Although traditionally associated with the scalp, poliosis can affect any hairy area on the body, including eyebrows, eyelashes, and beards. Microscopically, poliosis is marked by the lack of melanin or melanocytes in the hair bulbs, though epidermal melanocytes typically remain unaffected unless associated with conditions like vitiligo.

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 ...
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 ...
Skin Swab: A swab of the affected area may be taken to be looked at more closely under a microscope. This helps to identify the specific bacteria, yeast, or fungi causing the infection.
Traction alopecia is a type of alopecia or hair loss caused by a chronic pulling force being applied to the hair. [1] It commonly results from a person frequently wearing their hair in a particularly tight ponytail, pigtails, or braids with increased likelihood when hair is chemically relaxed as this compromises the hair shaft's tensile strength resulting in hair breakage.
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 ...
This skin lesion is quite common in the population, and it can present at birth, known as a congenital meloncytic nevus, or later in life as an acquired nevus. Should the nevi appear in toddler- or school-aged children, they are more likely to remain present throughout the rest of that person's life. [ 4 ]
A woman who noticed a black mole on her scalp that turned out to be melanoma, the deadliest form of skin cancer, said doctors initially dismissed her concerns. Skin Cancer On Woman's Scalp ...
