Scalp Conditions and Hair Loss
There are several scalp conditions that can cause an itchy scalp, hair loss, and flaking; most can be treated with topical scalp meds. Among the most common is dandruff, which causes dead skin cells to flake and fall from the scalp onto the shoulders. Although it is a nuisance and is unattractive, this condition is primarily cosmetic; it does not result in a dry scalp, hair loss, or other serious consequences, and can generally be treated using dandruff shampoos that contain ketoconazole, zinc pyrithione tar or selenium oxide.
Other common conditions include excessive oiliness (seborrhea), and oily crusts adhering to inflamed, itchy, moist scalp skin (seborrheic dermatitis, also known as cradle cap in infants). The latter condition tends to be the most severe and should be treated by a dermatologist or other physician. However, an itchy scalp and hair loss rarely go hand-in-hand. However, regular scratching of the scalp can lead to hair breakage.
Baldness (alopecia) secondary to certain dermatologic diseases or scalp injury and subsequent scarring is called cicatricial or scarring alopecia. In medical terminology a scar is called a cicatrix.
Weathered hair is caused by excessive sunlight, excessive wetting, chemical and physical damage and hair shaft damage. Weathered hair, like weathered skin, detracts from your appearance and makes you look older than your actual age.
The most common conditions of the human scalp are flaking dead skin cells (dandruff), excessive oiliness (seborrhea), and oily crusts adhering to inflamed, itchy, moist scalp skin (seborrheic dermatitis).
