Crusts, scabs and swelling after transplantation
Swelling of the forehead and eyes, scabs at the implantation sites, itching in the donor area – what's normal, what's a warning sign, and what you should (and shouldn't) do.
What you will see on the scalp after the surgery
Three phenomena occur regularly — none are a problem, all follow a fixed timeline:
- Crusts at the implantation sites — Day 2 to Day 14
- Swelling on the forehead and occasionally eyelids — Day 2 to Day 5
- Redness in the recipient area and donor area — Day 1 to Week 6
Crusts and Scabs
Why do crusts form?
Every micro-injury to the skin forms a protective scab from clotted serum and blood. In FUE, a puncture wound occurs per graft in the recipient and donor area — resulting in many small crusts. They protect the healing skin from dehydration and infection.
Course
- Day 1–2: red dots, beginning scabbing
- Day 3–7: full crust formation
- Day 7–14: slow dissolution through gentle washing and natural skin renewal
- From Day 14: crusts mostly fallen off, slight redness remains for weeks
What to do
- Apply care oil or prescribed spray daily, softens the crusts
- Wash gently according to practice instructions — see Washing hair after HT
- Let crusts fall off on their own — the body detaches them between Day 10 and 21
What NOT to do
- Scratch, pick, or brush off crusts — endangers grafts, can cause scarring or loss
- Hot shower directly on the crusts — promotes swelling
- Apply alcohol or disinfectant to the crusts
Swelling
Why does it swell?
Local anesthesia is injected with a solution into the surgical area. This fluid distributes downwards in the first 48–72 hours — typically to the forehead due to gravity and occasionally to the eyelids. This often causes a moment of shock visually, but is medically harmless.
Typical course
- Day 1: usually no visible swelling yet
- Day 2: beginning forehead swelling
- Day 3: maximum reached, can extend to the eyelids
- Day 4–5: subsiding
- Day 6–7: usually completely gone
What reduces swelling
- Elevate head — even at night with two pillows at a 30–45° angle
- Forehead sweatband for the first 3 days — drains fluid away from the recipient area
- Cooling on forehead and cheeks — never directly on the recipient area! Cool packs wrapped in cloths for 10 minutes every 2 hours
- Low-salt diet for the first 3 days
- Drink plenty of water — paradoxical, but helps
- No alcohol, no sauna, no physical exertion
What increases swelling
- Lying position without head elevation
- Alcohol, salt, greasy food
- Physical exertion, straining, bending
- Heat (hot shower, hairdryer, sauna)
- Aspirin and other blood-thinning medications
Redness
In the recipient area
The micro-channels appear as pinkish-red dots. Course:
- Day 1–14: significant redness
- Week 2–4: gradual lightening
- Week 4–8: normal skin color in most cases
- For lighter skin: redness may remain slightly visible until month 3
In the donor area
Less pronounced here, due to smaller puncture wounds. Usually no longer visible after week 2 — especially if the hair grows a little longer.
What helps
- Sun protection (sun hat, later SPF 50)
- No irritating styling products or dyes in the first 4 weeks
- Patience — microcirculation normalizes gradually
Itching
Common from week 2 — a sign of healing. Still annoying.
- Allowed: light tapping with fingertips, cool compress
- Avoid: scratching, brushing, mechanical rubbing
- For severe itching: antihistamine after consulting the practice
- For burning, sudden stinging, combined with redness: possible infection — contact the practice
Warning signs — when to contact the practice
- Severe pain after Day 5
- Swelling pain instead of decreasing
- Purulent discharge from the implantations or donor area
- Fever > 38.5°C
- Spreading redness beyond the surgical areas
- Severe, unusual swelling after Day 5
- Bleeding that does not stop after 10 minutes of pressure
- Loss of sensation beyond normal numbness
Frequently Asked Questions
When will the crusts be completely gone?
Typically, most fall off between Day 10 and Day 14. Individual stubborn crusts may remain until Day 21. By week 3, the scalp should be largely crust-free.
How long will I have a red forehead?
Forehead swelling completely subsides between Day 5 and 7. Slight redness in the recipient area can remain for several weeks — less visible with darker skin, up to 2–3 months with very light skin.
Are small crusts in the donor area also normal?
Yes, puncture crusts also form there at the extraction sites. They often fall off even earlier because the donor area heals differently. Some patients barely notice them.
What if a crust comes off with a graft?
Can happen in rare cases, especially with premature mechanical rubbing. If you see a single graft on a fallen crust — no drama, the loss of a single graft is irrelevant to the overall result. If there are several or it bleeds: contact the practice.
When is swelling dangerous?
If it increases instead of decreases after Day 5, is severely pronounced on one side, is combined with pain or fever, or extends far beyond the surgical area. In such cases, a medical evaluation is essential.
Do Bromelain or Arnica help with swelling?
There are initial indications of a slight decongestant effect. Before taking them, please clarify with the practice — Arnica can interact with blood thinners, Bromelain with antibiotics.
