Will using talcum powder to absorb oil from hair harm the scalp?

Generally, occasional and minimal use of talcum powder to absorb hair oil may not harm the scalp, but frequent or excessive use can easily cause damage. If in doubt, it is recommended to consult a doctor in advance. Detailed analysis is as follows:

If the scalp is healthy, infrequent and minimal use of talcum powder for emergency oil absorption—followed by thorough washing afterward—typically does not harm the scalp. The absorbent effect of talcum powder can temporarily reduce the greasy feeling of hair; when exposure is brief and proper cleansing is performed, irritation to the scalp is minimal and discomfort unlikely.

However, if the scalp is sensitive or has wounds, or if talcum powder is used frequently and in large amounts without timely cleaning, scalp damage is more likely. Talcum particles may clog hair follicles, impairing their normal respiration and metabolism. They may also irritate the scalp, causing dryness, itching, or even worsening scalp inflammation. Long-term use under such conditions can disrupt the scalp's healthy environment.

When using talcum powder to absorb hair oil, apply sparingly and avoid areas with scalp injuries. Hair and scalp must be thoroughly washed on the same day of use. If itching or redness occurs, discontinue use immediately and seek medical advice when necessary.
