Hairbrushes have a lifespan of six months to one year, hairstylist and VaultBeauty expert Elizabeth Hickman told Real Simple. This range depends on the number of hair products you use. Sabit Hantal, hairstylist and founder of SH Fifth Avenue Salon, told Byrdie that high-end brushes might last as long as a few years. These pricier brushes frequently have heat-resistant bristles, which helps extend their life.
Suppose you notice your brush's bristles are separating. In that case, it's an early sign that it's time to replace the brush, according to Marc Anthony, hairstylist and founder of Marc Anthony True Professional Haircare (via Women's Health). Anthony suggests using argan oil on brush bristles to help preserve them. Once bristles become broken or missing, it's time for a replacement. These damaged bristles can lead to damaged hair, according to Elisa Fitzpatrick, a senior stylist at SEVEN Salon in Seattle (via Today). Blowdryers can also cause bristles to melt or fall out. If more than 10% of bristles are missing, or the hair brush's bed is cracking, it's time for a new brush. When it's time to say goodbye to your brush, it can't be recycled. Unlike plastic combs, hairbrushes are made of multiple materials, including glue and sealant, which prevent them from being recycled (via Can You Throw It Away).
