Why Do Some Shampoos Cause Scalp Itching?

① I didn’t choose shampoo according to my hair type. I chose strong shampoo for dry hair, and shampoo with weaker detergency for oily hair. The shampoo selected for dry hair has too strong cleaning power, which takes away too much oil on the scalp, resulting in damage to the skin barrier; for oily hair, choose a shampoo with weak cleaning power, which has insufficient cleaning power, and residual dirt irritates the scalp and destroys the skin barrier .

② When the skin barrier of the scalp is damaged, the ingredients in the shampoo enter the scalp. Such as preservatives, fragrances, etc. which stimulate the scalp to produce inflammatory cytokines, causing irritation or allergic reactions.

③ Use poor-quality shampoo, which does not contain conditioners that protect the scalp.

④ Use functional shampoos incorrectly, such as anti-dandruff shampoos, dyeing shampoos, etc.
