Waning Moon in Taurus, Libra, Scorpio, Aquarius
Principles of western astrology for lunar hair care hold that hair appears to grow back more slowly during the waning moon. That is the time between the Full Moon and the New Moon.
The waning moon starts the day after the Full Moon. The strength of the “slower” effect grows more each day for the rest of the phase. A BEST rating starts three days after the Full Moon. The BEST+ rating starts two days after the Last Quarter moon and continues to one day before the New Moon.
The recommended signs are the same for “Color hair” – Taurus, Scorpio, and Aquarius – with the addition of Libra with the waning moon.
