My old hair dryer burned out, and I'm thinking about whether to get the most powerful one. I've seen a 2500W one that seems to dry quickly, but does it overheat the hair?

A 2500W dryer is super powerful and dries your hair fast, but if you use it at full power all the time, it might not be the best for your hair. When I was thinking about getting a new one, I looked into this mini travel dryer. They're smaller but surprisingly strong, with some going up to 105,000 RPM. You get a lot of power in a tiny package without totally roasting your hair.

It's really interesting that a small hair dryer can be so powerful. Maybe it's better to get something compact.
