TLDR Hair extensions can damage scalp health and cause hair loss, especially with prolonged use.
Hair extensions can negatively impact scalp health, especially in those with thinning hair, by causing traction alopecia, follicular stress, and barrier injury through various attachment methods like thermopolymer, adhesive, mechanical, and temporary. Adhesives may lead to allergic reactions and barrier disruption, while thermal bonding can harm hair fibers. Prolonged use can alter the scalp's microbiome, increasing inflammation. Preventive measures include limiting extension weight, using less sensitizing adhesives, and maintaining proper scalp care. Early intervention with strategies like reducing traction and applying anti-inflammatory treatments is essential to prevent irreversible damage.
