New Delhi, Dec. 11 -- With your first grey strand comes ageing, but it could also be a sign of too much stress, say experts.

"Premature greying can be a sign of excessive stress as it is one of the significant causes; under pressure, one constricts the blood vessels hampering the healthy flow of nutrients to the scalp resulting in hair fall and greying.

"Stress also reduces oxygen supply to the scalp as breathing, and is also one of the major causes of aging and premature greying, dull, and scanty hair," Rajni Ohri, Founder, Ohria Ayurveda said.

Although ageing is natural, and should be accepted with grace, one cannot control the process of ageing and worrying about it will only further stress.
