Causes of hair loss
There are many reasons for the loss of hair in humans. Permanent baldness is the major cause of hair loss in men due to genetic factors. The other reasons for hair loss are below:

Certain hairstyles and treatments
There are basically two types of hair transplants procedures performed by surgeons. It depends on the need of coverage on the scalp. Its types include-
Slit graft- It contain 4-10 hair in each graft
Micrografts- it contain 1-2 hairs in each graft
Surgeon starts the procedure of hair transplant by cleaning the scalp. He uses a small needle to give local anesthesia in order to numb the bald area of the head. He can use two main techniques namely FUT (Follicular Unit Transplantation) and FUE (Follicular Unit Extraction).
Follicular unit transplantation or strip method-
A thin strip of scalp is extracted from the back of the scalp with the help of scalpel. It usually contains 1 to 4 hairs.
Tiny cuts are made on the site of surgery
This strip is placed on the tiny cuts.
It is then closed with stitches.
Follicular Unit Extraction (FUE)
The back of the scalp is shaved and surgeon removes the hair follicles one by one.
It heals leaving small dots.
Then, the area to be grafted with hair is shaved and holes are made on this area.
The hair grafts are placed with the help of scalpel or needle.
Both the process may take 4-8 hours. The stitches are removed in 10 days following the surgery. The patient may require three to four sessions to have the desired dense of hair on the head. Gaps are maintained between the sessions for proper healing of the transplants. Pain medicines, antibiotics and anti-inflammatory medicines are prescribed to avoid pain, infection and inflammation after the surgery.
Most people return in few days after the surgery. Normally, grated hairs fall down in two to three weeks after the surgery making way for the new hair to grow. New hair may appear in 8-12 months after the surgery. Most people experience 60 % of hair growth in6 to 9 months. In some cases, hair growth medicines such as minoxidil (Rogaine) or Finasteride are given to have better results.
Risks and Side effects/complications
The side effects for hair transplantation are not intense and go in few weeks. These include bleeding, infection, swelling in the scalp, bruising around the eyes, crust on the scalp, numbness or lack of sensation, itching or numbness on the transplanted areas.
the new hair continue to grow on the transplanted areas of the scalp. Its density depends on the laxity or looseness of the scalp, hair quality, hair curl and density of the follicles.
