I always use navaratna oil twice a week. If you feel headache. This is one of my favourite oil. It is really good for head massage. it’s a very good oil but it should not be use regularly if you use it every day it start hair loss because of menthol in the oil which makes cooling sensation it’s my personal experience with this oil. If someone have headache and he is looking forward to have medicine for instant relief in this situation Navaratan oil provide instant relief from the pain. Overall rating 3/5.
