Getting your haircut on a favourable day will make it healthier, accelerate its growth and won't affect the energy flow in the body. On a neutral day, energies are balanced and do not have either a positive or negative effect. Getting your hair trimmed on an unfavorable day can slow down hair growth and have a negative effect on hair's condition.
Key Recommendations:
If you are to cut your hair during the growing Moon, it will grow faster
Haircut during the Waning Moon will slow down hair growth but will strengthen the roots and reduce hair loss
You shouldn't cut your hair straight after having a meal
