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.
