I am using Navratan hair oli from many years when I feel headache or stressed,
Navratan hair oil is the product of one the best company i.e. Himani,
It is a herbal product contain totally natural ingredients like Amla, pudia ka phool etc,
which is not harmful at all, this hair oil helps in hair growth too,
and one best quality is relief from headache.just simpel massage of navratan hair oil gives relief from headache and stress,
you will fill cool after massage with navratan oil, many peoples does not like smell of it but I advice you should massage with navratan hair oil in evening after stressful day it will help you a lot,
its simple to use also just take it on palm and genitally apply in hair.
my opinion would be that who have there days full of stress should try navaratan oil once,
and it is not costly you can get it at any nearby store.
