Hair fall will b resulted from many reasons like Less nutritious food intake,Any skin allergies,Dandruff(again there r types),Usage of some h8gh concentrated shampoos,Hard water,Hair T/ts,Dye usage,Any harmonal Imbalance,less Hb levels,Heriditary.....etc any of these.So,taking care in that aspect will give good results.Ultimately u can go for Medication (based on reasons)parallelly will do good.I suggest Homeo as no side effects.
