How Much Hair is Growing in by 3 Months After a Hair Transplant?

At 3 months post-transplant, very little (if any) transplanted hair has started to grow.  the transplanted hair shafts will generally fall out within the first few weeks or months after surgery and then start to re-grow around month 3-4.
By 6 months, patients should be starting to see some growth, but the hair shafts will generally be fine and not very robust.  As time progresses, the hairs should increase in caliber.  They will become longer, more coarse, and this results in increased hair "mass" or density (the look of a fuller head of hair).  The final result cannot be judged until the 12-18 month time frame.
All the best,

Hi and thanks for your question.  Transplanted hair starts to grow typically at 3 months.  Not all of the follicles start at this time.  Full growth and final results are at about 1 year.
