According to Dr. Sanjeev Gulati, Department of Dermatology, Sharda Hospital - Noida (India), dandruff is a condition in which the scalp produces and sheds skin cells at an abnormally fast rate, resulting in dry and flaky scalp in small white patches or spots. In some people, other symptoms may include: itchy scalp, irritation, redness on the scalp and scalp inflammation.
How does zinc help treat dandruff?
Zinc is a trace mineral that has many health benefits, including supporting immune function, skin health, and cell repair. Additionally, zinc is effective in treating dandruff, says Dr. Sanjeev Gulati.
Zinc helps regulate oil on the scalp: Zinc has the ability to control the production of oil on the scalp, one of the main causes of dandruff. When the scalp produces too much oil, it can create favorable conditions for the growth of malassezia fungus, leading to dandruff. Zinc helps reduce excess oil, thereby limiting the growth of fungus and preventing dandruff.
Anti-inflammatory and antibacterial: Zinc has strong anti-inflammatory and antibacterial properties, which help reduce inflammation and irritation of the scalp. This can soothe symptoms of itching, redness, and flaking, which are common signs of dandruff.
Helps Clean the Scalp: Zinc also helps clean the scalp by removing dead cells. When the scalp is no longer filled with dead cells and excess oil, dandruff will be significantly reduced.
Improves hair and scalp health: Zinc is essential for the growth of new cells, including those on the scalp. When the body has enough zinc, the scalp and hair will be healthier, helping to prevent the appearance of dandruff caused by dry and damaged scalp.
Reduces the risk of fungus and bacteria: Zinc has the ability to reduce the growth of Malassezia fungus, one of the main causes of dandruff. Using zinc products or adding zinc supplements to your diet can help prevent dandruff from recurring.
Ways to supplement zinc to treat dandruff:
Use a zinc shampoo: Shampoos containing zinc pyrithione or zinc oxide are effective dandruff treatment options. These shampoos not only reduce dandruff but also protect the scalp from bacteria and fungi.
Supplement zinc through diet: Zinc-rich foods such as red meat, seafood, beans, chia seeds and whole grains can help provide enough zinc for the body.
Zinc supplements through tablets: If your diet does not provide enough zinc, you can consider zinc supplements through tablets (as prescribed by your doctor).
