Let's take a look at shampoo for patients with scalp or hair-related diseases. Shampoo is used for cleaning hair. Shampoo contains a variety of ingredients, and surfactants enhance shampoo's cleaning power. Surfactants are substances activated at the interface where substances of different properties, such as water and oil, meet, and they are molecules that can function at the interface where they do not mix together, such as water and oil. Surfactants are used in shampoos for their excellent cleaning power, dispersing power, emulsification power, and sterilization power, so they are also used in industrial and household use, as well as in industrial and household use, to clean the scalp and hair.

However, if a surfactant is added in excess, it can irritate the scalp and hair. In particular, sulfate surfactants are highly irritating, so stimulating the scalp can increase the risk of hair weakness and hair loss folliculitis. In addition, surfactants can cause inflammation and itching of the eyes due to skin irritation, and frequent exposure can cause dandruff, dryness, itchiness, smell, rash, acne, scalp inflammation, and hair loss.

Therefore, patients with scalp or hair-related diseases have sensitive skin, so it is important to properly check the content of surfactants when choosing shampoo. In addition, using shampoo with natural surfactants is less irritating to the scalp and hair and is healthy.

Jung Ji-yoon, head of the Korea Women's Health Institute, says that for people with symptoms such as scalp disease and itching, checking the use of surfactants will help them manage their scalp.
