ELI5: why is scalp skin so different from other skin?
gpt
The skin structure of scalp is basically the same as other parts of the body. However, since it has more lipid glands and sweat glands compared with other parts of the body, it becomes dirty very easily from sweat and sebum. Scalp has a lower barrier function and therefore it has a lower ability to maintain and replenish moisture compared to skin on other parts of the body. Therefore, it is more likely for skin problems to occur on the scalp than on other areas of skin.
