Ayurveda is the most ancient healing science and ideal approach for an appropriate life style. According to this science, proper choice of Ahara  and Vihara helps to achieve healthy life by maintaining and / or restoring equilibrium of the body and mind.

In Ayurveda, Shira is said to be root of the plant for possessing all special senses and Prana, so one has to protect and care the Shira. Acharyas have explained different Shiroroga out of which Darunaka is one among them. Acharya Vagbhata have described 19 Shiroroga out of which 9 are Shirokapalaroga and “Darunaka” is one among them. Acharya Sushruta has included “Darunaka” under Kshudrarogas. It is a Roga affecting mainly the Kapala,  that is scalp and it also hampers the normal healthy status of hair.Shirapradeshi Kandu (itching), Rukshata (dryness), Shirotwaka Sphutanam (cracking of the scalp skin with fine flakes), and Keshachyuti (hair-fall) are the cardinal symptoms of Darunaka which involves mainly vitiated Vata and Kapha Doshas.

Darunaka can be correlated with Pityriasis capitis also referred to as Pityriasis simplex capitis,  it is generally referred to as Dandruff. Pityriasis capitis is a disease characterized by itchy scalp and flakiness .Several microbial and non-microbial etiologies are considered for pathogenesis. Increased presence of Malassezia restricta has been reported as the key microbial etiological factor. Increased sebaceous gland activity, decreased skin hydration, skin irritation, immune suppression, or oxidative stress have also been proposed as non-microbial etiologies.

 Due to frequent recurrences, Pityriasis Capitis represented as a very common dermatologic scalp condition in a wide range of population with estimating prevalence of 60.1% in South Asia, whereas 50% worldwide.Pityriasis Capitis is a scalp disorder affecting more than half of the global population. A survey in the United States showed that 50 million people suffer from dandruff annually and the prevalence is sharply increasing due to rapid urbanization.It occurs more frequently in adolescents, young adults^.

Pityriasis Capitis is a scalp disorder with high rate of prevalence .There are many market preparations which are advised by modern dermatologists but it has some limitations as the effect is not long-lasting or cost of treatment is very high. As satisfactory results are not available, Patients are continuously looking with hope towards Ayurveda. Ayurveda plays an important role in the management of Darunaka as its unique treatment modality provides long-lasting results through three basic principles of treatment that is Nidana Parivarjana, Shodhana Chikitsa, and Shamana Aushadhis. Sthanika Chikitsa in terms of Lepa and Dhavana is also important in order to relieve the symptoms and nourish the hair.In present study one such formulation of Lepa which is given in Astang Samgraha Uttarsathana 28/33  is Priyalbeejadi Lepa(Trial drug) is taken to assess its efficacy on Darunaka wsr  to Pityriasis Capitis  and  compared with Aamrabeeja Haritaki Lepa (controlled)
