Features

Air Goes Through, Not Around
Open honeycomb vents let your dryer's airflow pass through the barrel, so hair dries from inside and outside at once. Fewer passes, less heat on your ends.

Grip That Smooths
Boar tufts hold the section under steady tension and lay the cuticle flat while the nylon pins keep strands separated. Frizz smooths out as it dries.

Clean Release Every Time
With no seam at the neck, hair rolls off the ends in one smooth motion. Nothing catches, nothing tears.
Even Ceramic Heat
The nano-titanium ceramic barrel spreads dryer heat evenly, so curves set smoothly without hot spots that frazzle your ends.
Less Static, More Shine
Ionic nylon pins and natural boar bristles help tame flyaways and leave a soft, glossy finish.
Honeycomb Vented Barrel
Hexagonal vents open about 62% of the barrel, so dryer air passes through the core and dries each section from both sides.
Dual-Height Bristles
Short natural boar tufts smooth and grip. Taller ball-tipped ionic nylon pins part thick sections without scratching your scalp.
One-Piece Snag-Free Neck
Barrel and handle meet in one smooth molded curve. No metal ring, no gap, nothing for hair to wrap into.
98g Balanced Handle
Light enough for thick, long hair. The matte textured grip turns easily between your fingers, even with oil on your hands.
How to use it
- 1
Rough-Dry and Section
Dry your hair to about 80%, clip the top layer up, and place the brush under a 2-inch section at the root for lift.
- 2
Glide With the Dryer
Pull the brush slowly down the section with steady tension while you aim the dryer nozzle down along it. Two or three passes is usually enough.
- 3
Cool and Release
Hit the cool shot for a few seconds, then roll the brush off the ends. You'll get a smooth, bouncy curve and no hair left in the brush.

Care & safety
- Clean weekly if you use styling products: comb out loose hair, soak the bristles in warm water with a drop of shampoo for about a minute, wipe with a comb, and rinse.
- Let it air-dry with the bristles facing down so water doesn't sit in the barrel. Avoid leaving it on a hot dryer or in direct sun for long periods.

Questions
What hair lengths work with a 55mm barrel?
Chin-length bobs, shoulder-length layers, and long hair. It gives lift on long hair and smooth bevelled ends on medium hair. Cuts under about 4 inches are too short to wrap.
How heavy is it?
98 grams, about a third lighter than solid wood boar brushes, so your wrist and shoulder hold up through a full head.
How do I clean product buildup out of the boar bristles?
Pull out loose hair with a comb, soak the bristles for a minute in warm water with a little shampoo, wipe them with the comb, and let the brush air-dry bristles down.
How much is shipping?
Shipping to the US is free and tracked. You get a tracking number by email when your order ships. See the shipping policy for delivery times.
Can I return it?
Yes, within 30 days of delivery. Details are in our refund policy.
