Scalp folliculitis is a skin condition that occurs when the hair follicles on the scalp become inflamed. ... A swab of the affected area may be taken to be looked at more closely under a ...
A new study published in the journal Nature analyzed genetic mouse models of nevi (aka moles) and found that two molecules—osteopontin and CD44—are responsible for hair growth that can happen ...
In addition to its role in defining human appearance, scalp hair also provides protection from UV sun rays and is an insulator against extremes of hot and cold temperatures. [1] Differences in the shape of the scalp hair follicle determine the observed ethnic differences in scalp hair appearance, length and texture.
A new study suggests that hairy skin moles contain molecules that promote hair growth, and may therefore offer a possible avenue to treat hair loss. Skin moles that grow hair may offer a treatment ...
A mole can be either subdermal (under the skin) or a pigmented growth on the skin, formed mostly of a type of cell known as a melanocyte. The high concentration of the body's pigmenting agent, melanin, is responsible for their dark color. Moles are a member of the family of skin lesions known as nevi (singular "nevus"), occurring commonly in ...
The underlying skin is unscarred and looks superficially normal. Although these patches can take many shapes, they are usually round or oval. [19] Alopecia areata most often affects the scalp and beard, but may occur on any part of the body with hair. [20] Different areas of the skin may exhibit hair loss and regrowth at the same time.
Others may warrant more thorough examination and biopsy for histopathological examination (looking at a sample of skin under a microscope to detect unique cellular features). For example, a clinician may want to determine whether a pigmented nevus is a type of melanocytic nevus, dysplastic nevus, or melanoma as some of these skin lesions pose a ...
