If you are getting treated by an allopathic dermatologist please do not try to create a home made pack because unfortunately there is no quick fix solution . There is no formula for the perfect hair care product. Talk with your dermatologist and try to find out what suits you the best. This takes time and you will need to be a little patient . Also rinsing with water only doesn't clean the scalp or the hair. Do not be scared to use a shampoo or conditioner. Again, ask your dermatologist and I am sure uou will get answers. http://www.skinmatra.com/single-post/2016/11/10/Hair-Woes-10-Things-You-Should-Know-About-Hair
