The scalp, as the "soil" for hair growth, directly determines the quality of the hair. A healthy scalp has a stable bacterial flora and acid-base balance, with a pH value usually between 4.5 and 5.5.

Once this balance is disrupted, it can cause problems like dandruff and itching. At the same time, the imbalance of scalp oil secretion, excessive sebum will block hair follicles, affect the normal growth of hair, and then lead to problems such as hair loss. In addition, factors such as environmental pollution, mental stress, and bad living habits can also damage the scalp's barrier function and exacerbate scalp problems.
