Hair Transplant Before Age 30? Can't use Finasteride/Minoxidil due to sides

It would be difficult to advise on if you should or should not have surgery without an examination and better understanding of your goals.
Patient #1 may be a great candidates if their expectations are reasonable.
Patient #2 (with the EXACT  same hair loss pattern) may be a bad candidate because their expectation or goal was not realistic 

Hi TyronAmanten,Thank you for posting your question on realself.com. I often have patients move forward with their hair Restoration before the age of 30. The medications minoxidil and/or finasteride are recommended for most patients, but not required. Other options to minimize further loss include the LaserCap and/or PRP. SMP might be utilized to reduce the amount of contrast between the color of your skin and hair. Bernardino Arocha, MD, FISHRS

 there is no time limitation or restriction for  HT, yes  of course you may have  a hair transplant surgery to fill the bald area on crown . there is no need to wait more for that surgery , you need that now! It is better to see your photos  in order to estimate how much graft do we need to cover area. 

Apart from the regular hair loss solutions like Finestride and minoxidil, hair transplant is the only permanent solution to hair loss or male patterned baldness. Yes, a hair transplant can be planned to use the grafts judiciously and save some donor area for the future transplants, if the need arises. Consider consulting a few hair transplant surgeons to discuss your options. 

At 30, you can easily get a hair transplant into the crown. See a doctor who will measure your donor density and build a Master Plan for you transplant now and in the future as you may need more transplants if further hair loss occurs. I had my crown done and never needed frontal work.
