Is a protein filament that grows from follicles found in the dermis. Hair is one of the defining characteristics of mammals. The human body, apart from areas of glabrous skin, is covered in follicles which produce thick terminal and fine vellus hair. Most common interest in hair is focused on hair growth, hair types and hair care. But hair is also an important biomaterial primarily composed of notably alpha-keratin and protein. Attitudes towards different hair, such as hair removal, vary widely across different cultures and historical periods and different cultures, but it is often used to indicate a person's personal beliefs or social position, such as their sex, religion also age.
Hair fibers have a structure consisting of several layers, starting from the outside:
- The medulla, a disorganized and open area at the fiber's center.
- The cortex, which contains the keratin bundles in cell structures that remain roughly rod-like.
- The cuticle, which consists of several layers or flat, thin cells laid out overlapping one another as roof shingles.
5 MOST COMMON HAIR PROBLEMS
Common problems affecting the hair and scalp include hair loss, infections, and disorders causing itching and scaling.
Hair loss (alopecia) is a frequent concern for both men and women, although it is normal to shed some hair each day. People who experience more than normal hair loss may have the inherited tendency to "common baldness." Male pattern baldness is the most common cause of hair loss in men, with a receding hair line and baldness on the top of the head. Women may develop female pattern baldness in which the hair becomes thin over the entire scalp. Sudden and temporary loss of a large amount of hair may be related to the stress of an illness or recent delivery of a baby (telogen effluvium). Alopecia areata causes hair loss in small, round patches while tight elastics or braids may cause hair loss at the hairline (traction alopecia). Certain diseases (eg, thyroid problems, diabetes, and lupus), medicines, or poor nutrition may also cause hair loss.
Infections of the scalp include bacterial infection of hair follicles (folliculitis), infestation of head lice (pediculosis capitis), and fungal infection of scalp ringworm (tinea capitis). Itching and excessive flaking of the scalp is seen with both dandruff (seborrheic dermatitis) and psoriasis.
