The word Alopecia is the medical phrase for loss of hair and can apply to small areas or complete baldness. Alopecia can occur in a variety of forms. We all know that some medical treatments can lead to hair loss. Chemotherapy, for example, involves elements that are "cell toxic", necessary in order to attack cancer cells effectively. Not all chemotherapy drugs cause hair to thin, while others do produce complete loss. Hair loss can happen suddenly, although it is usually more gradual and begins within two or three weeks of starting treatment.
AREATA
Small bald circles resulting from different causes.
TOTALIS
An extension of areata leading to complete hair loss on the head. The condition is one of the most dramatic and potentially distressing types of baldness. All hair follicles have entered a "dormant" phase and this can sometimes affect eyelashes and eyebrows as well.
UNIVERSALIS
The loss of all body hair as a result of either physical or medical causes.
POST PARTUM
At any time in the first four months after giving birth, some women may experience loss of hair. Usually this will occur in two stages: alopecia areata - small round patches can appear anywhere; then diffuse - with the scalp losing up to 50% of its hair giving a wispy appearance.
TELEGEN EFFLUVIUM AND DIFFUSE ALOPECIA
These refer to the same condition, a percentage loss all over the scalp, causing the hair to look sparse and wispy. There can be a reduction of up to 60%, usually caused by the hair growth mechanism being "switched off" and the hair falls out without reaching the end of the normal life span. This condition and its causes are not well understood. It can follow emotional distress or trauma and may not appear to up to six months after the event. Recovery occurs in some cases
FEMALE PATTERN BALDNESS
This is the inherited (genetic) loss of hair in women but unlike men, women do not lose hair in specific patterns on the top of their heads. Instead hair thins to a degree that is noticeable. Usually there are hormone changes involved at the onset of menopause when the levels of testosterone rise against those of "female" hormone oestrogen.
CIRATRICIAL ALOPECIA
This is the scarring of the scalp from a number of possible causes including medical or physical. The term applies to permanent hair loss as a result of the destruction of the hair follicles.
TRICHATILOMANIA
Self inflicted loss is caused by compulsive tweaking and pulling hair. This may result in minor or extensive bald patches. There are increasing incidences of the condition and it is considered a sign of stress and in some cases self dislike. A wig or hairpiece can be used to disguise the damage and also to help the recovery of hair. Counselling and professional support is advisable.
