RO Most bleeding in a hair transplant happens during the operation, not after it. Once the procedure is over, bleeding is uncommon and usually self-limited. What is expected in the first 24 to 48 hours is mild oozing from the donor or recipient sites — pinkish fluid on the dressing or the pillow rather than flowing blood (Romera de Blas et al., Frontiers in Medicine, 2026).
If a point does bleed, the published management is simple: continuous pressure with sterile gauze for five to ten minutes, until it stops. Continuous is the operative word — lifting the gauze to check restarts the process each time. Pressure is applied to the bleeding point, never rubbed across the grafted area.
What raises the risk is largely decided before surgery, and patients routinely under-report the second half of this list:
| Category | Examples |
|---|---|
| Medical | Bleeding disorders, uncontrolled hypertension, cicatricial alopecia |
| Medication | Oral anticoagulants, antiplatelet agents, NSAIDs |
| Supplements and alcohol | Vitamin E, ginkgo biloba, ginseng, alcohol |
This is why a medication and supplement review before surgery is not a formality, and why blood pressure is controlled rather than noted.
What is not ordinary oozing: bleeding that is pulsatile, that continues after ten minutes of proper pressure, or swelling that expands and firms rather than settling. Those belong to the clinic the same day, not to the next scheduled contact.
