Blot your freshly washed hair with a towel, allow it to air dry for a little while, then start blow-drying only after gently straightening the strands with your fingers. It would be best if you turned on the hair dryer as soon as the hair is 70–75% dry. The reasoning is straightforward: the longer the strands are exposed to heated airflow, the more harm they do.

2. Drying With A Towel

Hair cannot be kept in embracing towels. By leaving a towel on your head for a long time, you merely simulate a sauna, which causes the glands to start secreting sebum actively. Since damp hair is so delicate, twisting it into a tourniquet can seriously harm the structure of the hair. But just a reminder: the hair dryer is weaker, so you are allowed to use a hair dryer instead of a heat gun. However, not vice versa!

High temperature is the most hazardous element for hair while using a hair dryer. Overheating causes your hairstyle to perish. The more “dead” hair there is, the worse the overall appearance of the haircut is and the more issues with it.

When using a hair dryer, the airflow force plays a crucial role in quickly drying hair. Consider that the hair dryer doesn’t remove moisture from the bulk of hair. Its temperature is insufficient for rapid evaporation. The hair dryer blows out the moisture in the air between the hairs. The speed of this operation will increase with the airflow.

Use specialized thermal cosmetics further to protect your hair from the hazards of high heat. Gels, mousses, and foams work since they are intended to be applied to damp hair before drying or styling.


Because a heat gun is a powerful device needed for building applications, you cannot substitute it for a hair dryer. However, you can use a hair dryer instead of a heat gun. Additionally, exercise caution while using the hair dryer since it might damage your hair if the temperature is too high.


How Hot Does A Hair Dryer Get?
