Lunar Hair Calendar December 2026: Best Days to Cut Your Hair Through Sagittarius and Capricorn

The lunar hair calendar for December 2026 has a problem in it, and it is worth knowing about before you book anything. The two signs the tradition prizes most for hair, Leo and Virgo, both fall in the waning half of the month. There is no waxing Leo or Virgo moon in December at all.

So for once you cannot have the phase and the sign agree. You choose. Below is every moon phase with its exact time, the moon sign for each day, and a straight answer about which days to take. All times are UTC, and Bali runs eight hours ahead. For the reasoning underneath the dates, when to cut hair for growth covers it properly.

The Lunar Hair Calendar December 2026 at a Glance

Five principal phases touch the month, one more than most. A last quarter moon opens it on Tuesday 1 December at 06:08 UTC with the moon in Virgo, just under half lit. The new moon arrives Wednesday 9 December at 00:51 UTC in Sagittarius. First quarter is Thursday 17 December at 05:42 UTC in Pisces. The full moon, the Cold Moon, peaks Thursday 24 December at 01:28 UTC at roughly one degree of Cancer, having entered the sign three hours earlier. A second last quarter closes the sequence on Wednesday 30 December at 18:59 UTC in Libra.

That gives a waxing half running 9 to 24 December and a waning half split across 1 to 9 and 24 to 31 December. The Sun sits in Sagittarius until Monday 21 December at 20:49 UTC, the solstice, then moves into Capricorn. The November 2026 lunar hair calendar runs in the same format.

Best Days to Cut Your Hair for Growth and Length

The waxing moon is the traditional window for length. Hair cut while the light increases is said to grow back faster and fuller at the ends, and the moon sign refines the texture of that regrowth.

20 and 21 December, moon in Taurus, eighty two rising to ninety percent lit. The two best days of the month, and it is not close. Taurus rules the throat and is the traditional sign of shine and density, and here it lands in a strong waxing gibbous moon. The 21st is also the solstice, with the moon leaving Taurus at 22:27 UTC that night. If you make one appointment in December, make it here.

18 and 19 December, moon in Aries, sixty three rising to seventy three percent lit. The pure speed days. Aries is associated with fast regrowth that comes back coarser, which suits thick or curly hair and frustrates fine hair.

15 and 16 December, moon in Pisces, thirty three rising to forty three percent lit. Pisces grows quickly and softly. Good for length, poor for structure, which suits anyone growing hair out who only needs the ends taken off.

Best Days to Cut for Thickness and Strength

The waning moon slows regrowth, which sounds like a disadvantage and is not. A waning cut holds its shape longer, which is what you want from a fringe, a bob, or any line you have paid to have precisely placed. It is also the traditional choice for thickening at the root.

26 and 27 December, moon in Leo, ninety one falling to eighty three percent lit. Leo governs the hair itself in traditional correspondence, and a waning Leo moon is the classic combination for density at the scalp. This is the only Leo window in the month, and it sits in the quiet week between Christmas and the new year, which makes it unusually easy to book.

28 and 29 December, moon in Virgo, seventy four falling to sixty four percent lit. Virgo is precision. The window for removing split ends without losing length. The same combination appears on 1 and 2 December with less light behind it, if you cannot wait four weeks.

The Days to Skip in December 2026

Skip 8 and 9 December. The moon is dark, under half a percent lit, and the tradition is consistent across cultures that this is the lowest point of vitality in the cycle. Nothing terrible happens if you cut then. The rest of the month is better.

Treat 24 December, the exact full moon, with care. Many lunar hair traditions consider the full moon excellent for oiling but volatile for cutting, and this one falls in Cancer, a water sign associated with softness rather than hold. Use it for a rosemary oil ritual and take your cut on the 20th. Be cautious too around 13 and 14 December in Aquarius, and 22 and 23 in Gemini. Both air signs, both linked to frizz.

What the Solstice Does to the Month

Sagittarius season runs until the 21st and it is the least patient season of the year. It is also the one in which most people are travelling, hosting, or standing in a kitchen they do not live in, which is precisely when the urge to cut your own fringe arrives. The solstice is the turn. Capricorn season asks what you are actually building, and the best cutting days of the month sit right on that hinge.

Common Questions About the Lunar Hair Calendar December 2026

What are the best days to cut hair for growth in December 2026? The 20th and 21st of December 2026 are the strongest days, because the moon is waxing gibbous at eighty two to ninety percent lit and passing through Taurus, the sign traditionally linked to shine and thickness. The 18th and 19th, moon in Aries, are next best for pure length.

When is the full moon in December 2026? The full moon in December 2026 falls on Thursday 24 December at 01:28 UTC, at roughly one degree of Cancer. It is commonly called the Cold Moon, and it is the last full moon of the year.

Is it bad to cut your hair on a new moon? Traditional lunar hair practice avoids the new moon, which in December 2026 is the 9th, because the cycle is at its lowest point of light and regrowth is considered slowest. There is no evidence of harm. It is simply the least favourable timing in a month with better options.

Why are there no good Leo days for growth in December 2026? Because the moon only reaches Leo on 25 December, the day after the full moon, so the entire Leo window falls in the waning half. Waning Leo serves thickness and density rather than length. For growth you take Taurus on the 20th and 21st instead.

What is the difference between cutting on a waxing and a waning moon? Cut on a waxing moon for faster, fuller regrowth and added length. Cut on a waning moon for slower regrowth, a shape that holds longer, and more density at the root. Waxing serves length. Waning serves structure.

For the whole year rather than one month, the 2026 lunar hair calendar hub maps every cycle, and the feng shui haircut calendar runs the same question through the Chinese almanac, which reaches different answers worth knowing about.

December asks you to choose between the phase and the sign. Which is really the year asking whether you want length, or you want it to hold.
