Shock loss is one of the most alarming experiences for patients in the weeks following a FUE hair transplant. After what appears to be a successful procedure, existing native hair around the recipient zone begins to fall out. For many patients, this feels like the transplant has gone wrong. In the vast majority of cases, it has not.
Shock loss — also called effluvium — occurs because the trauma of surgery temporarily disrupts the growth cycle of hair follicles in and around the treated area. The follicles do not die; they enter a resting phase called telogen, causing the hair shaft to shed. The follicle then re-enters the growth phase over the following weeks and months.
It typically begins between two and eight weeks post-surgery and can affect both transplanted and existing native hair. The transplanted hairs shedding at this stage are not lost — only the hair shaft falls. The follicle beneath remains alive and will regrow.
Shock loss is more common in patients who had significant existing miniaturised hair in the recipient area, or in those who did not continue with medical therapy such as finasteride around the time of surgery.
Recovery from shock loss is gradual. Most patients see regrowth beginning at three to four months, with the final density becoming apparent at twelve months. Patience is essential — this is a normal part of the process, not a complication.
