Introduction
Itching and dandruff on the scalp after washing hair with white vinegar may be caused by physiological factors, or pathological conditions such as pityriasis capitis or seborrheic dermatitis. Treatment can be achieved through general care or medication. Seborrheic dermatitis may result from increased sebaceous gland secretion, which damages the skin's immune barrier and causes dilation of cutaneous capillaries, leading to excessive dandruff formation.
Itching and dandruff on the scalp after washing hair with white vinegar may be caused by physiological factors, or pathological conditions such as pityriasis capitis or seborrheic dermatitis. Treatment can be achieved through general care or medication. Specific details are as follows:
I. Physiological Factors
This is usually due to incorrect usage, such as using vinegar that is too concentrated, which irritates the scalp and causes itching. Special treatment is generally not required; symptoms can be relieved by washing the hair more frequently.
II. Pathological Factors
1. Pityriasis Capitis (Scalp Seborrhea)
This may result from infections such as Malassezia or Propionibacterium acnes, leading to chronic skin inflammation. Symptoms include itchy scalp, excessive dandruff, and hair loss. Under medical guidance, treatments may include antifungal agents like ketoconazole shampoo or sulfur ointment.
2. Seborrheic Dermatitis
This may occur due to increased sebaceous gland secretion, which damages the skin's immune barrier and causes capillary dilation, resulting in flaky scalp. Under a doctor’s supervision, treatment may involve topical application of compound acetic acid dexamethasone cream or oral administration of vitamin B2 tablets.
In addition to the above, conditions such as tinea capitis, tinea corporis, or psoriasis may also be responsible. Avoid scratching with hands and maintain cleanliness of the affected area.
