There are six main characteristics that will determine your suitability for a hair transplant procedure:
Extent of hair loss
Normally, young patients between the ages of 18 and 25 are not the best candidates. At this age, any existing hair loss is likely to continue, affecting the long-term results of any procedure. Active hair loss at this stage can be best treated by medications.
Gender will affect hair loss, both in pattern and appearance. Generally, men will have localized areas of thinning or complete baldness, while substantial hair remains elsewhere. Women, conversely, will usually have generalized thinning over the complete head. This difference in how the hair is lost tends to make men better candidates for transplants in general.
The extent of your hair loss will also determine whether you have viable donor areas. If your active hair loss has stopped, your transplant surgeon will also have a better chance of placing hair grafts for the best result. Look for an experienced surgeon to evaluate your hair. In the Toronto area, the SureHair clinics are one possible option for good, qualified hair transplant specialists.
Beyond your level of hair loss, your hair type will actually affect whether you are a candidate for hair transplantation. If your hair is thick and coarse, it will provide more coverage than fine hair. Wavy hair is another advantage, as it also provides more coverage than straight hair.
The actual density of hair on your head is key to whether you have enough hair for donation. The more hair that you have remaining on your head once your hair loss has stabilized, the better the chances that you will qualify as a good candidate for a hair transplant.
Your racial background will also play a part in your evaluation. People from Asia typically have very straight hair and fewer hair follicles. Patients with this genetic background will need to ensure that they consult with a surgeon who is familiar with their unique needs.
Individuals of African descent will usually have curly, coarse hair, which results in a much better cosmetic result. Further, darker skin tones will mean there is less contrast between the hair and the skin. One disadvantage for this racial type is that keloid scarring is a much bigger issue, which may mean that donor site scars are more noticeable.
Those of Caucasian descent will have the widest range of hair and skin types. Generally, those with coarse, dense, wavy hair and a skin tone close to their hair color, will have the best results.
Scalp laxity is the last major factor in your suitability for hair transplant. A qualified surgeon can tell you more about this, but the more lax your scalp, the more hair you can harvest for donation.
