New Delhi, Feb 17: Hair extensions, popular for adding glamour, length, and volume, may pose serious health risks due to toxic chemicals, according to a recent global study published in Environment and Health. Both synthetic and natural extensions may contain benzene, formaldehyde, and phthalates, which are linked to cancer, hormonal disruption, and respiratory problems.

Key findings from the global study

• 44 hair extension samples were tested for chemical exposure.

• Hazardous compounds detected included volatile organic compounds (VOCs), endocrine disruptors, and carcinogens.

• Prolonged scalp contact, combined with heat styling, increases chemical absorption.

• Findings highlight regulatory gaps in the beauty and hair extension industry.

Implications for Indian consumers

• India is a major market for natural hair extensions, with Tamil Nadu and Andhra Pradesh as key suppliers of temple hair.

• Lack of transparent labelling leaves consumers unaware of chemical treatments applied during processing.

• Even donated hair may undergo chemical processing before commercial sale.

• Salon adhesives and bonding agents may contain formaldehyde or toluene, causing scalp irritation and long-term effects.

• AIIMS Delhi (2023) reports rising cases of contact dermatitis and respiratory allergies among salon workers.

Health risks associated with hair extensions

• Cancer: Benzene and formaldehyde are recognized carcinogens.

• Hormonal disruption: Phthalates may affect endocrine function and fertility.

• Respiratory problems: VOCs released during heat styling can trigger asthma and chronic cough.

• Skin issues: Adhesives and chemical coatings may cause dermatitis, itching, and scalp inflammation.

• Traction alopecia: Continuous pulling from extensions can lead to hair loss.

Expert advice for safe use

• Choose extensions from reputable sources to minimize chemical exposure.

• Give your scalp regular breaks to reduce cumulative damage.

• Remove clip-in extensions before sleeping to avoid tangling and frictional damage.

• Be cautious with tape-in or permanent extensions, which carry higher chemical and traction risks.

• Use protective measures like gloves during salon treatments to prevent allergies.

Call for regulation in India

• India’s hair extension market, valued at over INR 250 crore, is largely unregulated compared to Europe.

• Experts urge mandatory labelling, stricter safety oversight, and consumer awareness campaigns.

• Public and occupational health risks affect both users and salon workers, highlighting the need for urgent intervention.
