Haircut Schedule Calculator
Calculate ideal weeks between haircuts from growth rate, preferred length, and maintenance tolerance.
Works for short, medium, and long hair styles.
Haircut schedule calculation helps you plan maintenance visits based on your hair type, desired length, and how fast your hair grows.
The core formula:
Weeks Between Cuts = (Desired Extra Length + Trim Amount) / Weekly Growth Rate
Annual Cost = (52 / Weeks Between Cuts) × Cost Per Visit
What each variable means:
- Weekly Growth Rate — average human hair grows 0.3–0.4 mm per day, or about 1.25 cm (half an inch) per month
- Trim Amount — how much the stylist removes at each visit (typically 0.5–2 cm for maintenance trims)
- Desired Extra Length — how much you want the hair to grow before the next cut
Worked example: You want to keep your hair at a consistent short length. You like the look right after a cut and are willing to let it grow 2 cm before going back. Your stylist trims 1 cm each visit. Growth rate: 1.25 cm/month.
Weeks between cuts = (2 + 1) / (1.25 / 4.33) = 3 / 0.288 = 10.4 weeks ≈ every 10 weeks
At $45 per visit: Annual cost = (52 / 10) × $45 = $234/year
Typical schedules by hair goal:
- Short men’s cut (tight fade): every 2–4 weeks
- Medium men’s cut: every 4–6 weeks
- Women’s short/pixie: every 4–6 weeks
- Women’s shoulder-length: every 8–12 weeks
- Long hair, trims only: every 12–16 weeks
- Growing out: trim every 16 weeks to remove split ends without losing length
Curly hair shrinks significantly when dry — factor in shrinkage (20–50%) when estimating your visual length between cuts.
