Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain it seems that you are suffering from Seborrheic Dermatitis commonly known as Dandruff and common causes for it can be fungal infection, genes, change in weather, poor hygiene conditions, poor immunity etc.. Experiencing hairfall along with it seems to be probably due to damage of hair follicles with dandruff.. I would suggest you to consult a Trichologist and get evaluated and a thorough clinical evaluation and microscopic examination of the flakes can help in diagnosis and treated accordingly.. You can be advised to apply shampoo containing Ketoconazole, coal tar, salicylic acid, zinc, selenium, sulfides etc.. You can also be advised to massage the scalp with steroid lotion.. You should also keep the scalp clean and avoid moisture accumulation to prevent infection.. You can also take biotin and multivitamin supplements as it helps in reducing hairfall and promoting hairgrowth.. Add more of green leafy vegetables and fruits in diet.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
