Scabs form two to three days after a hair transplant and usually clear within seven to ten days when the scalp is washed properly. The part that matters most: a 2006 study measured how firmly grafts sit in the scalp and found that pulling on an adherent scab could dislodge a graft up to day eight. From day nine onwards it could not.1 That is why nobody should pick.
Almost everyone who has had a transplant in Istanbul or anywhere else spends the second week staring at their scalp in the mirror. The crusts look alarming, they are the first visible thing that changes, and the internet is full of people telling you to leave them alone without explaining why. Here is the actual reason, with the timeline and the evidence behind it.
Why scabs form in the first place
Every implanted follicular unit sits in a tiny incision. In the hours after surgery a small amount of blood and tissue fluid collects around each one and dries. By day two or three that dried fluid has become a crust sitting on and around the graft.2
The crusts are part of normal healing, not a sign that something went wrong. What matters is how they come off. A crust that softens and lifts on its own takes nothing with it. A crust that is pulled off early can take the graft with it, because in the first week the graft is not yet anchored.
The timeline, day by day
| Period | What is happening | What you do |
|---|---|---|
| Day 0 to 2 | Blood and fluid dry around each graft. Swelling often peaks around day three. | Follow your clinic's instructions exactly. Sleep elevated. No washing unless your surgeon said otherwise. |
| Day 2 to 3 | Crusts have formed and are clearly visible. | Most clinics start gentle washing in this window.2 |
| Day 4 to 8 | Crusts begin to soften with each wash. Grafts are still vulnerable to being pulled out with an adherent scab.1 | Wash gently, let lather sit, rinse by pouring. No rubbing, no fingernails. |
| Day 9 to 10 | Grafts are anchored. Most crusts have gone or are about to.1 | You can be slightly firmer, but still no picking. |
| Day 10 to 14 | The recipient area usually looks clear. Some redness may remain. | Return to your clinic's normal routine. |
If crusts are still stubbornly attached after day fourteen, that is usually a washing problem rather than a healing problem. Speak to your clinic before trying anything more aggressive.
Scabs are one stage of a longer process. If you want the whole picture, from the swelling on day one to the final result at twelve months, we have set it out here: the hair transplant recovery timeline, week by week.
If your own hair around the grafts starts shedding at the same time, that is a different thing again: shock loss after a hair transplant.
And if your forehead and eyelids have swollen in the first few days, that has its own page: hair transplant swelling.
The day nine rule
The same study found that pulling on a hair alone stopped dislodging grafts a little earlier, from around day six. The scab is the riskier one, because it is stuck to the skin around the graft as well as to the graft itself.
This is the single most useful number in post-transplant care, and it is why every clinic tells you not to pick. It is not superstition. It has been measured.
Washing: the part people get wrong
The instinct after surgery is to touch the scalp as little as possible. That instinct is wrong, and the evidence is fairly clear about it.
A 2026 review of complications after FUE reports that gentle cleansing started within 24 to 72 hours supports faster re-epithelialisation and reduces bacterial colonisation. The same review notes recipient-site folliculitis in around 12.1% of cases in a large multicentre dataset, and identifies delayed washing beyond three days as an independent risk factor for the more severe cases.2
In other words: washing too little is a real risk, and washing roughly is a different real risk. The target is frequent and gentle.
What gentle actually means
- Lather the shampoo in your hands first. Never squeeze it directly onto the grafts.
- Place the lather on the scalp and let it sit for a few minutes so it softens the crusts. Do not scrub.
- Rinse by pouring lukewarm water from a cup. Direct shower pressure on the recipient area is too strong in the first week.
- Pat dry with a clean towel, or let the scalp air dry. No rubbing.
- Repeat daily, or as often as your clinic told you.
What the research says about shampoos
There is one recent study worth knowing about, and it is worth being precise about what it did and did not show.
In 2026, a team publishing in Frontiers in Medicine ran a multicentre pilot in which 21 men used a shampoo containing 2% salicylic acid with piroctone olamine twice daily for ten days, starting 48 to 72 hours after FUE. Mean scab severity fell from 2.67 to 1.76, and 76.2% of patients agreed the shampoo reduced their scabs. No adverse events were recorded.3
This was a single-arm pilot with 21 patients and no control group. The authors say so themselves: normal healing over ten days, rather than the shampoo, may explain part of the improvement. It is a promising signal, not proof. Do not change what your surgeon told you to use on the basis of one pilot study, and never apply a keratolytic or anti-dandruff product to fresh grafts without asking your clinic first.
What it does tell you is that the ingredient thinking is reasonable: a mild, sulphate-free cleanser that softens crusts is doing useful work in the first two weeks. The rest is technique and patience.
Five things not to do
- Do not pick, scratch or rub crusts off. Before day nine this is the one action with a measured risk of losing grafts.1
- Do not use hot water. Lukewarm only. Heat increases swelling and makes the scalp itch more.
- Do not put the shower head straight on the recipient area in the first week.
- Do not wear a tight hat until your clinic clears it. A tight band can catch crusts.
- Do not switch to a strong anti-dandruff or exfoliating shampoo on your own. Those are formulated for intact skin, not for a healing scalp.
When to contact your clinic
Crusting is normal. These are not. Contact the clinic that performed your surgery if you see:
- Spreading redness, heat or swelling after day four, rather than settling
- Pus, or crusts that keep reforming in the same spot
- Fever
- Pain that is getting worse rather than better
- Crusts that are still firmly attached after two weeks of correct washing
Most Istanbul clinics, including the ones our UK customers come through, keep a WhatsApp line open for exactly this. Use it. A photograph costs you nothing.
If you would rather choose for yourself, we have written a plain guide to what the published trials tested and what to look for on a label: what shampoo after a hair transplant.
Shampoos for the first weeks
RISE+ Post-Transplant Repair Shampoo, 300 mlSulphate-free and pH balanced, with panthenol, allantoin, biotin and Procapil. Made for the weeks after surgery.£40.00
HairMD Clinical Hair Repair Shampoo, 250 mlContains piroctone olamine, panthenol, allantoin and aloe. Gentle daily cleansing for a sensitive scalp.£45.00
Both are cosmetic products for gentle cleansing. Neither treats a medical condition, and neither replaces your surgeon's instructions. If your clinic gave you a specific shampoo for the first fortnight, use theirs. You can see the full range in our hair transplant aftercare sets, and the month-by-month picture in our complete aftercare guide.
Frequently asked questions
How long do hair transplant scabs last?
What happens if a scab comes off with a hair attached?
Can I speed up scab removal?
Is it normal for the scabs to itch?
When can I use a normal shampoo again?
- Scabs appear on day two or three and usually clear by day seven to ten.
- Grafts can be dislodged by pulling an adherent scab up to day eight. From day nine they cannot.1
- Gentle washing started within 24 to 72 hours reduces infection risk. Washing later than three days is linked to more severe folliculitis.2
- Lather in your hands, let it sit, rinse by pouring, pat dry.
- Anything hot, tight, abrasive or exfoliating waits until your clinic says so.
