Bristle guide

What is the difference between horsehair, goat hair, tampico and synthetic bristle, and what is each one for? As a manufacturer who works these materials every day, here is what you need to know before you buy.

Why the bristle is the decision that matters

What makes a brush is not its body, it is its bristle. Fit three different bristles to the same wooden body and you get three different products: one combs a baby's hair, one scrubs your back, one cleans your shoes.

We have kept notes on customer complaints since 2021. The large majority come not from a manufacturing fault but from the wrong firmness being chosen. Sell a horse tail brush to an audience with sensitive skin and you will collect reviews saying it is too harsh. Sell goat hair to someone expecting a cellulite brush and they will say they felt nothing.

So before we talk about price, we talk about bristle.

Horsehair: mane and tail

Horsehair is the most widely used raw material in natural brushes. But horsehair is not one material. It behaves completely differently depending on where on the animal it comes from.

Horse mane

The long hair from the neck. Fine, flexible and medium firm. Press it and it springs back. This is the main material in dry brushing brushes and body brushes. It stimulates the skin without scratching it.

Colour runs from white to dark brown. White mane is scarcer and costs more, which is why white bristle brushes carry a higher price. Grizzled hair, our word for mixed tone bristle, gives a natural look and sells very well.

Horse tail

Thicker, stiffer and less flexible than mane. Cellulite brushes and back brushes are usually made from tail hair, or from a tail and mane blend.

It is the firmest animal bristle we work with. Right for a user who wants a strong effect and a massage feel. Not right for sensitive skin.

Blends

In practice many brushes are made from a mane and tail blend, which gives enough firmness while keeping some spring. We set the ratio according to what the product is for.

Goat hair

The softest bristle we work with. Fine, feather like and very flexible. Against the skin it offers almost no resistance.

Goat hair — the softest bristle we work with

That is why goat hair is used in baby brushes and face brushes. A baby's scalp and the skin of the face are far more delicate than the rest of the body, and horsehair does not belong there.

Goat hair has one drawback: being soft, it flattens when wet and takes time to recover its shape. It is at its best in dry use.

Tampico and plant fibres

Tampico is a fibre taken from the leaves of the agave plant, originally from Mexico. Its colour sits between golden and pale straw.

Its importance is this: it gives a firmness close to horse tail with no animal content. For a brand looking for a vegan product, this is the natural answer. It does not feel like plastic, it is a real plant fibre.

Its second advantage is water resistance. It does not soften as much as animal hair when wet, so it behaves more consistently in wet use.

Synthetic bristle

Made from nylon and similar polymers. It is not natural hair and there is no need to pretend otherwise, because it has real advantages of its own:

The drawback is feel. It does not give the soft, living contact that natural bristle gives the skin. Natural hair for a premium skin care line, synthetic for a wet bath product or a cleaning brush.

Loofah, sisal and mitts

Technically this group is not a brush and it does not appear on the grade gauge. Loofah is the inner structure of a ripened, dried gourd. Sisal is the fibre of another plant in the agave family.

Loofah and mitt — they do not brush, they scrub

These do not brush, they scrub. They work with water and soap and lift dead skin mechanically. The Turkish hammam tradition is built on this.

Because they are made for wet use, they have no wooden body to warp. If you want a product that will live permanently wet in a bathroom, this is the group.

Loofah comes as Turkish or imported. Turkish fibre is usually denser and firmer, imported fibre softer and more open.

Which bristle for which product

Dry brushing
Horse mane. Goat hair for sensitive skin, horse tail for a stronger effect.
Cellulite brush
Horse tail, or a tail and mane blend. Tampico if it has to be vegan.
Face brush
Goat hair, or a goat and horsehair blend. Pure horse tail is too firm for the face.
Baby brush
Goat hair. We do not recommend anything else.
Back and bath brush
Synthetic or tampico if it will mostly be used wet, horsehair for dry use.
Hammam and exfoliation
Loofah, sisal or a woven mitt. Not a brush group.
Shoes and clothing
Synthetic bristle. It is not a skin product, so natural hair is not needed.

How to judge a good brush

Four things to check when the sample is in your hand:

  1. Pull the tuft. Grip it and pull. A few loose hairs is normal, a clump is not. In a good brush the tuft is knotted in and sunk into the body, not stapled.
  2. Run your hand over the body. There should be no burr, sharp corner or unfinished sanding. On baby products this is critical.
  3. Look at the bristle tips. Good natural hair tapers naturally at the tip. Hair cut flat with scissors scratches the skin.
  4. Ask for samples from two different batches. A serious manufacturer can give you them. The smaller the difference, the better their production control.

Care and lifespan

The one thing that decides how long a natural bristle brush with a wooden body lasts is moisture:

Frequently asked questions

Which bristle is used for dry brushing?

Horse mane is the most common. It is medium firm and stimulates the skin without scratching it. Sensitive skin moves to goat hair, a stronger effect moves to horse tail.

Can a horsehair brush get wet?

It can, but it should not sit in water. Natural hair softens when wet and firms up again as it dries. The weak point is the wooden body. For wet use, tampico, synthetic bristle or loofah is better.

Is goat hair softer than horsehair?

Goat hair is softer. That is why baby and face brushes use it. Horsehair is livelier and more durable.

What is a vegan brush made from?

Usually tampico, the fibre of the agave plant, close to horse tail in firmness. Synthetic bristle and loofah are also vegan.

Is it normal for a brush to shed bristles?

A few loose hairs in the first uses is normal in natural bristle and stops quickly. Shedding in clumps is a manufacturing fault.

What is the minimum order?

Fifty pieces. In this trade the private label minimum is usually 500 to 1000. You can see the full range on the products page.
