Ask a Pro: How Often Should I Really Trim My Hair?

If you’ve ever been told you “must” trim every six weeks, you’re not alone. It’s one of the most repeated rules in hair — and one of the most misunderstood.

There isn’t a single schedule that suits everyone. Trim timing depends on your hair’s condition, your styling habits, and whether your ends are prone to splitting.

What trims actually do

A trim maintains your perimeter thickness, removes splits before they travel, improves shape, and helps hair look healthier. But trims don’t change your growth rate — they protect your length from breaking off.

The real variable: breakage vs retention

Hair grows roughly 1–1.5 cm per month. If your ends are breaking faster than that, you’ll feel like you’re going nowhere — even when you are growing.

Trimming removes the weak point so the remaining length can retain. That’s why some people see more length after trimming regularly: less breakage means better retention.

Colour-treated hair usually needs more maintenance

Lightening increases porosity and weakens the cuticle. That makes ends more prone to splitting, especially with heat styling.

If you lighten frequently, you may benefit from smaller, more frequent trims rather than waiting until ends are visibly frayed.

Natural, low-heat hair can often go longer

If your hair is rarely heat styled, not chemically processed, and you’re gentle with brushing, you may be able to trim less often — focusing on signs instead of dates.

Signs it’s time for a trim

Look for: tangles that appear suddenly at the ends, a see-through perimeter, more snapping during brushing, roughness that doesn’t improve with conditioning, and visible splits.

When you’re unsure, ask a pro

If you’re trying to grow your hair but fear that trimming will set you back, a professional can map out a plan that protects length without over-cutting.

HUSLBeauty’s Find A Pro helps you connect with trusted stylists around Australia for consultations, trims and personalised maintenance advice based on your area.

The takeaway

Trim based on condition, not habit. Small, strategic maintenance protects your ends, preserves your shape, and supports long-term length retention — without unnecessary loss.
