If you’re thinking of getting a haircut, freshening up your style, or simply trimming your ends, astrology says timing matters. According to lunar experts, the Moon's phases can influence hair health and growth—choosing the right day could result in stronger, thicker, shinier hair, while the wrong day may lead to damage or slower growth.
