Pop quiz: What’s the healthiest way to dry your hair? If you said, ” air-drying, clearly,” you would certainly be misinterpreted. With the ideal method, making use of a blow-dryer is in fact better for your hair’s health and wellness than allowing it air-dry, according to a recent study from Korea. Just how can that be? First, a little hair anatomy: Each hair of your hair is essentially a tube with an internal cortex as well as a protective outer layer (called a follicle) held with each other by delicate proteins. “When the cuticle layer is flawlessly undamaged, then hair is really shiny as well as doesn’t have a tendency to break,” claims Jeff Donovan, MD, a board-certified dermatologist as well as hair restoration physician with Hair Club Medical Team in Toronto. Way too much warmth can damage the follicle by trapping water inside the cortex as well as really triggering the water to boil (yikes). Seems like a case for air-drying, but obtain this: The research study discovered that while the heat of a dryer can trigger extra damages than not making use of one, utilizing a hair-dryer at the best range and also temperature level can really trigger less damages than allowing hair air-dry. That’s because when hair is available in contact with water, it swells. The longer the swelling goes on (claim, for the 2 hrs it took for hair to air-dry in the research), the more pressure it puts on the fragile proteins maintaining hair undamaged, which can cause more damages. Right here’s the just-right formula for drying your hair the healthiest way possible: First, let your hair completely dry naturally, concerning 70-80% of the method dry. Then, with your clothes dryer on the coolest setting (do not touch that warm setting!), blow your hair completely dry, keeping the dryer regarding 6-inches far from hair in any way times and also relocate around continually. Voilà: gorgeous, healthy hair, without the heat. Much more from Prevention:.
