Homeopathy can treat skin diseases (including hair and nail issues) very effectively. Its holistic approach is helpful in treating skin diseases of various names like psoriasis, lichen planus, herpes zoster, eczema, urticaria, etc to name a few. It treats not by the name of the diseases but understands the person as a whole and hence it is helpful in various conditions like bullous pemphigus, hidradenitis suppurativa etc. Various researches are confirming the efficacy of homeopathy in treating skin and hair diseases.
It is better to avoid any local application during homeopathic treatment for mainly 2 reasons:
1. It will only mask the symptoms and the physician does not know if the holistic internal medicine is helping and to what extent.
2. It sometimes suppresses the skin complaints altogether and the disease force is directed towards some internal organ sooner or later.
