Is it possible to do a hair transplant over scar from nevus sebaceous removal on scalp? What is the approximate cost? (Photos)

The cost of hair transplant surgery differs from doctor to doctor / from clinic to clinic.  It is best you see different doctors for a consultation.  Surgery is possible to cover your scar.

Thank you for your question.  Your question is not an uncommon one but the answer is highly dependent upon your general medical health profile and a physical exam of the area.  It is definitely possible to successfully transplant hairs to camouflage the presence of a scar, but there are considerations such as blood flow and size and age of scar that are important to consider.  Scar reductions are also possible, but again depending upon the size of your scar and the amount of movement expected from adjacent tissues, closure can sometimes be difficult and it is critical that there is no tension on closure.  I would recommend scheduling a consultation with a board certified plastic surgeon who is well versed in these procedures.  Doing so would afford you the opportunity to discuss all of the options and treatments available to you in great detail after a thorough examination of the area in question.  I hope you find this helpful and I wish you the best.

I have had great success transplanting scalp scars, like the one in your picture. There are tricks to getting hair to grow and maximizing density in a scar. Firstly, scars can often be reduced surgically. This means a smaller transplant overall - or, maybe a transplant can be avoided. When the scar is excised, the closure must be tension free.  This is accomplished by wide undermining and release techniques. Unfortunately, scar excision seems to have left you with a bigger bald spot, which may happen in some circumstances.  In cases where scar excision is not possible, then you just try to maximize density with a hair transplant. One trick is to transplant with using DFU (double follicluar units) so there is twice as many hairs for each slit placed. Another trick is to use PRP (platelet rich plasma) to improve growth and vascularity in conjunction with a hair transplant, though this is not used in every situation. Overall, the cost varies greatly by surgeon, complexity, and geography.  In NYC, where I practice, the cost ranges from 5-15k though may be lower or higher depending on the case.  In cases where the patient has had poor results with other physicians or in cases of very large scars that cannot be surgically reduced, I may recommend a test-patch to see if the transplant will work in a small section of the scar. In this method, a small number of hairs are transplanted to see if the hairs will grow in the scar. If the transplant takes, then we can transplant the whole scar. If the test patch does not take, then we can revise our approach.  Hope this thorough answer gives you some clarity and direction. Best of luck.
