What is Lunar Hair Care?
For centuries, humans have followed the moon's cycles to determine when to plant and harvest crops; planting during a particular lunar cycle determines what the crop will yield, and often how much it will yield.
This same practice can be applied to your hair. It's called Lunar Hair Care.
The Lunar Chart displays the 5 optimal dates each month for cutting your hair based on your specific hair goal.
