Thin growth after 7.5 months post FUE (Photo)

Although you will experience further growth and an increase in density over the next several months, it does appear that you are having good results in terms of regrowth from an FUE procedure at this time.  It is difficult to assess from the photos but the results of a transplant are highly dependent on the quality of your hair (whether you have naturally thick or fine hair) and the distribution of grafts in the recipient area.  That is, if many grafts were placed over a large area your density over a larger area will be sacrificed.  It is important that proper expectations were placed before your procedure in terms of the density that one can expect to have from a hair transplant.     

It can take six to twelve month after a hair transplant surgery to see results. So at seven months, it may be too early to judge.

It's hard to say based on just a picture but at 7.5 months your hair likely has significant growth still left to do. I would wait until 12 months before worrying, as that is when most doctors consider the hair to be fully grown. From there you can consult with your doctor if you are still unhappy with your progress.

It seems to be fine. Wait for your final result around 12 months, you'll experiment a good improvement. In your pre-photo (I assume that the photo in the left is the pre-op) you have a lot of thinning hair that will respond to medical hairloss treatment and improve your result.

Now you feel that the growth is thin, less full than you expected. You must go back to your doctor and have this conversation with your doctor. At 8 months you can expect to see 80% of the growth, another 20% in the next four months or so.

After hair transplant usually the hair shaft falls off and the follicles remain under the scalp. The new hair grows in gradually after three to four months and will continue to grow for up to 18 months after the surgery. At seven months you should expect about fifty percent growth.
