Hair transplantation can be performed on any person with pattern hair loss, good donor area, good general health and reasonable expectations.
The factors that affect case selection are as follows:
1) Age: Patients between the age of 18 and 75 can do FUE. Young patients whose early alopecia is still evolving should not be taken up for hair transplantation. This is mainly because he will be in the process of losing the hairs and if after implantation he loses his existing hairs it will give him a weird look. So it will be best suited to patients in the age group 23 –55 years.
2) Sex: Both females and males can do FUE , but as the males have more localization of 5 alpha reductase activity for hormone Dihydro–testosterone, males will have a better result than females.
3) Grade: According to Norwood –Hamilton scale for classification of Androgenetic Alopecia, persons from Grade 2 to Grade 5 can undergo FUE. If the patient belongs to grade 6 and 7, usually the donor area density is very low and the existing donor hair resource will not be sufficient to cover the entire bald zone. Hair transplant can be done in area 2, 3 and 4 which will improve your looks considerably.
4) In clinical conditions that forms scarring on the scalp skin like Discoid Lupus Erythematosus (DLE), Lichen planus, Folliculitis decalvans, in extreme burns etc. due to formation of fibrous tissue, hair transplantation is not possible.
5) In patients having Alopecia Areata hair transplantation is not the right method to treat baldness.
6)Patients with significant systemic health problems:
Those patient who are having blood pressure above 140/90 mm of Hg should not be taken for Hair Transplant until his / her BP reduces to normal range. Blood sugar should be below 130 mg/dl. If the patient is under medication for the above condition Hair Transplant can be done only with a physical fitness certificate from a MD Physician. The patient’s CT, BT, PT, INR etc, should be in normal range. If patient is having any bleeding disorders, doing hair transplantation is not advisable.
