Thank you for sharing your experience Ianthou!
I hear from Baba Ramdev that 30 min pranayam a day works magic in many ways, including grey hair and hair loss.
I have been losing some hair after my last fast, hoping it is a sign of renewal and an echo from the stress on the body. It is thick still, so I am not very worried.
I may try some of your suggestions, if pranayam does not work its wonders soon enough :) Added your message to my favorites :)
