Hair Drying
Studies show that blow drying vs air drying hair is more complicated in determining which is better. Although blow drying may damage the hair, blow drying from a more appropriate distance of around 15cm and around 60°C temperature can be more healthy for your hair than pure air-drying.(Lee et al., 2011) (BORIES et al., 1984)
It is also possible to create an itchy scalp and other problems if one were to lay down with wet hair, such as sleeping.(Consumer Reports)
