Hair colouring calendar by year
Frequently asked questions
Is today a good day to dye my hair?
Today the Moon is waning and sits in Gemini (mixed folk readings — no clear call). Verdict by tradition: neutral day.
Which are the best days to dye hair in October 2026?
In October 2026 the good colouring days are 5, 6, 7, 8, 9, 11, 17, 18 and 27, the best being 7, 8, 9, 11 and 27 (Moon in Taurus, Virgo or Libra).
How does a lunar hair colour calendar work?
The zodiac sign holding the Moon sets the verdict: Taurus, Virgo and Libra are the best colouring signs, Leo and Capricorn good, and Cancer, Pisces and Scorpio (the water signs) unfavourable. The phase says what the day suits: a waxing Moon for a new colour (richer and longer-lasting), a waning Moon for roots and refreshing, since hair grows more slowly. No colouring on new-moon and full-moon days.
When should I dye my hair so the colour lasts?
By tradition — under a waxing Moon for a new colour and a waning Moon for roots, on a day with the Moon in Taurus, Virgo or Libra. The calendar lists the exact days for every month.
When is a good day for a perm?
The popular lunar almanacs recommend perms with the Moon in Virgo or Libra; with the Moon in Leo the curls come out tighter. No perms on new-moon or full-moon days.
Is it the same as the haircut calendar?
Both calendars use the same favourable colouring signs, so they never contradict each other. The colouring calendar adds when a day suits a new colour versus roots, plus the perm and sensitive-scalp days.
Is there scientific evidence?
No. The moon phase and its zodiac sign are computed astronomically and are verifiable, but their link to hair colour is folk belief. The calendar is entertainment and curiosity, not advice.
