After 7 month fue can I still wait for the growth of transplanted hair?

It can take 6 to 12 months after surgery to see results.  If you are concerned it is best to contact your doctor

7 months past FUE you still have a significant amount of time left before reaching the final growth state near 12 months. It is very possible/likely that in these coming months you'll see some improvements with the transplant growth.

The final results of a hair transplant procedure will become more evident after 12 months. 7 months is far too early to judge the final results. Your hair will continue to grow and thicken during this period. Furthermore, it is recommended that you take Finasteride for maximum effectiveness. A positive regrowth rate along with a natural appearance is the most sought after result when evaluating the success of a hair transplant.

Transplanted hairs start to visibly regrow between months 4-6. At month 6-9, a patient may expect to see growth for  80% of the transplants. Again, due to the random cycle of hair growth, not all grafts will start growing at the same time. Initially, the hair my be thinner and finer. It will gain length and density as it matures. Full growth from the transplants is usually achieved at 12 months. All the best

You should be seeing a majority of your transplanted hair growth by now. But you will still most likely see new hair growth continue for the next 4+ months. As the hairs do continue to grow as well you will hopefully see some good density. If you have any questions or concerns it never hurts to follow up with your hair transplant doctor. 

By the 8th month I tell my patients that they can expect 80% of the growth and 95% in 12 months
