Dear houssam23,Thank you for posting your question. It is possible to make a straight hairline into a more natural one. Hair restoration requires a considerable amount of artistic talent on the part of the surgeon. Very, very few physicians have significant training/schooling in the fine arts, and as a result, there are many transplanted hairlines out there that are too straight, in the wrong place, or simply unnatural in appearance. Repairing your work can be done, but it depends on which method of hair restoration you had, and how long ago the procedure was performed. If you’re not happy with the hairline that the physician placed on your scalp the first time, it’s not so likely that you will be happy with it on a second go-around. I would look for a physician who has dedicated his career and practice to the field of hair restoration surgery, with a proven track record of success in creating natural hairlines. More than one consultation may be necessary. As we say in this field, “the good thing about the results from a hair transplant surgery is that they are permanent. The bad thing about the results from a hair transplant surgery is that they are permanent.” So, consider your options carefully before proceeding. I hope this information is helpful to you.
