Haircut moon calendar

The tradition picks a haircut day by the Moon: the phase stands for how fast hair grows back, the sign for the character of the day. Moon positions here are computed with Swiss Ephemeris - same engine as our moon calendar; the rules are folklore, and we say so plainly.

Which days does the tradition pick for a haircut?

The core most schools share (details differ between schools):

  • Waxing Moon - a cut “for growth”: hair, by the folk rule, grows back faster.
  • Waning - the shape holds longer, growth is calmer.
  • New moon and full moon - the tradition skips cutting.
  • Leo and Virgo - the most favourable signs; Taurus, Capricorn, Libra - good ones.
  • Cancer and Pisces - the tradition advises against.

Where the custom comes from, and what it actually claims

The belief has no author and no date. It belongs to a large family of farming lore built on likeness: a waxing Moon adds light, so it was held to add everything else, and hair cut while it grows was expected to grow back faster. The zodiac layer came later, from astrology, and that is where versions diverge most - some lists favour Leo and Virgo, others add Aries, others drop Virgo altogether. There is no canonical version, so any site presenting one list as the correct one has simply picked a version. The mechanism usually offered is that the Moon pulls at moisture the way it pulls at the tide. That is where it stops holding together: tidal force scales with the size of the body, which is why an ocean responds to it and a strand of hair does not. What we do here is keep the two layers apart - the numbers are real, the rules are custom - and let you see both.

Honestly, about what these rules are

There is no research linking the Moon’s phase to hair growth - this is folklore, not dermatology. What is real here: the Moon’s position for every day (phase, sign, exact new and full moons) - the same Swiss Ephemeris calculation used across this section. We show both the data and the rules; the choice of day is yours. A haircut on an “unfavourable” day will not harm your hair.
