Why the favoured sign is dark in August
The rule generalises to every sign. Whatever sign the Sun occupies, the Moon crossing that sign is new, and the sign opposite carries the full moon instead. Since the Sun works through the zodiac once a year, each sign takes a turn at being dark and, six months later, a turn at being lit. Leo's dark turn is August, which is why this calendar opens with a new moon in Leo on the 12th and pushes the run into Virgo on the 13th to the 15th. Six months on, in February 2027, those same two signs will be carrying a full moon.

This is folklore, not dermatology: the Moon’s position on this page is computed with Swiss Ephemeris, no research links the phase to hair growth, and a haircut on an “unfavourable” day harms nothing. How the rules work.
