May I see some examples of a 500 graft FUE hair transplant?

The price of Hair Transplant operation depends on several factors such as the difficulty of your case and your request for your operation area.
In my practice, prices for Hair Transplant operation reaches from 2500 Euro up to 4500 Euro range, and it also includes the travel package such as accommodation, local transfers, and language assistance. If you want to learn more you can click the link below.

It is always a good idea to discuss your issues with your doctor.  If you're more comfortable with less grafts you can always add more at another date.  It's easy to add.  Impossible to subtract.

A great first step would be an online consultation. Often you can submit photos to top hair restoration surgeons for a complimentary evaluation and assessment. This should help lead you in the right direction. Having multiple consultations with different doctors will let you know your best options. Ask to see results from your prospective hair restoration clinics. 

It is better to see your photos  in order to understand the problem you have, treatment methods and/or estimate how much graft do we need to cover area .

This is a very difficult question to answer without seeing the area you want addressed. Also the thickness of your hair will produce a different results if it were fine vs coarse. A visit face-to-face with a doctor is the best way to address your concerns.  We hold open house events once a month where patients come in so people like you can see the results they get.
