The most common hair transplant side effects are temporary and minor: swelling of the forehead, mild pain or tenderness, scalp numbness, redness, scabbing around the grafts, and short-term shock loss of transplanted or surrounding hair. Serious complications such as infection or noticeable scarring are uncommon when an experienced surgical team works in a sterile clinical setting. Most effects settle within days to a few weeks.<\/p>\n
A hair transplant is a minor surgical procedure, so some short-lived side effects are normal as the scalp heals. They are usually mild and resolve on their own without intervention. Knowing what to expect makes the recovery far less worrying.<\/p>\n
The most frequently reported effects include:<\/p>\n
These are part of normal wound healing rather than signs that something has gone wrong. Following your clinic’s aftercare instructions keeps them to a minimum.<\/p>\n
Shock loss (telogen effluvium) is the temporary shedding of transplanted hairs \u2014 and sometimes nearby native hairs \u2014 in the weeks after surgery. It can be alarming because the scalp may look thinner before it looks fuller, but it is almost always temporary. The transplanted follicles remain in place beneath the surface and re-enter their growth cycle.<\/p>\n
New growth typically begins around three to four months, with most of the result visible by 9\u201312 months. Shock loss of existing hair usually recovers as well. It is not a sign of failure; it is an expected phase of the timeline. Our week-by-week recovery guide<\/a> sets out exactly what each stage looks like.<\/p>\n The two main techniques carry different scarring profiles. FUE (follicular unit extraction) harvests individual follicles, leaving tiny dot scars that are difficult to see even with short hair. FUT (follicular unit transplantation) removes a strip of scalp, leaving a single linear scar that can be concealed by surrounding hair.<\/p>\nHow does FUE compare with FUT for scarring?<\/h2>\n
