Dandruff & Scalp Conditions Explained
Similar to the rest of your skin, healthy scalps continually shed dead skin cells -- usually in small amounts that are hard to detect. When the delicate rhythm of skin renewal on the scalp is upset, too many skin cells are produced too quickly. The medical term for this increased shedding is "hyperkeratosis." Dandruff can range from Mild Dandruff, Moderate Dandruff, Severe Dandruff, and Seborrheic Dermatitis. You may notice dandruff worsening in cold, dry weather. But a dry scalp does not necessarily cause excess flaking. Less humidity in the air can lead to a reduced amount of oil on the scalp, which may keep flakes from sticking. Because they are being shed more readily, the flakes become more visible throughout the hair.
