What to do when
Under a waxing Moon — tradition says hair regrows faster after a cut.
Under a waning Moon — the cut lasts longer and regrowth slows.
The favourable signs (Leo, Virgo, Taurus, Capricorn, Libra) are also the traditional colouring days.
Under a waning Moon — the traditional time for masks, nourishing and root care.

How does a lunar haircut calendar work?
Two rules combine. Under a waxing Moon (new → full) tradition cuts for faster regrowth; under a waning Moon, to keep the shape and strengthen the roots. The zodiac sign sets the verdict: Leo and Virgo are best, Taurus, Capricorn and Libra favourable, Cancer and Pisces unfavourable, the rest neutral. The new and full moon are rest days.
Is there scientific evidence?
No. The moon phase and its zodiac sign are astronomically computed and verifiable, but their link to hair growth is folk belief. This page reproduces the rules of the popular lunar almanacs as entertainment — it is not advice.
