The most fundamental cause of hair loss is inadequate iiultltion. Persons lacking in vitamin B6 lose their hair and
those lacking in folic acid often become completely bald. But the hair grows usually after the liberal intake of these vitamins.
Stress, Prolonged Illness, impure conditions — Other important causes of hair loss are stress such as worry, anxiety, and unexpected shock, general body debility caused by severe or long standing illnesses like typhoid, syphilis, chronic cold, influenza, and anaemia an unclean situation of the scalp that weakens the hair roots by jamming the pores with the collected dirt; and heredity
There are several other kinds of baldness: Traction alopecia is most commonly found in people with ponytails or corn rows who pull on their hair with excessive force. Trichotillomania is the loss of hair caused by compulsive pulling and bending of the hairs. It tends to occur more in children than in adults. In this condition the hairs are not absent from the scalp but are broken. Where they break near the scalp they cause typical, short, exclamation mark hairs.
Traumas such as chemotherapy, childbirth, major surgery, poisoning, and severe stress may cause a hair loss condition known as telogen effluvium.
Worrisome hair loss often follows childbirth without causing actual baldness. In this situation, the hair is actually thicker during pregnancy due to increased circulating oestrogens. After the baby is born, the oestrogen levels fall back to normal pre-pregnancy levels and the additional hair foliage drops out. A similar situation occurs in women taking the fertility-stimulating drug clomiphene.
Iron deficiency is a common cause of thinning of the hair, though frank baldness is not usually seen.
Radiation to the scalp, as happens when radiotherapy is applied to the head for the treatment of certain cancers there, can cause baldness of the irradiated areas.
Some mycotic infections can cause massive hair loss. Alopecia areata is an autoimmune disorder also known as spot baldness that can result in hair loss ranging from just one location {Alopecia areata monolocularis) to every hair on the entire body (Alopecia areata universalis).
Localized or diffuse hair loss may also occur in cicatricial alopecia (lupus erythematosus, lichen piano pilaris, folliculitis decalvans, central centrifugal cicatricial alopecia, post-menopausal frontal fibrosing alopecia, etc.). Tumours and skin outgrowths also induce localized baldness (sebaceous nevus, basal cell carcinoma, squamous cell carcinoma).
Hypothyroidism can cause hair loss, typically frontal, and is particularly associated with thinning of the outer third of the eyebrows (syphilis also can cause loss of the outer third of the eyebrows) Hyperthyroidism can also cause hair loss, which is parietal rather than frontal. Temporary loss of hair can occur in areas where sebaceous cysts are present for considerable duration; normally one to several weeks in length.
