ABSTRACT
Hair casts are often present in the hairs surrounding the alopecic area (Figure 13.6). Tension headache is very common in women wearing a ponytail (more than 50% of cases).
Repetitive friction produces hair breakage and patchy hair loss (Figure 13.7a,b). This may be a consequence of scratching, rubbing or even overzealous application of hair lotions. Scalp or body hair may be involved (Table 13.2).
