Number 1. Graft Damage By Clinic
Follicular unit grafts are living organisms that must be handled delicately with the utmost care. The grafts must be kept moist, so that they don't dry out and die. In addition, the grafts can not be out of the body for a prolonged period of time or they will die. Generally, graft damage occurs when the surgeon is extracting or transplanting the grafts. If the clinic/surgeon doing the procedure is inexperienced and unskilled they may damage the grafts when placing them in to the recipient sites. This is why selecting a competent, skilled and experienced hair transplant surgeon is so important. Ultimately, the surgeon selection will directly impact the overall aesthetic and cosmetic outcome of the result.
Number 2. Complications After Surgery
Sadly, it is not always the surgeon or clinic staff that damages the delicate follicular unit grafts. Unfortunately, patients are also responsible for damaging their grafts and compromising their hair growth. It is important that patients treat their grafts delicately for the first seven to ten days, because this is when the follicular unit grafts are at risk of becoming dislodged and ultimately lost. If a patient dislodges their grafts it will always result in a lost graft, which will reduce the overall growth and yield of the result. In most cases, patients dislodge their grafts due to scraping or bumping their head. Sometimes patients will wear tight fitted hats or beanies right after surgery, which will tug and dislodge the grafts as they are pulled off. Patients should be mindful and treat their newly transplanted grafts with care. Also, infections and adverse reactions to certain anesthetics can hinder the yield of the result, but this rarely occurs and can be mitigated with medications.
Number 3. Factor X
In spite of a surgeons best efforts and surgical techniques, poor growth can occur even when patients have followed proper post-operative care. So what is the reason? Well there can be several reasons that may not always be apparent to the surgeon or patient. Sometimes the reaons for poor growth can be due to the patients growth characteristics. Hypertension, diabetes and smoking can all attribute to poor growth. Additionally, some individuals may suffer from hypervascularization which is common in chronic inflmmatory conditions. This is why no hair transplant surgery can ever be guaranteed, but with a healthy lifestyle and a talented, skilled and experienced hair transplant surgeon the odds of a failed procedure can be significantly reduced, but never guaranteed.
