Is a dry, brittle condition, which includes the formation of nodular swellings in the hair shaft. The hair is rough to the touch and may be broken. Chemicals and physical damage can cause this, for example the rubber bands on perming rubbers. Treatment should include restructuring hair products and conditioning; where possible hair should be cut out.
