Vegan and vegetarian diets could accelerate hair loss in men, according to an expert, since meat contains vital iron that helps locks grow.
These diets have become increasingly popular in recent years, with the number who shun dairy, meat and other animal products rising by 360 per cent between 2006 and 2016.
A number of celebrity fans – such as Casey Affleck, Beyonce and Jared Leto – and health claims, including weight loss and longevity, have caused many to drastically alter their eating habits.
However, ditching meat could mean missing out on vital nutrients for hair growth.
Foods such as red meat, pork and poultry are rich in iron, and a deficiency in the mineral can speed up hair loss.
“Iron deficiency is a factor in hair loss since it’s necessary for hair growth.
“With a lot of people shunning meat – possibly due to vegan and vegetarian diets – it is possible people are missing out on the nutrient.
“It is possible to consume enough iron on such diets, but it’s more difficult and easy to not get enough.”
Other sources of iron include spinach, beans and dried fruit.
According to the NHS, it is recommended men get 8.7mg a day.
Dr Jones’s comments come as new research reveals the phycological impact of hair loss on young men.
It is estimated that around 50 per cent of men will lose some hair by the age of 50, with many suffering from an even earlier age.
Research carried out by Asda Pharmacy revealed that 38 per cent of those under 35 said their hair loss made them feel depressed.
Additionally, 26 per cent admitted it made them more prone to drinking and drug taking.
