Trichororrhexis Nodosa of the Scalp Attributable to Calcium Hydroxide.


A 30 years old maly complaining of loss of 1-2 cm long fragments of hair from his scalp, was discovered to have trichorrhexis nodosa involving approximately 40% of his scalp hairs. The defect was located 1-4 mm proximal to the distal ends of the hairs and was attributable to the topical application of calcium hydronide in an ayurvedic preparation.
