The general term used for hair loss is Alopecia.
Alopecia can have an impact on confidence and self-esteem. It can have severe effects on quality of life and emotional health.
There are different types of alopecia. Listed below are the main types of hair loss:
Alopecia areata is understood to be an autoimmune condition which causes patchy hair loss. It can result in a single bald patch or extensive patchy hair loss.
Alopecia totalis is a more advanced form of alopecia areata which results in total loss of all hair on the scalp.
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.
Alopecia barbae is alopecia areata that is localised to the beard area. It can be a single bald patch or more extensive hair loss across the whole of the beard area.
Also known as male pattern baldness or female pattern baldness. It is a thinning of the hair to an almost transparent state, in both men or women. It is thought to be a hereditary form of hair loss and is the most common type of progressive hair loss.
Scarring alopecias, also known as cicatricial alopecias, refers to a group of rare disorders which cause permanent hair loss.
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.
