When Not to Cut Your Hair, and Why
Avoid Wednesday, and many also avoid Buddhist holy days.
Wednesday: old texts say a Wednesday haircut makes fortune slip away; a popular explanation is that barbers of old took Wednesday off
Buddhist holy days: days of precepts, so many households skip haircuts and nail trims
At night: the same belief as for nails; the real reason was poor light
Many barbers open on Wednesdays today; cut whenever suits you, it is a personal belief.
Haircut vs Nail-Cutting Days at a Glance
Sunday, Monday and Friday are good for both. Wednesday suits nails but not hair; Tuesday, Thursday and Saturday suit hair but not nails.
There are 4 holy days a month. If you avoid haircuts on them, check before booking. Remaining 2026 dates: Oct 4, 11, 19, 26; Nov 3, 9, 17, 24; Dec 2, 9, 17, 24.

Pick Your Style Before the Appointment
Pick a style and save a photo to show the stylist, so you get it right the first time. Ideas with 4-angle photos:
Give the length you want in centimetres, and mention any colour, perm or straightening in the last 3 months.
Book the appointment early in the day if you can: the stylist is fresh, the light is good for checking the shape, and you have time to wash and restyle at home before evening plans. If you are growing your hair out, ask for a dusting trim that removes only the split ends instead of a full reshape, so length keeps building between visits.
Hair and Scalp Care After a Cut: A Pharmacist's Tips
A fresh cut lasts longer with a clean scalp, moderate heat and regular trims.
Trim on schedule: short hair every 4-6 weeks, long hair's ends every 8-12 weeks
Dandruff and itch: wash regularly; for heavy dandruff use an anti-dandruff shampoo as labelled, such as ketoconazole, and see a pharmacist if it isn't better in a month
Hair loss: shedding 50-100 hairs a day is normal; patchy loss, clear thinning or unusual shedding needs a dermatologist
Heat: use a heat protectant before blow-drying or straightening and keep the temperature moderate
Colour or perm after a cut: patch-test 48 hours before every dye; stop and see a doctor if it stings, itches or swells
A final thought: the haircut day is a personal belief that brings peace of mind; go whenever suits you. What really makes hair look good is a stylist who gets your style and a healthy scalp.
