Brow soap

Brow soap holds a brow more firmly than a gel, without a trip to the salon. It comes as a small bar, a tin or a pot of clear soap or soap-like wax; a spoolie, dampened with water or a mist, is rubbed across the surface to pick up a thin film and then brushed straight up through the hairs. As it dries it grips them where they stand, stiff enough to keep a fanned, feathered shape through the day. Many products sold as brow soap are in fact waxes, and the name describes the look as much as the ingredients.

Against a clear gel it gives more grip and more texture: a gel smooths the hairs, where soap separates and lifts them and leaves a drier finish. A pomade colours as it holds; brow soap is almost always clear. And unlike brow lamination, a salon perm, it washes off at night. Because it opens the brow out, it is often paired with a pencil or pen to fill the gaps that the brushed-up hairs reveal.

Start with clean, dry brows, and wet the spoolie only slightly, with a spritz of water or setting spray; a dripping brush dissolves too much soap and dries to a white film. Rub it back and forth across the surface a few times. Brush the brows straight up from the front, pressing the hairs flat against the brow bone with the side of the brush, then work outward along the arch, angling the hairs a little, and comb the tail along its natural line. Let it dry for a minute before touching it.

Fill sparse patches afterwards with light pencil strokes or a brow pen, drawn in the direction the hairs now point; powder put on first tends to lift away with the soap. If flakes appear during the day, the usual cause is too much product or too little water: brush through with a clean, dry spoolie and use less next time. At night, brow soap comes off with warm water and an ordinary cleanser, though the waxier formulas may need an oil.

How far to brush the hairs up depends on the brow. Thick, straight brows take the full fanned look from the front to the arch; on sparse or fine brows it shows the skin between the hairs, so brush up only the front third and let the rest lie along its line. The tail almost always sits better combed flat, out towards the temple.

Formulas differ in how firmly they grip, how clear they dry and how readily they flake. True soaps are woken with water and give a firm, matte hold. Waxes grip harder and flake less, can look slightly glossy, and some are sold with their own activating mist. A few come in sheer tints as well as clear, adding a little colour to the hold, which suits pale brows that disappear once brushed up. If the skin around your eyes reacts easily, choose an unscented formula and try it on a small patch first.

Keep to a product sold for the brows. The FDA’s advice for eye cosmetics is not to use any cosmetic near the eyes “unless they are intended specifically for that use”, and a bathroom soap is not.^[1] An open soap also collects whatever the brush carries back to it, so wash the spoolie often or use a clean one, keep the lid on, and never share the tin; not sharing eye cosmetics, and keeping their containers clean, is the FDA’s advice too.^[1]

Soap has held hair in place for well over a century. Nineteenth-century perfumers sold water cosmetique, pigment milled into soap and put on with a small wet brush; water cosmetiques, like greasy ones, were used to fix hair in place, and the pigmented kinds were sold mainly to men to darken beards and moustaches. In 1855 the perfumer G. W. Septimus Piesse described Rimmel’s as “a nicely-scented soap strongly colored with lamp-black or with umber”, and a guide of 1904 judged that for pencilling eyebrows nothing was “more easily applied or removed”.^[2]

The clear soap brow of today comes with a family story. In 2016, by the family’s account, Kim Cattin, a make-up artist from Sunderland working on the set of Game of Thrones, asked her mother, Donna McCann-Turner, to make something that would keep brows in place. The result, Soap Brows, was “a wax”, poured by hand in Donna’s kitchen and taken up at London Men’s Fashion Week. Donna has said that the stars of old Hollywood films “would use soap to lift their brows”, a story we have not been able to check.^[3] The British trade mark SOAPBROWS is dated 18 April 2017; the American registration, granted in 2019, was cancelled in February 2026 for want of an acceptable declaration of use.^[4]

By then the look belonged to everyone. In January 2021, by Glossy’s account, Anastasia Soare set out to answer the flaking that dried soap left on brows, then “a massive social media trend”, and launched Brow Freeze, which Glossy, citing NPD, called the best-selling brow wax.^[5] Drugstore houses now sell soaps of their own, and West Barn Co is selling the last of the original. The brushed-up brow it made fashionable has outlasted the tin.
