Common causes of hair loss

Descriptions of the main reasons for hair loss are available on our other web-pages, baldnessalopecia and smp for women where photographs are also available. The conditions summarised below are some of the most common.

Specific alopecia advice and support is available from Alopecia UK online. The organisation also has a number of voluntary local support groups.

Androgenic Alopecia (AGA)

It is thought to be hereditary form of and is the most common type of progressive hair loss, one that affects both men and women. It happens because of a hormone known as dihydrotestosterone (DHT). This hormone attacks the hair follicles and causes permanent hair loss or a thinning to such an extent that the hair is virtually transparent.

Alopecia Areata (AA)

A disease also known as the bald spot condition. Alopecia Areata is an autoimmune disease that makes your own body attack the hair follicles. The causes have yet to be discovered, but doctors know that this condition usually treats itself without any drugs. Despite this some GPs will prescribe steroid injections for repeated cases. It can result in a single bald patch or extensive patchy hair loss. Jon was treated by us after suffering AA and his story can be found on our YouTube channel.

Alopecia Totalis (AT)

Alopecia totalis is a more advanced form of alopecia areata which results in total loss of all hair on the scalp.

Alopecia Universalis (AU)

Alopecia universalis is the most advanced form of alopecia areata which results in total loss of all hair on the body, including eyelashes and eyebrows.

Traction Alopecia

Traction alopecia is usually due to excessive pulling or tension on hair shafts as a result of certain hair styles. It is seen more often in women, particularly those of East Indian and Afro-Caribbean origin. Hair loss depends on the way the hair is being pulled. Prolonged traction alopecia can stop new hair follicles developing and lead to permanent hair loss. It’s a common condition in Sikhs who wear a turban, for instance.

Scarring Alopecias (Cicatricial Alopecias)

Scarring alopecias, also known as cicatricial alopecias, refers to a group of rare disorders which cause permanent hair loss.

Telogen Effluvium

This disease is also known as diffuse hair loss and it causes a lot of hair to fall in a short period of time. Telogen Effluvium can be caused by a lot of factors, such as pregnancy, chemotherapy, a very high fever, severe illnesses or high levels of stress. Despite the look of it, it’s not a permanent condition and most of the lost hair grows back in a few months after the first symptoms. Scalp Micro Pigmentation is particularly useful in these cases as it does not inhibit hair re-growth.

Anagen Effluvium

This hair loss is generally caused by chemicals, such as those used to treat cancer. Initially it causes patchy hair loss, which often becomes total hair loss. The good news is that when you stop using these chemicals the hair normally grows back (usually about 6 months later). Other drugs also can cause hair loss. Many medicines used to treat even common diseases can cause hair loss as a side-effect.

Other causes

Aside from these conditions, other common causes of hair loss are a poor diet, excessive stress, an injury or certain skin diseases. These types of hair loss can also be permanent.

Scalp Micro Pigmentation offers an effective solution to all the above conditions, call us to arrange a no-obligation consultation.
