Best Days to Dye Hair in August 2018
The best days to dye your hair in August 2018 are 4, 5, 10, 12, 13, 14, 15, 21, 22, 23 and 31, with 4, 5, 12, 13, 14, 15 and 31 the most favourable (Moon in Taurus, Virgo or Libra). Skip 8, 9, 11, 16, 17, 18, 26, 27 and 28 (New Moon — 11 August · Full Moon — 26 August). These readings follow lunar folk tradition — the Moon’s phase and zodiac sign.
What to do when
Waxing Moon in a favourable sign — tradition says the colour is richer and lasts longer.
Waning Moon in a favourable sign — hair grows more slowly, so roots show later.
Moon in Virgo or Libra; in Leo — tighter curls.
Moon in Taurus — by tradition the gentlest day if dye irritates your scalp.
