The first seventy-two hours decide more than the first month
Grafts are physically vulnerable until they establish blood supply, which takes roughly three days. During that window every practical instruction matters: sleeping at an incline, avoiding any pressure or friction on the recipient area, not scratching however much it itches, and keeping the head out of direct sun. Swelling across the forehead typically peaks on day two or three and then settles. Most complaints we hear about disappointing results trace back to this period rather than to the surgery itself, which is why clinics keep you in the city for the first wash.
Shedding is expected, and knowing that saves a panic
Between weeks two and six most of the transplanted hairs fall out. The follicle stays; only the shaft is shed as it enters a resting phase. Patients who were not warned about this stage regularly assume the operation has failed and start writing to the clinic in week four. Nothing meaningful can be judged at that point. New growth begins around month three to four, thickens noticeably between months six and eight, and the final texture and density settle between twelve and eighteen months, later on the crown than on the hairline.
Returning to work, exercise and daylight
Desk work is realistic from day four or five, though redness in the recipient area is usually visible for one to three weeks depending on skin tone and how the channels were opened. Light walking is fine immediately; sweating, gym work and anything that raises blood pressure should wait two to three weeks. Swimming pools and the sea wait a month. Direct sun on the recipient area should be avoided for at least four weeks and then managed with a loose hat rather than sunscreen on fresh scalp for a while longer.
What follow-up should look like from a clinic worth its fee
A serious clinic contacts you at the first wash, at month one, month six and month twelve, and asks for photographs each time. That schedule is not customer service; it is how the clinic learns whether its own planning worked, and its absence is a signal. Keep your own photographs on the same schedule in identical lighting, because a comparison between month zero and month twelve is the only fair way to assess the result, and it is also the evidence you would need if you ever invoke a graft guarantee.
