Factors like age, forhair clinic, and hair loss progression help answer this question. The person receives more than one treatment in most cases, although it may take several years between them. The quality of the hair transplant performed will determine the need for additional procedures. If the treatment is of higher quality, the longer it will last and the longer the time between hair transplants will be available.
It realy depends on age and the degree of hair loss, The younger the patient, the greater risk to lose more natural existing hair after the hair transplant. This can be minimized by taking DHT blockers such as Finasteride (propecia) or Topical Finasteride with the combination of Minoxidil, These treatments can prevent and block further hair loss to existing hairs. Most of the patients will need one or more passes at some point of their lifes if they want to maintain high density.
