Alopecia is a general term for hair loss. Alopecia areata is a common cause of non-scarring (does not cause scarring to the scalp) hair loss that can occur at any age. It usually causes small, coin-sized, round patches of baldness on the scalp, although hair elsewhere such as the beard, eyebrows, eyelashes, body and limbs can be affected. In some people larger areas are affected and occasionally it can involve the whole scalp (alopecia totalis) or even the entire body and scalp (alopecia universalis)..
Psoriasis is more than just a skin condition, and it can affect people physically and psychologically. Although there is no cure for psoriasis, it is important to remember that it can be managed. With the right treatment and advice, many people live well with psoriasis.
Seborrhoeic dermatitis is thought to affect up to five in every 100 people in the UK. However, there are many more people who have a mild form of the disease, without even being aware they have it. Dandruff is a mild form of seborrhoeic dermatitis that affects your scalp. You can develop seborrhoeic dermatitis at any age, from puberty onwards. It's most common to develop it between the ages of 30 and 70, although many people also get it as a teenager. It’s more common in men than women.
Dandruff is a skin condition that mainly affects the scalp. Symptoms include flaking and sometimes mild itchiness. It can result in social or self-esteem problems. A more severe form of the condition, which includes inflammation of the skin, is known as seborrhoeic dermatitis. The cause is unclear but believed to involve a number of genetic and environmental factors. The condition may worsen in the winter. It is not due to poor hygiene. The underlying mechanism involves the over growth of skin cells. Diagnosis is based on symptoms. There is no known cure. The typical treatment is with antifungal cream such as ketoconazole. Dandruff affects about half of adults. Onset is usually at puberty. Males are more often affected than females. Rates decrease after the age of 50.
Hair loss is relatively common in women, more common than one would imagine. Half of women over the age of 50, have some degree of cosmetic hair loss. The presentation, however, is much different than in men and the management of women with hair loss requires significant expertise in both diagnosis and treatment. For those women in whom surgical hair restoration is indicated, special surgical skills are required to achieve the best results. It is a mistake for a surgeon to assume that hair loss in women can be treated the same way as in men and hair transplants in over 90% of women is the wrong decision.
