Can I use caboki or toppik hair building fiber on FUT scar within a month after hair transplant? (Photos)

The cost of hair transplant surgery differs from doctor to doctor / from clinic to clinic.  It is best you see different doctors in your area.5000 grafts is an unusually high number of grafts (for a single surgery).

Transplanted hairs behave like hairs from where it was taken. If the donor hair is healthy, the transplanted hairs will remain healthy.

It is best to see a doctor for consultation to make sure your goals and expectations can be met.  Just adding hairs may not give you the "density" that you can notice.

Photos cannot diagnosis your hair loss. The old fashion way of seeing a doctor in person for an examination is still the best method.  

Hair transplant surgery is not about "how many grafts" you need, but about how a doctor can match your goals and expectations based on future hair loss.

There is no issue with drinking green tea after surgery unless your doctor recommends avoiding caffeine.
