely buy it, but since they don’t, I am satisfied with this purchase.
