头皮代谢周期约为14天。

每日新陈代谢自行剥落的老废角质约3-5层， 随着年纪增长、代谢机能或内外在因素转变，

加上清洁不当，易使老废角质堆积;定期净化老废角质，保护健康角质层，维护头皮环境健康。

The scalp renewal cycle is approximately 14 days.

Each day, about 3–5 layers of dead keratinocytes naturally shed through metabolism.

However, as we age, or due to metabolic changes and internal or external factors,

combined with improper cleansing, excess buildup of dead cells may occur.

Regular purification of these dead keratin layers helps protect the healthy barrier,

maintaining a balanced and healthy scalp environment.
