Background: Skin constantly renews itself. Dead cells fall off as new cells form beneath them. In Pityriasis capitis, this process is abnormally accelerated. Its signs and symptoms are: cells shedding in clearly visible flakes, small white or grey scales accumulating on the scalp, itching and dry or greasy hair. Darunaka is disease described in Ayurveda under Ksudra Roga. Signs and symptoms of Darunaka are: Daruna (cracked scalp), Kandura (itching of the scalp) and Ruksha (dryness of the scalp). Darunaka can be correlated with Pityriasis capitis. Aim: Sri Lankan use Siyakkai (Acacia concinna) hair wash (SHW) as an effective home remedy for Pityriasis capitis. No known scientific study has been undertaken to evaluate the efficacy of SHW. Hence, the present study was undertaken Methods: SHW is prepared by adding 10g of powdered pods of Acacia concinna to 240ml of boiled water. Seventy patients having Darunaka were selected and randomly divided into two groups, named as Groups A and B. Group A, consisting of thirty five patients, was treated with 240ml of SHW every alternative day, for twenty eight days. Group B, consisting of thirty five patients, was treated with placebo, in the same regimen. Response to treatment was recorded and therapeutic effects were evaluated through symptomatic relief. Results: Patients treated with SHW showed a significant symptomatic relief in scaling, itching, dryness and greasiness of scalp after treatment. Interval between scaling also became longer. Some patients treated with SHW complained of rhinorrhea. Conclusion: It is concluded that Darunaka (Pitiriasis capitis) can be relieved with Siyakkai Hair Wash.
