Eyes, Brows, Lashes

Eyebrow shaping: three points, one arch

Eyebrow shape is not a matter of taste alone: three fixed points, set by the angle of the nose and eye, decide where a brow should start, peak and end. The starting point sits directly above the inner corner of the eye, the highest point on a line from the edge of the nostril across the outer edge of the iris, and the end point on a line from the nostril to the outer corner of the eye. Hair removed from any of these areas takes 6 to 8 weeks to grow back to its original length, so it pays to measure before reaching for tweezers.

Measuring the three points

A brow pencil, a thin brush handle or a cotton bud held flat against the face works as a straight edge for all three points. Held vertically at the inner corner of the eye, it marks where the brow should begin; angled from the edge of the nostril across the outer edge of the iris, it marks the highest point of the arch; angled again from the nostril to the outer corner of the eye, it marks where the brow should end. None of the three lines are rules to follow to the letter: moving the highest point 2 to 3 millimetres further out softens the arch, moving it inward sharpens the expression, and either choice depends on the face in the mirror, not a formula.

What gets left in place matters as much as what gets removed. A brow tweezed down to a thin line makes the eyes look smaller and the whole face read as older, and the hair does not come back quickly: after a complete pluck, regrowth to visible length takes 6 to 8 weeks, and after years of daily over-plucking, some follicles stop producing hair at all. Marking the three points first and removing only what sits clearly outside them is the difference between a shape that holds for weeks and one that needs rescuing with a pencil every morning.

Threading, tweezing, waxing and trimming compared

Tweezing removes one hair at a time and suits fine correction between appointments; a touch-up with tweezers alone typically takes 5 to 10 minutes and is repeated every 2 to 3 weeks to keep a shape crisp. Threading lifts whole rows of fine hair with a twisted cotton thread, so a full pair of brows is usually done in 10 to 15 minutes with a straighter edge than tweezers alone produce. Waxing works well for the overall shape and clears larger areas in 5 to 10 minutes, but the lower edge of the brow can sit only about 1 centimetre above the lash line, where the eyelid skin is thin enough that not every technician will wax that close; some limit wax to the area above the arch and finish the lower edge with thread or tweezers.

Trimming is the one technique that does not remove hair from the root: long strays are combed upward and the tips cut back a couple of millimetres, which shortens the brow without thinning it. Combining methods tends to hold a shape longest: threading or waxing sets the outer line, tweezers handle the 2 to 3 week touch-up, and trimming keeps stray hairs from curling out of formation in between. A single threading or waxing session for both brows commonly costs $10 to $30 depending on the salon and city, a fraction of the price of a full-face wax.

Before a full reshape

A shape drawn first in pencil and checked in a mirror, before a single hair falls, is the clearest sign of a technician working to a plan rather than habit. It also gives a chance to move the highest point in or out before the choice sets the line for the next 6 to 8 weeks. Skin that is sunburnt, freshly peeled or recently treated with a laser on the face should not be tweezed or waxed at all until it has settled, since the surface is thinner and marks or tears more easily than usual. The same goes for an active eye infection such as conjunctivitis or a stye, or any broken or infected skin along the brow line: tools and thread pass close enough to the eye to spread it further, so shaping should wait until it has cleared.

Anyone taking isotretinoin for acne should say so before booking: UK dermatology guidance advises against waxing and epilation during treatment and for up to 6 months afterwards, because the medicine leaves skin more likely to scar or discolour under the pull of a strip. Any hair removal method, tweezing and threading included, can trigger folliculitis, a rash of small, usually sterile bumps where a hair is regrowing; dermatologists advise waiting about 3 months after it has settled before hair removal starts again in that spot. Anyone trying a new wax or tint product for the first time is better off with a patch test 48 hours beforehand, checked again a further 48 hours later, since most allergic reactions surface within that 96 hour window.

Filling gaps and keeping the shape

Between full reshapes, a brow pencil, powder or tinted gel fills sparse patches for a single day and washes off with cleanser, which is the lowest-risk way to test a fuller shape before committing to anything permanent. Tinting the hair itself, rather than the skin, darkens what is already there and typically lasts 4 to 6 weeks before it needs repeating, with no hair removed and nothing to regrow.

For a shape that lasts months rather than weeks, semi-permanent techniques such as microblading deposit pigment along the three points instead of filling them in each morning; a set typically holds its colour for 12 to 18 months before it needs a touch-up, with a shorter refresh often booked at 4 to 6 weeks to settle patches that faded unevenly. None of these fixes change the underlying rule: the three points set the frame, and everything else, tweezers, thread, wax, pencil or pigment, works inside it.

Questions to ask before a full reshape

Frequently asked

Where exactly should eyebrows start and end?

The start sits directly above the inner corner of the eye and the end on a line from the edge of the nostril to the outer corner of the eye. The highest point of the arch sits on a line from the nostril across the outer edge of the iris.

How long does it take for eyebrows to grow back?

About 6 to 8 weeks for a fully plucked brow to return to its original length. After years of daily over-plucking, some follicles stop producing hair altogether.

Is threading or tweezing better for eyebrows?

Threading lifts whole rows of fine hair at once and gives a straighter edge in less time, usually 10 to 15 minutes for both brows. Tweezing is slower but more precise, which makes it the better tool for touch-ups every 2 to 3 weeks.

When should eyebrows not be tweezed or waxed?

On sunburnt, freshly peeled or laser-treated facial skin, and during treatment with isotretinoin and for up to 6 months afterwards, since the skin is more likely to tear, scar or discolour.

Should I get a patch test before eyebrow tinting or a new wax?

Yes, especially the first time: the product is applied for 48 hours, then the skin is checked again 48 hours later, since most allergic reactions surface within that 96 hour window.
