I’m 24, can I do a hair transplant

Your hair loss pattern appears to be a Class 6 pattern  possibly evolving into a Class 7 pattern (the arrows show the upper point of the balding consistent with a Class 7 pattern). For this, you need a doctor to measure your donor density and your hair mass index. This will give you a quantitative assessment of your donor capacity and what you must do as a worst case scenario (Class 7 pattern of balding) which must be part of your Master Plan for a hair transplant. Then your doctor will tell you what is your donor capacity and put together a plan (financial and surgical) that is specific to your situation now and in the future.
