Lunar haircut calendar, March 2027: best days to cut hair by the moon

What is a lunar haircut calendar?

A lunar haircut calendar is a folk calendar that ties the day of a haircut to the phase of the Moon. Its main rule is simple: hair cut while the Moon is waxing is said to grow back faster, and hair cut while the Moon is waning is said to grow back more slowly and hold its shape longer. The day of the new moon and the lunar days 9, 15, 23 and 29 are traditionally avoided. It is a tradition, not a finding of science: there is no evidence that hair grows at a different rate depending on the Moon.

Waxing or waning moon: when to cut hair

The rule behind every lunar haircut calendar is the direction of the Moon. From the new moon to the full moon the Moon is waxing, and folk tradition says that hair cut in these two weeks grows back faster, so this is the time chosen by people who are growing their hair out. From the full moon to the next new moon the Moon is waning: a cut is said to grow back more slowly and keep its shape longer, which suits short, precise haircuts and fringes.

Haircut on a new moon and on a full moon

The day of the new moon is the one day almost every folk calendar agrees on: no haircut. In March 2027 the new moon falls on 8 March. About the full moon tradition is divided. Some calendars recommend a cut on that day for thickness, others advise waiting a day, so this calendar marks the full moon day (22 March) as neutral unless it falls on a difficult lunar day.

Lunar days 9, 15, 23 and 29: the days tradition avoids

Folk lunar calendars count the days of the lunar month from the new moon and call the 9th, 15th, 23rd and 29th difficult. Haircuts, colouring and other changes are traditionally not planned for them. In March 2027 these lunar days fall on 1, 7, 16, 22 and 31 March.

Hair colouring by the lunar calendar in March 2027

For colouring the tradition follows the same direction as for haircuts. A waxing moon is chosen for a new colour or a refresh, because the colour is said to hold longer; on a waning moon colour is said to fade sooner, so those days are left for small corrections. Favourable days for hair colouring in March 2027: 9–15 and 17–21 March.

Manicure and hair removal by the lunar calendar in March 2027

For nails and hair removal the tradition turns around: what should grow back slowly is done on a waning moon. A manicure or pedicure is said to stay neat longer, and removed hair is said to return more slowly. Favourable days for a manicure and hair removal in March 2027: 2–6 and 23–30 March.

Does the moon affect hair growth? What science says

Hair on the scalp grows about 1 cm a month, roughly 15 cm (6 inches) a year. The rate depends on age, genetics, hormones, nutrition and health. There is no scientific evidence that it depends on the phase of the Moon, and cutting hair does not change how fast it grows at the root. What a calendar like this does give is a rhythm: a regular reason to book a trim.
