Alopecia sufferer claims £12.95 shampoo helped her regain hair

Alopecia, which causes baldness, is thought to be an auto-immune disorder, with the immune system -the body’s defence system – turning on itself. 

What are the symptoms?

‘Typically, one or more small bald patches, about the size of a 50p piece, appear on the scalp. The hair can start to regrow at one site, while another bald patch develops. Hair may also begin to thin all over the head,’ says Marilyn Sherlock, chairman of the Institute of Trichologists. 

What causes it?

‘For some reason, the body’s immune system begins to attack its own hair follicles. Special white blood cells in the body, known as T-lymphocytes, cause the hair to stop growing,’ she adds.

Can worry make it worse?

Stress has been shown to prolong the problem.

Are there other symptoms apart from baldness?

‘Occassionally, the scalp may become sore or sensitive.

‘Some people complain that it feels as if their scalp is bruised,’ says Mrs Sherlock. 

Is it an inherited condition?

There is strong evidence to suggest that alopecia, like other auto-immune diseases, runs in families. About 25 per cent of patients have a family history of the disorder. 

Who gets it?

Alopecia areata usually affects teenagers and young adults, but it can affect people of any age. It is just as common among men as women. 

Is there a cure?

There is no known cure, although there are various treatments which may be effective for some people.
