Seborrheic dermatitis is a chronic, erythemo-squamous disorder affecting scalp, face and mid line of the chest and back, found in 3% to 11 % of the population worldwide. There is growing evidence that vitamin D may play beneficial role in therapy of this common condition.
We studied 32 patients (16 males and 16 females) aged from 18 to 64 years with proven vitamin D deficiency (serum 25 (OH) vitamin D lower than 21ng/l) who were supplemented with 1600IU cholecalciferol per day for 3 months. Patients filled in a form with the number and duration of exacerbations of seborrheic dermatitis they experienced during the trial period.
The number of recurrences of SD during the period of vitamin D supplementation was reduced in 21 patients (65,6%). No change in the rate of worsening was found in four female and three male patients. Four patients observed an increase in the frequency of the exacerbations
