For the first two days after a hair transplant, pulling on a transplanted hair reliably removes the graft with it. By day six that is no longer true, and by day nine the grafts are no longer at risk of being dislodged at all. That finding, from a study in which grafts were deliberately pulled at intervals after surgery, is the reason behind almost every instruction you are given: no rubbing, no towel, no hat, no gym, no sea. Once you know the timeline, the rules stop being arbitrary.
Small crusts form over each graft in the first days. In the same study, pulling on an adherent scab removed the graft through day five — meaning a crust that is stuck to a graft is a handle attached to it. This is why the washing routine exists at all: its entire purpose is to soften and lift those crusts gently, so they come away on their own instead of taking grafts with them.
Crusts normally shed between about day four and day fourteen. Do not help them along. Picking a crust off on day six is the single most common way people lose grafts they have paid for, and it does not look like damage at the time — the graft comes away invisibly inside the crust.
Sleep semi-upright, no washing, no hat. The donor bandage stays on if the clinic put one there. Some swelling of the forehead is normal and usually appears on day two or three rather than the first night.
Most clinics perform this themselves, and this is why you should not fly home before it. They apply a lotion or foam to soften the crusts, leave it 20–45 minutes, then rinse with low-pressure lukewarm water. Watch what they do closely; you are about to repeat it alone for two weeks.
Apply the lotion by dabbing, not rubbing. Leave it to soften the crusts. Lather the shampoo in your palms first, then place the foam on the recipient area — never rub. Rinse by pouring water from a cup or with a very weak shower stream held well away. The donor area can be washed normally with fingertips from about day three; it is the recipient area that must not be touched.
Once the grafts are secure, light circular massage with the pads of your fingers helps the remaining crusts come away. Still no scrubbing, no nails, no hot water. If crusts remain after day fourteen, keep softening them daily rather than picking.
Normal shampoo, normal pressure, normal drying. Grafts are anchored. What comes next is not a wound-care problem but a growth timeline: shedding of the transplanted hairs between weeks two and six is expected and is not graft failure.
Sleep on your back, semi-upright at about 45 degrees, for the first three to five nights. Two or three pillows or a travel neck pillow will do it. There are two reasons, and only one of them is about the grafts: elevation reduces the forehead swelling that peaks around day two or three, and lying flat on your side risks pressing the recipient area into the pillow while you are asleep and cannot feel it.
The donor area is a fresh wound at the back of your head, so a neck pillow that supports the neck without touching the occipital area is more comfortable than an ordinary pillow. Put a dark towel over the pillowcase for the first few nights; a small amount of oozing is normal and stains.
Most people can return to normal sleeping positions after the first week and certainly by day ten, when the grafts are secure. If you know you roll onto your front in your sleep, keep the semi-upright arrangement for the full ten days.
| Activity | Earliest | Why that long | Your surgeon may say otherwise |
|---|---|---|---|
| Wash your own hair (gently) | Day 1–2, as instructed | The wash softens crusts. Skipping it makes crusts adhere harder, and an adherent crust removes the graft with it. | Follow your clinic's written instruction if it differs. |
| Touch the recipient area with fingertips | Day 10 | Grafts are no longer dislodged by pulling from day 9; day 10 leaves a margin. | Follow your clinic's written instruction if it differs. |
| Return to office work | Day 3–5 | Nothing medical stops you sooner. The limit is appearance and the risk of something brushing your head. | Follow your clinic's written instruction if it differs. |
| Wear a loose hat | Day 10 | Anything resting on the recipient area before the grafts anchor can pull one out when it is removed. | Follow your clinic's written instruction if it differs. |
| Light walking | Immediately | Encouraged. Movement is good; sweat and impact are the problem, not walking. | Follow your clinic's written instruction if it differs. |
| Gym, running, cycling | Day 14 | Heavy sweating softens crusts and raises infection risk, and raised blood pressure can restart bleeding in the donor area. | Your clinic may extend this. Never shorten it without asking. |
| Heavy lifting, contact sport | Week 4 | Straining raises intracranial and scalp pressure; contact risks direct trauma to a healing donor area. | Follow your clinic's written instruction if it differs. |
