Cold weather and the thought of being cold washing one’s hair at home drives many people to the salons to have their hair washed. Besides being wary of other people using excessive force when washing your hair, the detergency of the shampoo might also be too strong, possibly causing hair-related allergies or even hair loss.
When going to the salon to have your hair washed, many people ask salon assistants to scratch their scalp harder while washing their hair. The assistants also generously apply thick layers of shampoo directly to the scalp and then add water and scratch until foam appears. Dermatologists warn that such actions are not good for the scalp.
Dermatologist Chao Chao-ming says that he recently had a 28-year-old pink-collar worker patient who on average was going to salons once every three days to have her hair washed. After a period, her scalp became dry and itchy and she started suffering hair loss. She had no other option but to see a dermatologist. The doctor recommended that she only wash her hair at home and her condition eventually improved.
Chao says that using excessive force while washing your hair can damage the scalp and cause inflammation. Putting a plethora of shampoo directly on the scalp is not ideal either, particularly if the shampoo is substandard, which means that it probably contains a lot of petrochemical surfactants, synthetic fragrances and preservatives that can irritate the skin and cause allergic reactions, Chao says.
Regarding how to go about selecting the right hair products, Chao says that when choosing a shampoo, one should avoid products that excessively stimulate the scalp, and be sure to look at the label showing the ingredients to avoid products with too many chemicals, surfactants, fragrances or preservatives.
