Dandruff is associated with an acidic scalp pH. This means that the scalp's pH level is below 7.
A normal scalp has a slightly acidic pH, ranging from 4.5 to 5.5. This acidic environment helps to maintain the scalp's natural barrier, which protects it from bacteria and other microorganisms. However, in individuals prone to dandruff, the scalp may become more acidic. This can create a favorable environment for the growth of Malassezia globosa, a type of fungus that is commonly associated with dandruff.
Factors contributing to an acidic scalp:
- Excess sebum production: Oily scalps tend to be more acidic.
- Use of harsh shampoos and hair products: These products can disrupt the scalp's natural pH balance.
- Stress and hormonal changes: These factors can also affect the scalp's pH level.
Tips for balancing scalp pH:
- Use pH-balanced shampoos: These shampoos are designed to maintain the scalp's natural pH.
- Avoid using harsh hair products: Look for products that are sulfate-free and paraben-free.
- Keep your scalp clean: Wash your hair regularly to remove excess sebum and dead skin cells.
- Use a scalp scrub: A scalp scrub can help to exfoliate the scalp and remove buildup.
