When should you get a haircut?
Get a haircut every 4–6 weeks for short hair, every 8–10 weeks for mid-length, and every 10–12 weeks for long hair. Signs you're overdue: stringy or wispy ends, styling taking longer than usual, layers looking flat, or products no longer absorbing into damaged ends. Even when growing hair out, trim every 3 months to prevent damage.
Most people wait too long between haircuts and notice hair feels 'off' without knowing why. Here are the five clear signs you're overdue for a cut, and how often each hair type and length actually needs a trim to stay its best.
How Often You Actually Need a Haircut
Short hair (pixie, bob): every 4–6 weeks. The shape loses definition quickly and a trim keeps it looking styled. Mid-length hair: every 8–10 weeks. Balances shape maintenance with growing out. Long hair: every 10–12 weeks minimum for a dusting, 12–14 weeks for a proper trim. Curly hair: every 10–12 weeks regardless of length — dry cutting every few months keeps curl shape intact. Damaged or colour-treated hair: every 6–8 weeks to stop split ends travelling up the shaft.
Sign 1: Ends Feel 'Stringy' or Wispy
Healthy ends feel the same density as mid-lengths. When the ends feel thinner, stringy, or wispy — that's split ends travelling up the hair shaft. Once splits start, they get worse until cut off. Waiting an extra month means losing an extra inch when you finally book.

Sign 2: Styling Takes Longer or Doesn't Hold
Your hair knows the shape it was cut in. When that shape grows out, styling becomes harder — the blowdry takes longer, curls don't hold, the part won't sit. If your styling routine has quietly gotten longer over a few months, your cut is growing out.
Sign 3: Layers Look Flat or Undefined
Layered cuts rely on specific lengths to create movement. After 10–12 weeks, layers grow out and the cut looks blunt or shapeless. If your hair looks 'flat' when you used to have movement, that's a cut signal.
Sign 4: You Can't Remember When You Last Booked
If you can't remember your last haircut date, you're overdue. Track it in your phone calendar. For most people, 10–12 weeks is the upper limit before hair health starts to decline.

Sign 5: Hair Feels Dry and Products Don't Work
Damaged ends don't absorb product. If your conditioner, leave-in, or mask feels like it's sitting on your hair instead of absorbing, the ends are damaged enough that they can't hold moisture anymore. Only a cut fixes this — no treatment brings damaged hair back.
Don't Grow Out Hair Without Trimming
The biggest mistake when growing hair: skipping trims entirely. Ends split, splits travel up the shaft, and eventually you have to cut more to remove damage than if you'd trimmed every 10–12 weeks. Even growing hair needs a 1cm trim every 3 months to stay healthy. Mention 'dusting — just the ends' and a good stylist will trim minimally.

Frequently Asked Questions
What's the best treatment for frizz in humid Sydney weather?
A keratin-free smoothing treatment paired with a humidity-resistant leave-in works best for Sydney's changeable climate. Start with a gentle, sulphate-free wash, add a protein-balanced mask weekly, then seal with a heat-activated protectant before blow-drying.
How often should I tone blonde hair at home?
Every 1–2 weeks for maintenance, using a pH-balanced violet or blue-violet treatment, depending on your undertone. Keep dwell time short (3–5 mins) to avoid over-ash. Follow with a hydrating mask because toners can be slightly drying.
Keratin vs. smoothing: which lasts longer?
Keratin treatments (formaldehyde-free) generally outlast quick smoothing services, giving 2–4 months of frizz reduction with proper care. Smoothing services are gentler and great for first-timers or colour-treated hair, lasting 4–8 weeks.
