Curly Hair and Eyelash Transplant?

The hair you describe, curly but not kinky, can be effectively used in eyelash transplants. However, the exact degree of curl needs to be evaluated, and then there is the issue- as with any eyelash transplant- of the patient being informed as to the risk of these procedures of the hairs growing in a difficult to control direction.

In the age of Latisse and other biologic eyelash growth stimulators, eyelash transplants are not the best choice for cosmetic enhancement. Latisse and similar products can acheive uniform, predictable growth of the lashes that a transplant cannot achieve.
Eyelash transplants can be a very natural, beautiful option. However, the risks and downsides need to be considered: long term trimming and curling is required (translation- higher maintanance), and irregular growth and scarring can occur as well. If your hair is wavy or curly, the transplanted lash will require more maintanance to create a natural lash curve (with trimming and curling).
Latisse and similar drugs cannot create lashes in post trauma situations where the lash follicles have been lost. In these cases, transplant is the only option.
If you're looking for a cosmetic improvement of your lashes, and you have not had trauma to your eyelids causing lash follicle loss, I would strongly recommend Latisse well before an eyelash transplant.
Hope this is helpful and best wishes to you!
