Quick Answer
PRP hair treatment aftercare protects the platelets your dermatologist just injected into your scalp, so it can take effect. Do not wash your hair for the first 24 hours. Avoid the gym and strenuous activity for 24 to 48 hours. Avoid hot showers, sauna, and direct sun on your scalp for about 3 days. Use paracetamol, not ibuprofen or aspirin, if you feel sore. Avoid hair colour and chemical treatments for 1 to 2 weeks. Mild soreness, redness, and swelling are normal and settle within 24 to 48 hours. Full results are visible over time, across several sessions.
Platelet-rich plasma therapy works by using concentrated factors from your own blood to stimulate scalp follicles. Proper PRP hair treatment aftercare determines how effectively the injected growth factors settle into the scalp tissue.
Taking care of your scalp post-treatment requires a clear balance between rest and gentle hygiene.
What happens in the first 24 to 48 hours after treatment?
After PRP, some soreness, tightness, mild swelling, and redness at the injection sites are normal. They usually settle within 24 to 48 hours. You should expect a tender or sore scalp, a mild headache, and a feeling of fullness. Some people also get slight redness and puffiness at the injection points, an occasional pinpoint bruise, or mild itching as it heals.
Infection or allergic reactions are quite rare. PRP uses your own blood, so the risk of rejection is low, and clinicians rarely document major complications like scarring, infection, or allergic reaction.
During the first 24 to 48 hours, you should rest and sleep as usual. A slightly raised pillow can ease the pressure. Drink enough water, and opt for paracetamol rather than ibuprofen or aspirin if you are sore.
Why do the first few days matter after PRP?
PRP is your own blood, spun in a centrifuge to concentrate its platelets. Once injected, those platelets release growth factors, proteins that tell nearby cells to grow, repair, and multiply. These growth factors signal your hair follicles through the same pathways that drive normal hair growth. The mild swelling in the first day or two is a normal local response to the injections, not a sign that anything is wrong.
You should avoid NSAID pain relievers such as ibuprofen, aspirin, and naproxen. While they inhibit COX enzymes, the main reason to avoid them is that systemic anti-inflammatories suppress the essential local inflammatory cascade and blunt initial growth factor release. Paracetamol acts through a different pathway without stopping this critical healing trigger.
Similarly, you should also avoid heavy sweat, heat, and sun. They irritate fresh injection points and lead to unwanted inflammation.

How many PRP sessions do you need before you see results?
Dermatologists usually recommend at least 3 sessions, about a month apart, with maintenance every 3 to 6 months.
Improvement starts around 3 months and is clearer by 6 months. The benefits fade without maintenance. Therefore, follow through on the follow-up sessions your clinic recommends.
The bottom line
Following a structured approach to PRP hair treatment aftercare protects your scalp while the growth factors work beneath the surface. While post-procedure care handles immediate recovery, lasting hair health depends on addressing internal factors like stress, gut balance, and nutrient absorption. Evaluating underlying systemic factors—such as nutritional deficiencies, thyroid function, or hormone levels helps ensure long-term hair health alongside your treatments.
Frequently asked questions
Can I wash my hair 12 hours after PRP?
It is better to wait the full 24 hours rather than washing at 12. Washing early can disturb the injection sites before they have settled.
Are 2 sessions of PRP enough for hair loss?
Usually not. Dermatologists generally recommend at least 3 sessions about a month apart, since results build gradually over several months.
How long does it take to recover from a PRP hair treatment?
Hair PRP recovery time is short. Soreness, redness, and mild swelling usually settle within 24 to 48 hours, and most people resume normal activity within 2 to 3 days.
How long should you avoid NSAIDs after PRP?
Skip NSAIDs like ibuprofen, aspirin, and naproxen around your session, both just before and for a few days after, and use paracetamol for soreness instead. They can blunt the platelet activity PRP relies on, so ask your clinic for the exact window.
What should you avoid right after PRP hair treatment?
Avoid NSAID painkillers, heavy sweat and the gym, hot showers, sauna, steam, and direct sun. Hold off on hair colour or chemical treatments for 1 to 2 weeks.
