During the first 3 months after the surgery, the transplanted hair will fall out. This is a normal part of the hair growth cycle and should not be a cause for concern. After this shedding period, new hair will begin to grow in the transplanted area. The new hair will be very fine and short at first, but over time it will thicken and grow longer. At 6 months post-surgery, the hair will be longer and will look more natural, but it will still be relatively sparse. It will still take time for the hair to reach the desired density. After about 9 months, the hair will have reached its final length and will be thicker and more dense. After a year, the transplanted hair will have fully grown in and will look natural. The hair will be thick and long, and it will be difficult to tell that the person has undergone a hair transplant. The hair will continue to grow and be maintained through regular hair care practices such as shampooing, conditioning and vitamin supplements. It's important to keep in mind that the growth of transplanted hair may vary from person to person, and some people may experience faster or slower growth than others. Also, 1-2 years after the hair transplant, the hair will be fully grown in and the patient will have a full head of hair again.
