Hair loss is becoming prevalent amongst younger age groups, according to experts.
Male pattern baldness used to be associated with middle age, but Christopher Wainwright, an Australia-based hair expert with the
Svenson Hair Centre, says this is starting to change: "Hair loss has usually been found among men aged 30 to 40, but now men 20 to 30 are becoming the majority facing the problem."
Wainwright, speaking on tour in Bangkok, said that lifestyle was likely to be the reason for the shift: "Asian or Western, men have a similar hair-loss problem. There is no difference in the pattern. The only difference is that Asian men have hair shafts that are a little bit thicker - actually they've got better hair.

"But in recent years I've found that lifestyle is becoming more and more influential in hair loss. Eating habits, stress from work, high-sugar diets, etc."
Wainwright went on to say that excessive hair loss can result from many factors, including illness, and major surgery, though these involve stress and the hair loss is often temporary. Hormonal imbalance is another potential cause of hair loss, both for males and females.
Hair grows in cycles, usually between two and six years. Male pattern baldness tends to start revealing itself above the forehead, then at the crown. The progression of hair loss in men is related to the sweat glands that exude dihydrotestosterone (DHT) in these areas.
