According to Ayurveda due to night shift your pitta is increasing which is one of the cause for greying of hair.their might be other causes also for that I need detail history with which I can help you.

This is happening due to increased conversion of testosterone to DHT and reduced nutrition to scalp and hair follicles. Thus, hair become weak from their roots(follicles) and acclerate hair fall. The good news is that this is easily treatable with ayurvedic tablets. These tablets block conversion of testosterone to DHT. At the same time, these tablets nourish hair follicles making hair strong and prevent hair fall. Please let me know if you have any other disease or abnormal symptoms. Otherwise, this is easily managed with our wedel capsules. Regards Dr. Omkar Balkrishna Shahapurkar Pune
