More Ways to Prevent Heat Damage

After using the right protective products before and after styling, here are some additional ways to help beat heat damage.

Partially Air-Dry Hair Before Blow-Drying

Allow hair to air-dry at least halfway before turning on the dryer. This cuts down on the amount of time hair is exposed to heat, lessening the chances of damage. Or use a product that helps speed up drying time on damp hair like best-selling Paul Mitchell® Super Skinny® Serum.

Choose the Right Setting

As a general rule, the finer the hair, the lower the heat setting should be on the heat styling tool. Discover the ideal temperature setting for your hair type.

Temperature Setting Hair Type
250-290°F (121-143°C) Fragile, Very Fine
290-330°F (143-166°C) Fine
330-370°F (166-188°C) Medium
370-410°F (188-210°C) Coarse
410°F-450°F (210°C-232°C) Very Coarse (Recommend For Professional Use Only)

Use the Attachments on Your Hair Dryer

The concentrator nozzle attachment allows for directional airflow giving you more control of heat when blow-drying while the diffuser attachment does exactly what its name suggests, it diffuses airflow for more fragile hair types.
