It is the most common situation, and that’s why many people are very curious to know about this condition. As we all know that normal hair follicles cycle are consist of three different phases known as the anagen (growth) phase, the catogen (transition) phase, and the telogen (rest) phase. When a surgeon transplanted hair from the universal safe zone to balding areas of scalp, hair follicles are often in different phases and certainly enter into the “resting” phase at different times according to the situation. Because of this reason, implanted hair grafts naturally mature from “fine and thin” and they start to grow in (roughly) 3 months and natural full grow within 12 months, but some time due to some unexpected reasons this growth phase starts at different times as well.
Because of this unexpected growth delay, seeing certain areas of the transplant grow and mature at different rates is perfectly normal and natural. If one part of the transplant portion seems like it is growing slower or appears “different” than the others part of the scalp at the 3rd, 6th, or even 8th month mark then, patients must be rest assured and simply wait until month 12. After 12 months, the transplanted hair grafts should be fully matured (though some argue it can take 14-18 months) and all regions should appear full, thick and natural.
