When will my hair start to thicken after a hair transplant?

You
have nearly reached your final result. Some people may need few more months in
order to see it. Your hair normally might be at the same thickness as the donor
area. Did your donor area have thick hair? If you are not happy with the hair
density you probably might consider of a second hair transplantation stage. I
would advise you to wait for another two or three months and then decide what
you desire to do.

The hair is growing up to 12-18 month, you should wait few months more to see the final result.

Generally hair starts
to grow within 2-3 months after a hair transplant and restore its thickness
within 6-12 months. The density depends
on the thickness of your donor hair prior to the hair transplantation. If you
desire more fullness after 12 months, consider doing a follow up hair
transplantation procedure. You should
also consult your transplant physician about the possible need to use FDA
approved hair loss medications such as topical minoxidil and finastride. Read

It can take 6 to 12 months to see the results after a hair transplant surgery.  However everyone is different and if you think your results are not progressing it is always a good idea to follow up with your doctor.

After transplantation, the transplanted hairs often shed at a month, then begin to regrow a new hair at 3 months.  That process gains speed though months 6 an 9, so you're still in the midst of regrowth.  Don't pass judgement on your surgery until you are a year out.  If you have concerns, certainly go back to your hair transplant surgeon and be re-evaluated.  Good luck!

Transplanted hair starts growing in about 2-3 months after a hair transplant and by month 6 all grafts have grown hair in most people.  The final results could be seen in about 6-10 months when your hair is longer and the newly transplanted hairs are thicker.  At that point you can see full results.  Based on your hair characteristics and styling you may see full results at 10-12 months after your procedure. Occasionally patients may have delayed growth at 6 months follow up but most those patients show full results by month 12.

At 7 months, most people see most of the hair growing to a length of about 1 inch. Wait another 2-3 months and if you don't see what you expect, return to your doctor and ask your doctor if he/she thinks that all of the hairs have grown.
