Nylon vs Boar Bristle Hair Brushes: How They Differ

Nylon bristles are smooth, firm and widely spaced, so they pass through hair easily and are good at detangling, including on thick or wet hair. Boar bristles are natural, dense and slightly rough, so they grip the hair's surface and are good at smoothing and at spreading the scalp's natural oil along the hair. Nylon is the practical choice for getting knots out. Boar is the finishing choice for polish.

Nylon vs boar bristle at a glance

What are nylon bristles good at?

• Detangling. Smooth, individual pins separate knots without holding on to them.
• Thick, long and curly hair. The bristles are stiff enough to get through to the scalp.
• Brushing with conditioner in. Synthetic bristles are not harmed by water or product.
• Easy care. They wash and dry quickly.

Quality varies. Look for bristles with rounded or ball tips, which feel comfortable on the scalp. Sharp, cut ends can scratch.

What are boar bristles good at?

• Smoothing the surface. The dense bristles lay the outer layer of the hair flat, which makes it look glossier.
• Distributing natural oil. They carry oil from the roots toward the drier ends, so roots look less oily and lengths less dry.
• Taming flyaways on dry, styled hair.
• Fine to medium hair, which the bristles can pass through easily.

On very thick or tightly curled hair, pure boar bristles tend to skim the surface without reaching the layers underneath.

Which one suits your hair?

• Fine, straight hair: boar for smoothing, or soft nylon for gentle detangling.
• Medium hair: either. Many people detangle with nylon and finish with boar.
• Thick or coarse hair: nylon, or a mixed-bristle brush.
• Curly or coily hair: nylon on wet, conditioned hair. Avoid dry brushing.
• Tangle-prone hair of any type: nylon first.
• If you avoid animal products: nylon.

What about mixed-bristle brushes?

Some brushes combine the two: longer nylon pins to get through the hair and detangle, surrounded by shorter boar tufts to smooth. They are a useful middle ground for thick hair that still wants the polish of boar bristle.

A nylon bristle cushion brush

The Uexim air cushion nylon bristle detangling hairbrush has soft nylon bristles set in an air cushion base, for detangling and scalp massage. The listing says it works on straight and curly hair, wet or dry, and describes it as anti-static. It is made of plastic and comes in three styles, A, B and C.

How do you use each type well?

Nylon

1. Start at the ends and work upward in sections.
2. Hold the hair above a knot so the pull does not reach the scalp.
3. On wet hair, use conditioner or a detangling spray for slip.

Boar

1. Detangle first with a comb or nylon brush.
2. On dry hair, brush from the scalp to the ends in long, slow strokes.
3. Follow each stroke with your free hand to smooth the section.

How do you clean them?

• Both: remove loose hair after every use.
• Nylon: wash in warm water with a little shampoo, rinse and dry bristle-side down.
• Boar: wash the bristles briefly, avoid soaking a wooden handle, and let the brush dry fully, bristles down, away from direct heat.

Frequently asked questions

Is a boar bristle brush better than nylon?

Neither is better overall. Boar smooths and adds shine. Nylon detangles and reaches through thick hair.

Can I use a boar bristle brush on wet hair?

It is best kept for dry hair. For wet hair, use a brush that is described as suitable for it, or a wide-tooth comb.

Do nylon brushes cause static?

Any brushing can create static in dry conditions. A light leave-in product and not over-brushing help.

Do I need both?

Not necessarily. If your hair tangles, start with nylon. Add boar later if you want a smoother, glossier finish.

The bottom line

Choose nylon to detangle and to manage thick or wet hair. Choose boar to smooth and add shine on dry hair. If you want both jobs done, use them in that order.
