Final answer:
Control hair while blowdrying to prevent frizz, which is caused by lifted cuticles from incorrect drying technique. Using a heat protectant and proper brushing can minimize frizz.
Step-by-step explanation:
When blowdrying hair, it is important to control the hair to prevent frizz. Frizz is a common problem that occurs when hair is exposed to heat and airflow without proper control and technique, leading to a rough, fluffy texture due to the cuticle layers on the hair strands being lifted. To minimize frizz, make sure to use a heat protectant, keep the dryer at a distance from your hair, and move it continuously. Using the right brush and directing the airflow downwards from the roots to the ends can also help to smooth the hair cuticle and promote a sleeker appearance.
