As with normal hair, the growth pattern of transplanted FUs varies from one person to the next - some hair grows faster, other slower. There are so-called fast growers and slow growers, with some patients already clearly seeing results after just 6 months, and others having to wait more than a year.
In the first few days after an FUE transplant, thin scabs develop over the small incisions in the donor area. These disappear as healing progresses. Parallel to these scabs, most of the transplanted hair falls out in the second or third week after transplantation. Patients should not start worrying about this, as this is a completely natural process. The reduced intake of oxygen and nutrients weakens the transplanted roots, leading to the hairs attached to them falling out. As the hair roots are only weakened and not destroyed, new and strong hairs start developing after 3 - 6 months, once the roots have regained their strength. In certain cases, for instance when dense packing has been performed, there is a possibility of not just the donor hairs falling out, but also neighbouring hairs. These will also grow again once this hair loss period has ended. This so-called Shock Loss is a short-term phenomenon occurring in certain patients, probably triggered by operation stress.
The new hair roots start producing new hairs immediately after being transplanted. In the first three months, these are very thin, akin to flax. Afterwards the hairs get thicker and stronger and after about a year the end result is very visible. All transplanted follicles generally produce new hairs, although there are certain exceptions. These are fairly seldom.
