Hair Transplant Risks: Side Effects, Scarring and Aftercare

Understand expected changes after hair transplant surgery, risks to the donor and recipient areas, and symptoms that need prompt medical advice.

Hair transplantation involves surgery in two places. The donor area is where hair is collected. The recipient area is where the grafts are placed. Both need aftercare, and a problem in one area can look different from a problem in the other.

What can happen during early healing?

Tightness, scalp swelling, small scabs and some discomfort can occur after surgery. Transplanted hairs may shed before new growth appears. Ask the surgical team what they expect for your procedure and when they want to examine you. Increasing pain, spreading redness, pus, fever or bleeding that does not settle warrants prompt clinical advice.

What are the longer-term risks?

Hair collection leaves scars. Follicular unit extraction usually leaves many small marks, while strip surgery leaves a linear scar. How visible these appear depends partly on healing, the distribution of extraction and how short you wear your hair. Poor graft growth, an unnatural direction or ongoing loss of surrounding hair can affect the final appearance.

What should the surgeon discuss before consent?

Ask about donor reserves, previous scalp surgery, medicines that affect bleeding and any history of difficult wound healing. Have the surgeon explain how your plan accounts for future thinning. Request written aftercare, the number to call outside clinic hours and the arrangements for a complication or a result that falls short of the agreed plan.
