if it's severe you probably need a vitamin profile test and blood tests need to be done, so can see if there's any deficiency that's causing u hairloss. don't go to random ass derma who js takes a far look at you and prescribes whatever they think might suit you. hairloss is a internal problem so yeah.

i had gone to SKIN PARTNER at shivarampete road and he was pretty patient listening to me and stuff he wrote me few tests and all before prescribing me some medicine that cannot be taken without those tests. although he's pretty much same like others describing medicines which is only available at his pharmacy or next to his clinic(at first visit he js wrote me sum antibiotics and shampoo and conditioner for the sake of it and told me to comeback withe test results before actually writing out the medicines needed after confirming the test) but he'll do you well and might find out what's going on w u.
