Non-Scarring Alopecias


Alopecia areata (patient advocates ) This is a moderately easy to diagnose with generally a good prognosis except in marginal ophiasis (poor). It can be treated by a variety of methods. Intracutaneous injection of dilute suspensions of Kenalog is the method of choice. This can be done with ethyl chloride (Fluoroethyl) spray prior to the quick insertion of 1 cc/sq. in. (50-50 dilution with water). Repeat it monthly for 3 months, and if this does not grow hair, then switch to daily application of anthralin or contact sensitization with dibutyl squaric acid 1% solution. Many patients give a family history. Occasional cases progress to alopecia totalis or universalis .


Androgenic Alopecia. -- Diffuse hair loss is a very common and insidious thinning of the vertex and frontal scalp in young or middle-aged women who have both male and female relatives demonstrating partial baldness. There is often seborrhea. Preservation of the frontal hairline is much more common in women than in men. Topical minoxidil 2% solution applied twice daily may be of benefit.


Telogen effluvium:


Post-partum alopecia


Hypothyroidism


Iron deficiency


Chemotherapy

 


Hyperthyroidism


Scarring Alopecias


Follicular degeneration syndrome in black patients


Lichen Planopilaris


Folliculitis Decalvans (sycosis of the scalp). -- This condition sometimes responds to Betadine shampoo, systemic antibiotics over a long period of time, and locally applied antibiotic creams at night as well.


Perifolliculitis capitis abscedens et suffodiens. -- this is a tunneling pyoderma like hidradenitis suppurativa, and it responds to similar treatment.


Pseudopelade of Brocq. --


Loose anagen syndrome


Trichotillomania


Traction alopecia


Lupus erythematosus. -- Chronic cutaneous (discoid) lupus may respond to intralesional corticosteroids or antimalarials.


Fungal Kerion. -- the scarring induced by a kerion is often permanent.


Scleroderma. -- the striking form, coup de sabre, often induces follicular loss.


Nevus Sebaceous.-- this is a orange-yellow birthmark which becomes warty with puberty and often degenerates to carcinomas of various types. Surgical removal is advised.


Trichothiodystrophy


Secondary syphilis


Alopecia Neoplastica


Hirsuitism

At puberty and menopause, was well as during pregnancy, there may be temporary spurts in hair growth, which often are self-correcting. There are certain families who are hirsute, and all their endocrine studies are normal. There are other cases of hirsutism, however, associated with acne, menstrual disorder, obesity and even, on occasion, hypertension, where an endocrine explanation has to be considered. Cushing's syndrome, adrenal virilism, polycystic ovary (Stein-Leventhal syndrome), ovarian tumors and basophilic adenoma of the pituitary are some of the entities producing hirsutism. Elevation of the entities producing hirsutism. Elevation of the urinary 17-ketosteroid level indicates that an endocrine testis needed. Treatment. -- Shaving with an electric razor is often suitable for elderly women with bristles. Depilatories, applied for a definite time and then washed off, destroy the hair chemically, though they can be irritating to the skin. Plucking is the usual method, although poor eyesight and inaccurate plucking may lead to inflamed papules and scarring. Electrolysis is tedious with the galvanic current, and the diathermy can leave pits. however, a skilled operator can achieve satisfactory results if the work is repeated carefully. Wax depilatories strip the hair off by pulling it out. Bleaching with peroxide and ammonia, equal parts, produces transparent bleached hair that sometimes is acceptable cosmetically.
