Is Blow-Drying Bad for Hair?

Is blow-drying bad for hair

A blow dryer is a tool that works through electricity to generate heat that helps to dry out and style hair. When hair is exposed persistently to intense heat, it is undoubtedly going to cause damage to the hair (1).

However, blow drying is not completely bad for hair unless you do it correctly and use enough hair protection against heat. Along with these, there are many more precautionary measures that we will discuss in this article that one should consider while using hair dryers to avoid hair damage.

Our hair strand is made up of three layers: cuticle, cortex, and medulla. Cuticles act as the outermost layer that protects the inner layers. So, when the heat from blow drying causes damage, it is usually the cuticle that gets affected.

The hair cuticle can also tolerate damage within a limit, after which it is impossible to reverse the effect that caused split ends and frizz in the hair.

So, the simple answer to, does blow drying your hair damage it is YES.

In fact, any type of heat-styling tool is terrible for hair (2). The hot air, when blown into wet hair, incapacitates the cuticles, making them susceptible to breakage, dryness, and tangles.

Precautions to Take While Blow Drying

Even though the heat from a blow dryer or any other heat styling tool can damage your beautiful locks, there are ways to prevent it. Using few precautions, you can protect your hair from harm that a blow dryer can cause.

  • Use a heat protectant: Whether you use a blow dryer every day or occasionally, you must start using a good heat protectant spray or serum before you start blow-drying your hair. The heat protectant creates a thermal barrier over the shafts, that is, it coats the hair strand, forming a thin layer around it to safeguard it against the heat directly. Additionally, it retains moisture and provides temporary structural support to the hair.
  • Heat setting of a blow dryer: While blow drying, we tend to use the highest setting for the hair to dry faster. Although it gets the work done faster, it hurts the hair the most. We should not blow dry, dripping wet hair instantly. Instead, it would be best if you initially dried it using a towel and then, after a while, used the dryer in a low to medium setting. The higher the heat, the more damage. So, try to keep the setting to the lowest for maximum safety of hair.
  • Use the nozzle and diffuser of the blow dryer: The nozzle and diffuser are attachments to your blow dryer that help attain a definite blow-drying effect. A wider attachment distributes more heat.
  • Maintain proper distance: You should always blow dry keeping the dryer at least 6 to 8 inches away from the hair and start from the back to the front of the head. While this distance is considered safe for hair, it also allows even distribution of heat instead of only one section which is more damaging.
