I am gradually having a lot of dandruff and hair fall, like around 200+ strands breakage in a single go. This happened while I went through pcos treatment. A consulted a doctor where he suggested me mintop 2% or more 3%. But I am really afraid to use it. Because I have read people saying that it has to be used life long once stopped again hair fall starts. Will I have to use it throughout my life? Is it safe for me to use?
