Hair growing in a dream usually reflects returning vitality -- energy, confidence, or self-expression coming back after a period where it felt diminished. Thick, fast-growing hair can point to a renewed sense of identity, a visible sign that something in you is regenerating rather than fading away.
The misfortunes proceeding from Saturn or Mars are mitigated, if their places are protected by Jupiter, being well disposed and in good aspect. - William Lilly (1602.-1681.)
