Phalacrosis - the condition of having no hair on the top of the head, a synonym for baldness.It can result from heredity or hormonal imbalance or certain diseases or drugs and treatments (chemotherapy for cancer).

Symptoms of hair loss include hair loss in patches usually in circular patterns, dandruff, skin lesions, and scarring. Alopecia areata (mild – medium level) usually shows in unusual hair loss areas e.g. eyebrows, backside of the head or above the ears where usually the male pattern baldness does not affect. In male-pattern hair loss, loss and thinning begin at the temples and the crown and either thins out or falls out. Female-pattern hair loss occurs at the frontal and parietal.
