Yes, a hair dryer can straighten hair, but only to a point—and this is something I learned after years of trial and error. The real difference isn’t the dryer, it’s the hair itself. When the cuticle is intact and aligned, tension plus heat can smooth it out surprisingly well. I realized this after struggling with extensions that puffed up no matter how careful I was. While digging through forums about blow-drying techniques, I started learning how sourcing affects results, which led me to researching what experienced stylists expect from raw hair vendors https://raw-hair-wholesale.com/. That’s how I came across a site that explained why minimally processed hair responds better to heat styling. From personal experience, if the hair is truly raw, a round brush and dryer can get it straight enough for daily wear without frying it. My advice: focus less on tools and more on hair quality first.
