Hi Anduser. Sorry to see you have suffered this much hair loss at a young age.
At what age did you begin losing your hair?
As the other members have mentioned the medications may help to prevent any further loss and may regrow dormant and miniaturised hairs. Without them, you could continue to lose more hair or you may stay as you are, no further loss without the use of meds. The side effects are something you need to look into, only a small percentage of users get them but if you fall into that category you may have to stop using them.
Do you have a picture of your donor area? Some people do have very dense donors allowing enough grafts to be extracted so when transplanted will make a nice cosmetic improvement to your appearance but you`re not going to have a full head of hair and could regret having a HT if you`re not happy with the look. There is SMP if you want to have a full head of hair shaven look, this will require maintenance top ups.
What are you wanting to achieve?
