Common Hair Diseases

Alopecia

Alopecia areata ("baldness in spots") is a form of hair loss from areas of the body, usually from the scalp. Because it causes bald spots on the head especially in the first stages, it is also called spot baldness. Hair loss can extend to eyebrows, eyelashes and facial and nasal hair and create more bald spots elsewhere in the body. (Source http://en.wikipedia.org/wiki/Alopecia_areata)

Signs:

Broken hairs, or hairs easily removed
Female diffuse baldness. A gradual thinning of hair, especially on the top of the head. Hairline generally remains intact.
One or more round or oval bald patches
What are the main causes

Androgenetic alopecia is caused by a genetic tendency for certain hair follicles to produce a substance that reacts with male hormones. As you get older, this reaction eventually causes the follicle to shut down.
Pulling from curlers or hairstyles that are too tight
A hereditary form of hair loss in which women progressively thin at the top of the head
Temporary hair loss may result from any shock to the body's systems, including starvation, systemic infection, childbirth, thyroid or immunologic disorders, drugs (especially chemotherapy for cancer), or stress.
Treatments:

Topical medication such as minoxidil lotion,
Alopecia areata— Cortisone injections
Hair transplants are a feasible option.

Hair Loss

Baldness , includes a set of disorders which involve the state of lacking hair where it would normally grow, especially on the head. The most common form of baldness is a progressive hair thinning condition called androgenic alopecia or 'male pattern baldness' that occurs in adult human males and some primate species. The severity and nature of baldness can vary greatly; it ranges from male and female pattern alopecia (androgenetic alopecia, also called androgenic alopecia or alopecia androgenetica), alopecia areata, which involves the loss of some of the hair from the head, and alopecia totalis, which involves the loss of all head hair, to the most extreme form, alopecia universalis, which involves the loss of all hair from the head and the body. Treatment for alopecia has limited success. The more hair lost, the less successful the treatment will be. (Source: http://en.wikipedia.org/wiki/Baldness).

Trichotillomania

Trichotillomania (TTM) or "trich" is an impulse control disorder characterised by the repeated urge to pull out scalp hair, eyelashes, beard hair, nose hair, pubic hair, eyebrows or other body hair. It may be distantly related to obsessive-compulsive disorder, with which it shares both similarities and differences. Trichotillomania has been mentioned as a disorder in very early historical records. Onset generally occurs at puberty. There is a strong stress-related component, that is, in low-stress environments some stop pulling altogether. Pulling resumes when one leaves this environment. 80% of those afflicted are female. Evidence is now starting to accumulate pointing to TTM as being genetic in origin. ( Source http://en.wikipedia.org/wiki/Trichotillomania).

Signs:

A behavioural problem or a bad habit that is often done unconsciously.
P laying with your hair by pulling on it or twisting it.
Feeling of pleasure or gratification, immediately following hair-pulling
Possible Causes:

There are many theories Psychoanalytic and Biological, but neither draws a concrete solution to its cause. For example, hair-pulling may begin as a response to stress and then develop into a habit.

Treatments:

Psychoanalysis focuses on childhood experiences
Medications such as antidepressants with serotonergic properties
Hypnotherapy
