Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. There are various reasons for hair fall like: 1. Any stressful condition or any recent disease like malaria typhoid - if hair fall is due to this reason than its temporary and hairs will regrow soon 2. If you have thyroid disease- get thyroid profile done. 3. Vitamin D3 deficiency can result in increased hair fall - get serum vitamin D3 levels done 4. Decreased iron - get serum Ferritin done 5. A type of hair loss in male called Androgenetic alopecia is due to male hormone testosterone. It is considered to be age phenomenon and in this case hair loss can be prevented by taking anti androgen medications in low doses. Along with above you apply minoxidil 5 % lotion all over the scalp before sleep and take biotin pill. Till the time you are using above mentioned medications you will see improvement in hair growth and once you stop them they will be lost again. Take no stress eat balanced diet and do some exercise Hope I have answered your query. Let me know if I can assist you further.
