Fawlty Towers star John Cleese has admitted to Richard and Judy that he has had a hair transplant.
Cleese said he'd opted for the procedure "because I've got a very strange shaped skull, very pointy and I don't like wearing wigs."
Treatments for male pattern baldness have improved a lot since the days of Hippocrates (he applied a mixture of pigeon droppings, horse-radish, cumin and beetroot to his head).
Today there are medicines that have been proven in some cases to encourage new hair growth and stop the rate of hair loss; and there are human trials currently taking place to see if hair follicle cells grown in the lab will grow in the head once replanted.
To follow in Cleese's footsteps and have a hair transplant costs between £5,000 and £8,000.
Male pattern baldness is the most common form of hair loss in men. It usually develops slowly, and starts with the appearance of a bald spot on the crown of the scalp accompanied by thinning at the temples. Male pattern baldness is also known as genetic hair loss or alopecia androgenetica, and will affect half of all British men by the time they are 50.
