How to choose a day for thicker hair with the moon phases.

Plenty of recommendations are available for the goal of thicker hair using a lunar hair care planning system. It’s easy. The challenging part is to match the right day with your salon and schedule. Astrologers and hair experts who champion the moon phases for hair treatments agree that the Full Moon is the best moon phase to cut hair to grow thicker.

The Moon Phase

The Full Moon is the most well-known moon phase. In the context of astrology, the Full Moon is all about completion, maturity and fulfillment. Whatever has been moving along for the last cycle reaches a peak of growth. In gardening, vegetables that grow annually above ground like beans and squash are planted to allow the seeds to absorb the most water. Leafy vegetables are harvested when the moon approaches full to capture the best flavor and nutrients.

The Moon Signs

Some folks take it even further by choosing particular astrological signs to lend a helping hand to the Full Moon phase. After researching more than thirty sources on the topic, it turns out that half of the zodiac contributes desirable qualities to growing hair thicker including Taurus and Cancer, Leo and Scorpio, Capricorn and Pisces. Their value favors the attributes of earth and water, fertile and semi-fertile, fixed and cardinal signs. Leo is the one exception to the absence of a dry/barren attribute, which is the most highly preferred astrological sign to cut hair to grow thicker at any time during the moon cycle.

Pick the Right Day

Several choices emerge to choose a day to cut hair to grow thicker. First is the day of the Full Moon. Even better is to add a recommended astrological sign that occurs on Full Moon day like Taurus. A third choice is the astrological sign that occurs within two days either side of a Full Moon. The final choice would be during any day that has the moon in one of the recommended signs.

Does cutting hair with the moon phase offer a guaranteed overnight success? Not at all. Working with natural cycles requires commitment: it may take a couple of months or a full year to see results. For some, an improvement may be noticeable within a few short weeks.

Lunar Hair FAQ: How do you calculate the dates for hair care?

The dates for lunar hair treatments in the Moon Hair Calendar are based on either:

An astrological sign
A moon phase, or
Both an astrological sign and a moon phase.


If the recommendation for a particular hair care treatment was not clear, I applied my knowledge of the moon phases to sort it out. For instance, my experience has shown that the Full Moon’s influence extends a good two days before and after.


Simple goals for hair care based on the moon phases and astrological signs become complicated very quickly. For instance, let’s take “cut hair to grow faster.” The New Moon is recommended and also the waxing moon – that’s the phase requirement; then there are recommended astrological signs.

So, the question becomes, what about the New Moon in a sign that is not recommended? For instance, take the case of a day for the New Moon but “cutting hair to grow faster” is not advised for a Virgo moon.


#1 MOON PHASE. Choose any New Moon as a day to “cut hair to grow faster” according to what a half dozen sources recommend consistently.

#2 ASTROLOGICAL SIGN. Then I mark it “BEST” when the New Moon occurs at the same time as the most recommended signs of Taurus, Scorpio and Capricorn.

Some veteran astrologers may say, “Oh, yeah–of course,” to that, but it was not clear to me until I got deep into the data.

Yes, this information can be confusing at best. I made the Moon Hair Calendar as an easy reference guide if you decide you want to try hair care with the moon phases.
