In skincare products, formaldehyde is frequently utilized as a preservative. It is a colorless gas that stops germs from growing. Products that include formaldehyde include nail polish, hair gels, nail hardeners, shampoos, deodorants, lotions, and cosmetics. It is linked to neurotoxicity, scalp burns, hair loss, developmental toxins, and asthma.
Formaldehyde levels in personal care products, such as shampoos, are generally “far below hazardous” to human health, according to the American Cancer Society. According to the group, keratin hair smoothing procedures have the potential to dangerously increase indoor air concentrations.
