Hair transplantation operation is a non- surgical procedure, in which hair follicles are transferred from the donor area, i.e. the back of the scalp, to the receiving area; i.e. the bald areas to be treated.

There are several key techniques used in hair transplantations:

1. (FUE) Technology
   With this technology, the follicles are picked out from the donor area via the Micro Motor, and transplanted into the receiving area by opening fine channels in the bald areas with precise medical forceps. The operation takes around (6-8) hours, transplanting up to (4000) follicles.
2. (Mega FUE) technology
   Mega FUE is undergone over two sessions during two consecutive days, transplanting a maximum of (8000) follicles, and giving the hair more density.
3. (Ultimate FUE)
   Ultimate FUE differs from FUE in terms of the medical scalpel which is made of fine blue sapphire that prevents damage to the scalp during the picking process.
4. (DHI) Technology
   The doctor opens channels in the areas of baldness that due to be treated with Choi Pen Implanters, then he implants the extracted follicles which are up to (3500). He does all this simultaneously with one click. The whole process takes around (6-8) hours.
5. (Mega DHI) technology
   The (Mega DHI) technique is performed over two sessions during two consecutive days, using the Choi pens. However, with (Mega DHI), a maximum of (7000) follicles are transplanted, giving the hair more density and attractiveness.
6. Extremely DHI Technology
   Extremely DHI Technology goes through the same stages of DHI technique, however, it enables the doctor to transplant up to 5000 follicles during 12-15 hours over only a session.
   

The candidates for hair transplantation are:

1. 1. People who suffer of severe hair loss and hereditary baldness.
   2. People who have a strong donor area.
   3. People with good health, who do not suffer of certain diseases that may impede hair transplantation.
   4. People older than 22 year of age.

There are some important tips that one should stick to before undergoing hair transplantation process:

1. Avoid smoking for at least two weeks before the procedure, as it affects the growth of the follicles and affects the results of the process.
2. Avoid drinking green tea, for it is a blood thinner that causes severe bleeding during and after the operation and leads directly to the failure of the transplantation.
3. Avoid coffee and stimulants in general for at least four days before the transplantation, because they are stimulants that affect the anesthesia process.
4. It is recommended to eat a healthy and balanced food well before the operation, in order to avoid any complications occur during or after the operation.
5. Stop taking medications that cause blood thinning, such as Aspirin and ibuprofen combinations.
6. If you are having certain medications for a particular disease, such as hypertension, diabetes or other diseases, your healthcare professional who is following your health condition must be aware of and approved the hair transplantation process.

There are a set of tips after the hair transplantation process that must be followed:

1. A headband must be worn for 48 hours, to avoid the swelling of the head.
2. Avoid bending your head as much as possible, and keep a parallel line between your chin and the ground for three days, in order to avoid swelling in the areas of forehead and around the eyes.
3. Never wash your hair before the 72 hours period after the operation is over.

16. It is also preferred to have some vitamins that help enhance the growth of follicles.

Hair transplantation process goes through several stages:

First Stage: The density of the donor area, the area to be implanted and the number of follicles to be picked out are determined. The front line is drawn.

Second Stage: The patient undergoes the necessary tests and checkups, which are blood tests and some dermatology examinations.

Third Stage: In this stage, the entire hair is shaved, in the case of hair transplantation was to be conducted with (FUE) technique. If the DHI technique or Robot technique was to be used, then only the donor area is shaved, in order to facilitate the process of picking the follicles out. The patient then is anesthetized with a local anesthesia.
