What Causes White Patches on the Scalp? Is It Normal?

Hair graying is often considered a normal phenomenon, but it can also be caused by malnutrition, albinism, vitiligo, and other reasons. It is recommended to seek medical attention for diagnosis and treatment under the guidance of a doctor. Here are some possible causes:

With age, the various tissues and organs of the body decline, and the function of melanocytes gradually deteriorates. Clinically, this often manifests as hair graying, which is a normal phenomenon and generally does not require special treatment. Routine care is sufficient.

Improper diet and lack of trace elements can affect body metabolism, often leading to melanin synthesis disorders and accompanied by hair graying. It is recommended to maintain a healthy diet, ensure adequate nutrition, and appropriately supplement vitamins and trace elements.

Family history and genetic mutations can lead to melanin production disorders. Clinically, this often manifests as melanin deficiency accompanied by changes in skin and hair color. Patients need to take good care of their skin under the guidance of a doctor, avoid sun exposure, and rest adequately.

Autoimmune diseases, genetic factors, and exposure to harmful substances can affect the normal physiological function of the skin, often leading to primary, localized, or generalized skin and mucosal pigment loss. Patients need to use drugs such as mometasone furoate cream, tacrolimus ointment, and prednisone acetate tablets under the guidance of a doctor to restore partial skin color. It is also important to protect the skin from the sun, avoid skin trauma, and wear cotton, loose, comfortable, and breathable clothing.

Besides the above reasons, phenylketonuria can also lead to hair graying, which is often caused by genetic abnormalities and family history. It usually results in phenylalanine accumulation and abnormal metabolism in the body, clinically manifesting as hair graying, abnormal skin color, and other symptoms. It is recommended to adjust the diet under the guidance of a doctor, eat more vegetables and fruits, and alleviate the symptoms through cell-directed therapy.
