One of the first things you may ask your doctor is if the results are permanent. Why go through with a procedure when you’ll just have to get it redone later? So is the hair transplant permanent?
Similar to any other transplant, hair restoration is done by redistribution. In this case, we move and transplant hair follicles. We move DHT resistant hairs to replace the fallen and thinning DHT sensitive hairs. The results are expected to be long lasting, and usually last a lifetime. But, outside factors may affect the staying power of the hair (regardless of DHT sensitivity).
Things that can affect the hair externally includes going through trauma or chemotherapy. This can cause a different pattern of hair loss that is general and more diffuse(think of the classic cancer patient on chemo). The good new is that these do seldom cause continued hair loss once treated and managed. However, these medical conditions do need to be accounted for in any hair transplant procedure.
However, barring chemotherapy and major medical conditions most people are in good shape. The good thing about transplanted hairs is that they do not fall out due to the same reasons your native hairs fell to cause male pattern hair loss i.e DHT because of DHT. This is because transplanted hairs are DHT resistant. So general medical disease will cause general hair loss, but male pattern DHT prone hair loss only affects your native top of scalp hairs but not the transplanted hairs. This means you get to keep your new hairs for a long time.
The doctor will help try to get long-lasting results and go over all the details when you are seen for a consultation. This way, the doctor can see what the best route is in your specific case by examining your donor and recipient sites as well as what kind of hair loss you have.
Remember, not everyone is the same so every procedure will be different from the last. Many other factors play into deciding the route you should take when getting a procedure done. Don’t be afraid to ask questions and make sure that you do speak to your hair physician about your situation.
