Nobody is going to reply within a minute, especially at this time. For a question as generic as that, options are:
Finasteride- blocks DHT and stops/ slows down hair loss. Sometimes promotes regrowth.
Minoxidil- Regrows hair but does nothing to stop more hair falling out.
Transplantation- Always do research before this- it isn't for everyone
Concealers- Temporary and need to be applied daily i.e. toppik hair fibres/ dermmatch. Disguise hairloss either by sticking to existing hair and thickening it or colour the scalp to blend in with the hair.
Micropigmentation- Basically a permanent concealer. Uses permanent ink to create small dots creating a shaved look. The hair would have to be shaved for this to work though.
Wig/ hair pieces- Wear them.
Basically search this site and see what people are doing, the success stories is usually a good place for options that work. Also, if you're a troll which you probably are, this really isn't a brilliant place to troll.
