I recommend the Vidal Sassoon hair dryer for its excellent performance, even among budget options. The model number is VSD5129K in rose gold, and even though it costs only 20,000 won, it offers truly great value for money. You can adjust both the temperature and power levels in three stages. The airflow is strong, so my hair seems to dry really quickly. I don't use any other hair products, but I believe drying my hair quickly is a good habit for it.