| Swimming pool | Week 4 | Chlorine irritates healing skin and the pool is a bacterial exposure while the donor wounds are still closing. | Follow your clinic's written instruction if it differs. |
| Sea | Week 4 | Salt water plus sun plus unpredictable impact. Later than a pool if the water is not clean. | Follow your clinic's written instruction if it differs. |
| Direct sun on the scalp | Week 2 minimum, hat until week 4 | New skin burns easily and the area is numb, so you will not feel it. Sunburn over fresh grafts can damage them. | Follow your clinic's written instruction if it differs. |
| Sauna, hammam, hot tub | Week 4 | Heat, sweat and bacteria at once — the worst combination for a healing scalp. | Follow your clinic's written instruction if it differs. |
| Alcohol | Day 5–7 | It thins the blood and dehydrates; both work against early graft survival. | Follow your clinic's written instruction if it differs. |
| Smoking | Avoid entirely for 2 weeks | Nicotine constricts the small vessels that must grow into the grafts. This is the aftercare rule most likely to change your result. | Follow your clinic's written instruction if it differs. |
| Hair dye | Week 4–6 | Chemical irritation of healing skin, and the new hairs are fragile. | Follow your clinic's written instruction if it differs. |
| Cut the transplanted hair | Month 6, scissors only | Clippers on the recipient area before six months risk disturbing hairs that are still establishing. The donor area can be clipped from about week 3. | Follow your clinic's written instruction if it differs. |
| Fly | Day 1 | Cabin pressure does not affect grafts. Avoid the headrest and get up regularly. | Follow your clinic's written instruction if it differs. |

Expect these, and do not panic: swelling of the forehead and sometimes around the eyes on days two to four; numbness of the scalp for weeks or occasionally months; itching from day five as healing starts; redness of the recipient area that fades over several weeks and takes longer on pale skin; and shedding of the transplanted hairs between weeks two and six. That last one frightens people badly. It is the hair shaft falling out while the follicle stays; regrowth starts around month three.
Contact the clinic if you get spreading redness with pain and heat rather than fading redness, pus from more than an isolated spot, a fever, bleeding that does not stop with ten minutes of light pressure, or swelling that gets worse after day four instead of better. Small pimple-like spots in the recipient area around weeks two to six are usually folliculitis around an ingrown hair — common, treatable, and worth showing a doctor if there are many.
It does not tell you when your hair will look finished. That is a growth timeline, not an aftercare one: most of the visible result arrives between months six and twelve, and the final judgement belongs at twelve to eighteen months.
It also is not a substitute for your clinic's instructions or for a doctor who can see your scalp. Every timing here is the general case, and the general case is not a diagnosis.
Normal washing — ordinary shampoo, ordinary water pressure, fingertips on the recipient area — from about day fifteen. Before that you wash daily but with a specific technique: soften the crusts with lotion, dab rather than rub, and rinse by pouring rather than under a shower stream.
A study that pulled grafts at intervals after surgery found that for the first two days pulling a hair always removed the graft, by day six it no longer did, and at nine days grafts were no longer at risk of being dislodged. Crusts extend that window, because pulling an adherent scab removed the graft through day five.
On your back, semi-upright at roughly 45 degrees, for the first three to five nights. Elevation reduces the forehead swelling that peaks around day two or three, and sleeping on your back keeps the recipient area off the pillow while you cannot feel it. Most people return to normal positions after day ten.
Day fourteen for ordinary training, week four for heavy lifting and contact sport. Sweat softens crusts and raises infection risk, and raised blood pressure can restart donor-area bleeding. Walking is fine immediately.
About four weeks for both. Chlorine irritates healing skin, sea water adds salt and sun, and both are bacterial exposure while the donor wounds are still closing. If the water is not obviously clean, wait longer.
Almost certainly not. Shedding of the transplanted hairs between weeks two and six is expected. The hair shaft falls out while the follicle stays in place, and regrowth begins around month three. What would be abnormal is losing crusts with visible graft material in the first week.
The donor area can be clipped from about week three. The transplanted area should be scissor-cut only until about month six; clippers before then risk disturbing hairs that are still establishing.
