Using A Cheap Blow-Dryer
The good ones have smart settings to give you the desired look with lesser damage.
Brushing Too Early
Don’t start brushing your dripping wet hair. Let them rough dry and use a wide-toothed comb to brush them out.
No Heat Protectant
It’s very necessary to use a heat protectant each time you use a blow dryer or any hot tools.
Not Using The Nozzle Attachments
Those attachments ensure that the heat is applied to specific areas (please section your hair when you blow-dry) from a safe distance for lesser heat damage.
