As previous comment , it's best to consult professional.
Beacuse without proper information, you do not know the cause of the hair fall. It might be just natural but longer strand makes it more visible.
I think the only possible cause of chemical uses is chemical burn, but you should feel burning sensation to it. Not sure if there are still help if damage is done through.
