Frequently asked questions

How many good hair-colouring days are there in 2040?

2040 has 150 good days to dye your hair by folk tradition, 91 of them excellent — with the Moon in Taurus, Virgo or Libra.

Which moon signs are best for colouring?

Taurus (lasting and gentle), Virgo (even coverage) and Libra (changing shade) are the best; Leo and Capricorn are good; Cancer, Pisces and Scorpio unfavourable. No colouring on new-moon and full-moon days.

New colour or roots?

By tradition a new colour goes on under a waxing Moon, when it is richer and lasts longer, and roots or a refresh under a waning Moon, when hair grows more slowly.

The moon phase and its zodiac sign are computed astronomically (tropical zodiac). The colouring rules are folk tradition from the popular lunar almanacs — reproduced for entertainment and curiosity; they are not advice and have no scientific confirmation.
