I have a high demand for image. I often use a curling iron. Can long-term use of curling iron cause harm to hair?

1. Never underestimate the damage caused by thermal modeling tools when modeling with curling irons or chemicals on the scalp. When the hair follicle is injured, the medicine can't recover, and because of its lag effect, it may take months or years to find that the hair has not grown well.

2. When the hair is wet, a hot styling tool will be used, and the water in the center of the hair will boil to produce bubbles, which will cause the pulp layer to crack, just like breaking the wall. The stratum corneum will also crack because of these bubbles, lose its luster, become rough and can no longer reflect light. Wet hair is like a loose spring, which is easy to stretch, but excessive stretching will lead to split and broken strands.
