Unlike other processes, with a hair transplant, there is no result at night. In fact, the benefits of transplantation will only be visible several months after the date of the operation. Two to six weeks after surgery, the transplanted hairs fall and we cannot say that something has been done. Some patients also suffer from loss of electroshock when existing hairs fall due to the trauma suffered by the scalp during the procedure. This is temporary and the hair will grow back quickly.
What is the growth rate of grafts after a transplant?
New transplants can start growing in just 2 months, but this is mostly rare. Transplants require an average of 6 to 12 months to start developing. Occasionally it may be necessary to wait up to 18 months after surgery.
From 3 to 18 months after surgery, the transplanted hair begins to grow like fine hair. Over time, transplanted hair becomes thicker, thicker and thicker. At the beginning of the grafted follicular unit (this natural group of hair that normally grows in single, double or triple) grows like a single hair, but it will become double / triple or does not matter when it has been transplanted.
In the end, all this waiting is rewarded. The transplanted hairs start to thicken and the results tend to coincide or exceed the patient’s expectations. Although the results of a hair transplant are not immediate, when new hairs arrive, it really becomes a change of life for the patient.
Several factors that influence the time needed for hair growth after a transplant
The transplanted hair grows at different speeds depending on the patient. The time required for the growth of grafts depends on some factors:
- Blood supply: when the transplant is carried out, the cells send signals that promote the growth of new blood vessels. These blood vessels, in turn, supply the follicle with the nutrients it needs to produce healthy hair. The necessary time varies from person to person. For example, a person with a basic condition such as diabetes or high blood pressure may take longer because these conditions have a negative effect on blood supply. But in the end, the inactive transplant will receive the blood, which will provide the “food” necessary for its growth.
- Growth phase: the hair passes through three phases: Anagen, Catagen and Telogen. During the anagen phase, the hair grows. This growth lasts between 2 and 6 years under normal conditions. During the catagen phase, the follicle starts to break away from the hair. The catagen phase usually lasts only 2 or 3 weeks. Finally, during the telogen phase, the hair falls and the follicle remain inactive for 1 to 6 months. Normally, 50 to 150 hairs can fall every day and 10-15% of the hair is telogen at some point. The transplanted hair can continue initially in the anagen phase. However, the transplanted hair will soon be changed to Catagen and then into the telogen phase. It is at this moment that the hairs of the grafts fall. Time spent by hair in the telogen phase will affect the time required for new hair growth. The duration varies from one patient to another.
How much you “helps your grafts”
Another important factor is what you do as a post-transplant patient to encourage hair growth. It is essential to follow the instructions given by the doctor. Some of these guidelines include: a diet, after transplantation and regular exercise (once approved by the hair transplant surgeon). FDA-approved lasers can also help stimulate new hair growth. Avoiding smoking is also essential because nicotine will discourage the proper development of blood supply. Avoiding excessive sunlight will also help. A complete list of “things to do” and “things to do” will be provided before surgery, but these are some of the most important guidelines.
