How Does A Hair Transplant Work?

This article is going to focus less on the medical aspect of genetic hair loss and how some hair is immune and some are not, but instead focus on how it is possible to make someone look like they have a good head of hair with so little hair used.

Some facts

Hair loss is permanent it doesn´t grow back if genetic hair loss

If we take it from one place and move it to another it´s moved… it doesn´t regrow again

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?

Regardless of the hair transplant technique used, 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 will change to achieve to the desired results, from the hairline to the mid-scalp area to the crown. All areas require planning and taking into account the hair characteristics to ensure it is possible if hair loss progresses to an advanced stage a natural coverage and hair density can be achieved.

Hair distribution is the key to a good hair transplant

A hairline will typically require 600-800 single hair FU and if there is temple point rebuild this can be over 1000. This will create a natural soft looking hairline rather than 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 and in some cases, this may mean they not suitable for a hair transplant; so it is very important that when graft numbers are concerned it is in relation to the hair numbers.

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 if only made up of mainly 1 and 2 hairs per follicular unit, opposed to an average density made up of a good number of 3 and 4 hair FU.

Ensure when you research your hair restoration this is addressed and understood what is a hair graft and how they will be distributed from your hairline back, and that your donor hair is strong enough to treat hair loss in the future if your hair loss progresses.
