Don't worry usually upto 3 months people don't see any growth....you will start seeing more hairs sprouting our after 3 months when the shedding phase pass out....thn those baby hairs will start maturing and start getting fuller and thicker but that will take time...the real difference can usually be seen after 8 months post op...so hang on brother..i know its tough to wait so much bt there is nothing much we can do other than religiously being on medication and i hope you are doing that...even i am in the waiting phase as i had my surgery on 2nd may..this waiting game sucks
Happy growing and keep updating
