It’s easier to split your hair into sections. Think about how the hairdressers in the salon do it for you? First tie the upper layer of hair to the top of your head and dry the lower layer. Then release the wetness on the top of the head, and then blow dry in turn. You can also do this when you are at home, otherwise you will find that the hair on the surface is very dry, but the roots on the inside are still very damp.
Don't blow the tips of your hair first, the water seeping through the roots will make you useless. Dry the hair roots first, then blow the tips, or let the tips air dry naturally to minimize the damage of the hair dryer.
Keep the hair dryer 15cm away from the hair, avoid letting it touch the hair, too close will cause heat damage to the hair.
A common mistake that many people make is that the hair dryer is stationary when blowing on an area, so that the concentration of heat in one area can easily cause hair damage. Therefore, at the beginning, the hair dryer starts from the top of the head, with one hand pulling the hair away and the other hand moving the hair dryer.
The cuticles of wet hair are open. Blowing in the direction of hair growth will make the cuticles close. If you blow backwards, the cuticles will open, and the more you blow it, the more frizzy.
