It’s a well known fact that prolonged exposure if the hair to heat can cause permanent damage the layers, leaving you with no other option than to go for a shorter haircut. So how can we use our blow dryer and preserve, at the same time, the health and shine of our hair? There are a few key rules experts dictate that can help us do precisely this, and they’re presented below.
The first secret of keeping your hair out of the heat’s damaging way is to do just that. While your blow dryer can reach great heat levels, always keep it at medium. Higher temperatures will work on coarse, thick hair, but for most of us, overheating is extremely damaging. If you have the possibility to use a cool shot, make it happen, as cold air is a great cuticle sealant and will help stop the dehydration process.
Blow drying requires previous washing. It’s important that you use a conditioner – better a leave-in one, to keep your hair as moisturized as possible during drying. Also, if possible, apply a heat protection spray or serum – preferably silicone-based.
Keeping the dryer at a good distance is also crucial in protecting the hair. Somewhere between 6 and 10 inches is more that enough for your hair to receive a full air blow, and to avoid getting overheated.
And since you’ve just walked out of the shower, take a few minutes to pat your hair with a towel, and give it some time to air dry at least until it’s just damp instead of wet. Applying heat on a dripping wet hair will only warm the water, making the high temperature reach deeper into the hair.
We’ve been talking about what “too hot” does, but “too long” is also a problem. You might get the impression that keeping the dryer focused on a single portion at a time will get your hair dry faster. But while you’re drying that portion, you’re also keeping the hair from cooling, and overheating leads to severe dehydration.
