Can You Get a Hair Transplant On Your Whole Head?

Hair transplants have become an increasingly popular procedure for those that experience premature balding and thinning of hair. While this is an incredibly popular procedure it is not without some caveats. The requirements for a successful hair transplant are numerous so it is important to have a consultation with the physician carrying out the procedure to see if a hair transplant is the right solution for you. Some factors that can make a person ineligible or have a reduced chance of success include patients who are undergoing chemotherapy and experience chemotherapy associated hair loss, people with widespread baldness and thinning such as men with diffuse unpatterned alopecia and women with androgenic alopecia, those addicted to drugs that have drug associated hair loss, and those that are completely bald. All of these issues are less likely to yield good results in those looking to get a hair transplant because hair transplants actually require the individual to have regions of relatively high follicle density. This is crucial because hairs are taken from densely packed areas of hair and transplanted to areas of thinning or balding. Below is a breakdown and answer to the question of can hair transplant cover whole head.

Why do you need hair to fix baldness

This point may seem counterintuitive to those unfamiliar with the process of a hair transplant. A hair transplant can be thought of more like a hair migration procedure. Hair is needed for a procedure to fix balding because hair transplants take hair from one area of the head and place them into balding sections of the head to correct male and female pattern baldness and thinning. More specifically the individual needs to have areas of relatively high hair density because the areas of high hair density is where the follicles are taken from. This is to give a more natural appearance because if you have thin hair around the entire head, if you take follicles from these regions it will be noticeable and will actually result in a relocation of the thinning to the region where the follicles were extracted. Hair transplants are a good option for a large percentage of the population that suffers from balding but it cannot be done on every balding person for the reasoning described above. The main reason it works is because typical male and female pattern baldness tend to only impact the top of the head, leaving the back of the head full of follicles wi=hich results in a perfect candidate for extracting follicles discreetly.

Why can’t you cover the whole head

The answer to the original question is that a person cannot have a hair transplant procedure to cover the whole head. The main reason is that a person needs to self supply all of the hair being utilized in the procedure. These follicles need to be from the patient as they will not only look the most natural, but they will also have higher likelihood of integration into the new area of skin. If there was a technique where people could use other follicles it would face issues like coloring and thickness differentiation from the naturally occurring hair and would be more likely to undergo rejection much like organ transplants can be rejected by the body. The easiest way to think about a hair transplant is to think of it as a nursery with 100 trees growing. Let’s say the trees are uniformly distributed in a field and 5 or so of the trees begin dying in one region of the field. The remaining trees can be rearranged to create a field that looks largely similar to the field before but less densely packed. The more trees that would die in the situation, the less dense the field would become. With this analogy, a more dense field correlates with normal appearing hair while a less dense field is correlated with thinning hair. The process of hair transplant is a balancing act of trying to achieve a natural look by extracting and implanting follicles into vacant regions without creating an appearance of thinning.  Going to the surgeon that will perform the procedure before deciding to take the plunge will give you a better idea if your particular situation can receive good results from the process or not. 

In short, hair transplants cannot cover the entirety of someone’s head. The need to have regions of donor hair is the reason why hair transplants cannot cover the entirety of a person’s head. While transplants can be placed anywhere on the scalp, they are not able to cover the entire head at once. Not only is this not possible for the reasons described above, but it is also unrealistic because of the length of time the procedure would take a person to conduct. Typical transplant procedures can take 5 hours or more and this is for populating relatively small areas with follicles.
