Drinking energy drinks accelerates hair loss in men.
Medics have found that men who guzzle down fizzy and sports beverages are 30 per cent more likely to suffer from follicle problems.
In the journal Nutrients, boffins from Tsinghua University in Beijing found that those who drank more one than one sweetened drink per day were 42 per cent more likely to experience hair loss than those who did not touch the beverages.
It has been emphasised in the past that a healthy diet is key for men to keep their long locks flowing.
Dermatologist Dr. Sharon Wong told The Sun newspaper: "Hair follicle cells are the second fastest dividing cells in the body and require all the nutrients of a well-balanced healthy diet.
"This includes lean proteins, good carbohydrates and fats, vitamins and minerals, but there is no one superfood for hair.
"As hair is not an essential structure for survival, the body does not prioritise the use of nutrients for hair growth.
"Nutritional deficiencies and crash diets are a common cause of hair thinning and shedding."
