Tweezers

What it is

Tweezers are a simple mechanical tool - two spring-tensioned arms meeting at a tip - used to grip and pull individual hairs out at the root, most commonly for shaping eyebrows but also for other small facial or stray hairs. Unlike trimming, removal at the root means regrowth takes longer to become visible.

How it works

Removing hair at the root, rather than cutting it at the surface, delays regrowth because the follicle has to cycle back into an active growth phase before a new hair reaches the surface. Repeated removal from the same follicle over time can also cause some hairs to grow back finer or less consistently, which is part of why shaping brows gets easier to maintain the longer it's kept up.

How to choose one

• Slanted-tip tweezers are the most versatile shape, suited to both grabbing single hairs and sweeping through several at a shallow angle.
• Pointed-tip tweezers offer the most precision for ingrown hairs or very fine, stray hairs, but are less forgiving for general shaping.
• Check the tip alignment before buying - the two tips should meet exactly flush; misaligned tips slip past hairs instead of gripping them.

Common mistakes

• Removing hairs above the natural brow line to "shape," which is much harder to correct than removing more from below over time.
• Plucking in bright, harsh lighting without checking the shape from a distance, leading to over-thinning that isn't obvious until it's done.
• Using dull or misaligned tweezers, which increases the chance of breaking a hair instead of removing it at the root - breakage causes stubble regrowth much sooner than a clean pull.
