What should I do about dry scalp and excessive dandruff?

Scalp dryness and excessive dandruff refer to abnormal hyperproliferation of the stratum corneum of the scalp, leading to the shedding of keratinized cells as white or grayish flakes. Under normal physiological conditions, visible flaking is typically absent; however, pathological dandruff—often triggered by inflammation, infection, or other underlying conditions—may result in a marked increase in visible dandruff.

What Can Be Done for Scalp Dryness and Excessive Dandruff?

1. Medication

Excessive dandruff may stem from fungal infection or deficiencies in trace elements. If over-the-counter anti-dandruff shampoos prove ineffective, oral supplementation with B-complex vitamins or selenium may help alleviate symptoms. In cases associated with Malassezia (formerly Pityrosporum) infection or seborrheic dermatitis, antifungal therapy or measures to regulate scalp sebum production are recommended. Excessive dietary fat intake can stimulate sebaceous glands to overproduce sebum, thereby accelerating dandruff formation and worsening the condition.

2. Dietary Adjustments

Increasing intake of alkaline foods may help reduce dandruff. Scientific research suggests that dandruff is linked to systemic fatigue; fatigue impairs metabolism, causing acidic metabolites—including lactic acid, uric acid, and phosphoric acid—to accumulate in the body. These acids alter blood pH, contributing to fatigue and impairing nutrient delivery to the scalp. Consuming alkaline foods helps restore acid-base balance.

3. Daily Scalp Care

Wash hair regularly with warm water, avoiding strongly alkaline shampoos, as these can irritate scalp epidermal cells and exacerbate dandruff. Scalp massage and regular brushing—two to three times daily, morning and evening—can improve scalp circulation, enhance hair nutrition, promote hair growth, and reduce abnormal keratinization of epidermal cells. Additionally, rinsing hair with diluted vinegar (followed by thorough rinsing with clean water) several times may effectively remove dandruff. This practice may also help prevent hair loss and reduce split ends.

The above outlines practical approaches to managing scalp dryness and excessive dandruff. We hope this information proves helpful.
