Does baby powder work for oily hair?
Generally, baby powder can remove excess oil from hair to a certain extent, but its oil-absorbing effect is typically not long-lasting. A detailed analysis follows:

Baby powder is a commonly used topical powder primarily intended for the prevention and treatment of prickly heat (miliaria) and heat rash. Its main ingredients include talcum powder, zinc oxide, salicylic acid, and menthol, which collectively confer properties such as wind-dispersing, dampness-resolving, cooling, antipruritic (itch-relieving), and skin-drying effects. Notably, talcum powder possesses strong adsorptive capacity and can absorb excess sebum and sweat from the skin or hair. Due to this adsorptive property—particularly of talcum powder—baby powder can partially absorb excess oil from hair. However, this oil-removing effect is short-lived. Moreover, excessive or improper use may leave visible white powder residue on the scalp, compromising aesthetic appearance.
Additionally, frequent use of baby powder to control hair oil may disrupt the scalp’s natural sebum balance, potentially leading to dryness, itching, and other scalp issues. After applying baby powder, it is essential to thoroughly cleanse both the scalp and hair to prevent powder residue. In daily life, maintaining healthy habits—including a balanced diet, regular sleep patterns, and proper hygiene—is crucial. Concurrently, selecting an appropriate oil-control shampoo for routine hair washing is recommended.
