Hair loss patterns can vary greatly. Some men are lucky and only suffer minor hairline recession. Others lose all the hair over the top of their head. How can a hair transplant work? Being able to treat minor to advanced hair loss. Especially when there is a limited supply of hair to use.
Hair loss is permanent. It doesn´t grow back if genetic hair loss.
When the hair is taken from the donor it is gone. It doesn´t regrow back in the donor.
We can´t match the original hair density or replace like for like hair lost
So, how does a hair transplant work if you can´t replace all the lost hair?
Hair transplants need hair. The hair needs to be taken from the donor area. There are two techniques used for removing the hair. The hair transplant techniques, Follicular Unit Transplant or Follicular Unit Extraction. Both rely on the number of grafts placed to give a result. But more important is the number of hairs per follicular unit (FU).
The medical and artistic placement of the FU´s in a skilled manner will get the most thickness and coverage from each group of hairs along with help from their natural hair characteristics. The angle, orientation, and the lay of a hair are placed are all important to how natural and how much coverage a hair unit will look and give.
Getting the most from each group of hairs is important. Otherwise, a hair transplant would not work. If coverage and density could not be achieved with less than a full head of hair then a hair transplant wouldn´t work.
Depending on the area of the head. The number of grafts and the size of the hair units. This will change planning. From the hairline to the mid-scalp area to the crown. All areas require planning and taking into account the hair characteristics. As a result, it´s possible to achieve natural hair coverage even on advanced hair loss patterns.
Hair distribution is the key to a good hair transplant
A hairline will typically require 600-800 single hair follicular units, FU´s. If the temple points need to be rebuilt the number can rise. To close to 1000 grafts. is can be over 1000. This will create a natural soft looking hairline. Opposed to a pluggy look from poorly placed and large hair grafts.
Behind the hairline, larger hair units are used with 2 to 3 to 4 hair FU. If a greater number of single hairs are placed in this area it will reduce the surface area distribution.
Naturally, some people have smaller hair numbers (groupings) per FU. As a result, in some cases, this may mean they not suitable for a hair transplant. So it is very important that when graft numbers are calculated. The hair count is also a consideration.
When the donor hair is mentioned. Often it is in relation to the hair density. Even a high FU density can mean a poor donor area. If only made up of mainly 1 and 2 hairs per follicular unis for example. Opposed to an average density made up of a good number of 3 and 4 hair FU.
Ensure when you research your hair restoration you question the hair density. Including the hair numbers.
