Hair Loss- Types
Androgenetic Alopecia Male-pattern hair loss,
also known as androgenic alopecia and male
pattern baldness (MPB), is hair loss that occurs
due to an underlying susceptibility of hair
follicles to androgenic miniaturization. It is
the most common cause of hair loss and will
affect up to 70 of men and 40 of women at some
point in their lifetimes Alopecia Areata Also
known as spot baldness, is an autoimmune disease
in which hair is lost from some or all areas of
the body, usually from the scalp due to the
body's failure to recognize its own body cells
and destroys its own tissue as if it were an
invader. In 12 of cases, the condition can
spread to the entire scalp (alopecia totalis) or
to the entire epidermis (alopecia
universalis). Alopecia Totalis (AT)-Total loss
of the hair on the scalp. Alopecia totalis is the
loss of all head hair. Its causes are unclear,
but believed to be autoimmune. Stress is thought
to be a contributor. However, many with the
disorder lead relatively low stress
lives. Alopecia Mucinosa (also known as
"Follicular mucinosis," "Mucinosis
follicularis,", "Pinkus follicular mucinosis,"
and "Pinkus follicular mucinosisbenign primary
form") is a skin disorder that generally
presents, but not exclusively, as erythematous
plaques or flat patches without hair primarily on
the scalp and face. This can also present on the
body as a follicular mucinosis and may represent
a systemic disease.

Hair Loss- Types
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 is very common. In india it is common
in Sikhs. Anagen Effluvium--This hair loss is
generally caused by chemicals such as those used
to treat cancer. It is the pathologic loss of
anagen or growth-phase hairs. Classically, it is
caused by radiation therapy to the head and
systemic chemotherapy, especially with alkylating
agents Scarring Alopecia Cicatricial alopecia,
also known as scarring alopecia, is a diverse
group of rare disorders that destroy the hair
follicle, replace it with scar tissue, and cause
permanent hair loss. A variety of distributions
are possible. In some cases, hair loss is
gradual, without symptoms, and is unnoticed for
long periods. Telogen Effluvium is a scalp
disorder characterized by the thinning or
shedding of hair resulting from the early entry
of hair in the telogen phase (the resting phase
of the hair follicle)

Male Pattern Baldness
Male pattern hair loss is an inherited condition,
caused by a genetically determined sensitivity to
the effects of dihydrotestosterone, or DHT in
some areas of the scalp. DHT is believed to
shorten the growth, or anagen, phase of the hair
cycle, from a usual duration of 3-6 years to just
weeks or months. This causes miniaturization of
the follicles, and producing progressively fewer
and finer anagen hairs. The production of DHT is
regulated by an enzyme called 5-alpha
reductase. Several genes are involved,
accounting for differing age of onset,
progression, pattern and severity of hair loss in
family members. The susceptibility genes are
inherited from both mother and father. At this
time, genetic testing for prediction of balding
is unreliable.

Female Pattern Baldness

• The reason for female pattern baldness is not
  well understood, but it may be related to
• Aging
• Hormonal changes (Menopause changes)
• Family history of male or female pattern baldness
• Breaking of hair (from treatments and twisting or
  pulling of hair)
• Certain skin diseases that lead to scarring of
  the hair follicles
• Other related reasons
• Certain autoimmune diseases-e.g. Lupus
• Hormone problems, such as too much testosterone,
  or too much or too little thyroid hormone
• Too little iron
• Too little vitamin B (biotin) or other vitamin
  deficiency
• Medications such as chemotherapy and beta
  blockers
• Patchy hair loss
• Syphilis, a sexually transmitted infection
• Temporary shedding of hair after a major illness,
  surgery, or pregnancy
