They may also occur on the face, usually on the eyelids. Though tags up to half an inch (12.7 mm) long have been seen, [ 2] they are typically the ...
The HAIR-AN syndrome is a rare subtype of polycystic ovary syndrome (PCOS) characterized by hyperandrogenism (HA), insulin resistance (IR) and acanthosis nigricans (AN). The symptoms of the HAIR-AN syndrome are largely due to severe insulin resistance, which can be secondary to blocking antibodies against the insulin receptor or genetically absent/reduced insulin receptor number/function.
Uncombable hair syndrome ( UHS) is a rare structural anomaly of the hair with a variable degree of effect. It is characterized by hair that is silvery, dry, frizzy, wiry, and impossible to comb. [ 4] It was first reported in the early 20th century. [ 5] It typically becomes apparent between the ages of 3 months and 12 years. [ 6]
Anagen effluvium 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. [1] [2] : 753–4. Anagen effluvium is due to an acute injury to the hair follicles by an endogenous or exogenous cause, resulting in sudden diffuse ...
Loose anagen syndrome, also known as loose anagen hair syndrome, is a hair disorder related to dermatology. It is characterised by the easy and pain free detachment of anagen staged hairs from the scalp. [ 5][ 6][ 3] This hair condition can be spontaneous or genetically inherited. [ 6][ 7] Loose anagen syndrome is primarily described in fair ...
Prepubertal hypertrichosis, also known as childhood hypertrichosis, is a cutaneous condition characterized by increased hair growth, found in otherwise healthy infants and children. [1] [2] Prepubertal hypertrichosis is a cosmetic condition and does not affect any other health aspect. Individuals with this condition may suffer with low self ...
When separating it from loose anagen syndrome or telogen effluvium, the hair pull test is frequently normal. [4] Normal physical exam (skin, teeth, and nails). [4] Average physical and mental growth. [4] The diagnosis is confirmed by microscopic analysis of the hair, which displays short telogen hairs with tapering tips, indicating uncut hairs. [1]
Non scarring hair loss, also known as noncicatricial alopecia is the loss of hair without any scarring being present. [ 1] There is typically little inflammation and irritation, but hair loss is significant. This is in contrast to scarring hair loss during which hair follicles are replaced with scar tissue as a result of inflammation.
