Many people believe that using a hair dryer leads to hair damage, but in fact, air drying can be more harmful to your hair. When you leave your hair wet without drying it, the cuticles remain open, which causes moisture to escape from inside the hair, leading to dry hair. Drying your hair with moderate heat from a hair dryer helps close the cuticles, and smoothes the hair’s surface,  resulting in soft, silky hair. Therefore, whenever possible it's better to use a hair dryer after shampooing 

Nowadays, there are a wide variety of hair dryers, including powerful ones and models with ion generators. For those with thick or frizzy hair, using an ion hair dryer can help control static and make the hair more manageable. I also highly recommend using leave-in treatments like Doux Luna (for fine to medium hair) or Doux Stella (for coarse, dry hair) before drying. The combination of the treatments and heat from the dryer will enhance smoothness and manageability.

Lastly, when using a hair dryer, direct the airflow from the roots to the ends for the best results!
