Causes of Hair Loss. First your doctor or dermatologist (a doctor who specializes in skin problems) will try to determine the underlying cause of your hair loss.

Demand Elasticity - the degree to which changes in price effect changes in demand. Demand is elastic when a small change in price effects a large change in demand. Such products, that show great variability in demand are known to have elastic demand.
Price Elasticity of Demand. An important aspect of a product's demand curve is how much the quantity demanded changes when the price changes. The economic measure of this response is the price elasticity of demand. Price elasticity of demand is calculated by dividing the proportionate change in quantity demanded by the proportionate change in price. Proportionate (or percentage) changes are used so that the elasticity is a unit-less value and does not depend on the types of measures used (e.g. kilograms, pounds, etc).
