Why Does Getting the Same Number of Hair Grafts Transplanted Result in a Different Amount of Hair?

A hair graft is a collection of tissues or cells containing hair strands used in hair transplant procedures. Typically, each graft contains between 1 and 4 hair strands, and people naturally have varying sizes of grafts. The hair grafts typically used for transplantation come from the back of the head or occipital area, where the follicle cells are permanent and usually yield satisfactory results when transplanted. However, hair grafts can also be harvested from other areas of the body, such as the pubic area, armpits, chest, shins, or beard. The doctor will determine the number of grafts required and the most suitable method before proceeding with the hair transplant procedure.

Why does transplanting the same number of grafts result in different amounts of hair?

Let’s explore the question we mentioned earlier: why does receiving the same number of hair grafts during a transplant sometimes result in varying amounts of hair growth? For instance, Mr. A received a 500-hair graft transplant and achieved 1,000 hairs, while Mr. B received the same number of 500-graft transplants but only grew 800 hairs after treatment. Contributing factors to such differences include the number of hair strands in each graft, which can range from 1 to 4 strands, as well as hair thickness, as people with thicker hair tend to achieve more noticeable results.

However, there are more crucial factors associated with hair growth and outcomes after transplantation, including:

1. The period of time the hair grafts are outside the body before transplantation

An experiment conducted by Dr. LIMMER involved immersing hair grafts in chilled saline prior to transplantation. The results of the experiment showed that the longer the hair grafts were immersed, the lower the chances of hair survival or growth into strong hair.

2. The liquid solution used to immerse hair grafts

The liquid solution used to immerse hair grafts is another factor that can affect the success of transplantation. An ideal solution must have properties that can maintain the grafts. Popular solutions include HYPOTHERMOSOL, LIPOSOMAL ATP, ACELL, or CHILLED SALINE.

3. Temperature and moisture for hair storage

The appropriate temperature and moisture levels for storing hair strands are key factors that can affect the results of hair transplantation. The optimum temperature for storage is 4 degrees Celsius, and the humidity must be maintained at a high enough level.

This answers the question of why hair transplantation with the same number of grafts can result in different amounts of hair.
