Boar Bristle

Boar bristle consists of the natural hair from domestic pigs (Sus scrofa domesticus), and is softer and more flexible than plant fibers, making it gentle on the scalp and suitable even as a alternative to nylon toothbrush bristle. Quality varies significantly based on bristle length, thickness, and processing - premium boar bristle is longer, more flexible, and minimally processed.

For plastic-free living, boar bristle hairbrushes offer similar performance compared to plastic bristles while avoiding microplastic shedding and synthetic materials. Unlike nylon bristles that create static and can't distribute natural oils, boar bristles work with hair's natural properties to create shine, reduce frizz, and improve hair health over time. While boar bristle brushes cost 2-5x more than plastic alternatives and require more care, they provide genuinely superior results for hair health and eliminate the microplastic concerns of synthetic bristles.

Grooming and Hair Care: Brushes for hair, facial hair

Oral Care: Toothbrushes

Microplastic Concerns: Boar bristle does not shed microplastics. It is natural animal hair (keratin protein) that biodegrades completely into organic matter. Unlike plastic or nylon hairbrush bristles that shed microplastic particles during use (which can accumulate on scalp and in bathroom environments), boar bristle releases only biodegradable organic material.

Chemical Safety: Pure boar bristle is natural and chemical-free. However, some boar bristle brushes are bleached, dyed, or treated with chemicals during processing, making unbleached, undyed boar bristle ideal.

Certifications to Look For: Cruelty-free or ethical sourcing certifications (ensuring bristles are collected as byproduct of meat production, not from live animals). Unbleached/undyed designation for chemical-free bristles. Vegan alternatives exist (plant fiber or synthetic) for those avoiding animal products entirely.
