PRP Hair Treatment Side Effects
PRP hair treatment side effects are generally minimal because it uses your own blood. Common effects include temporary redness, tenderness at injection sites, and mild swelling—all typically resolving within 24-48 hours. Serious side effects are rare when performed by qualified practitioners.
Common Side Effects (Normal)
Redness
Expect redness across the scalp for 24-48 hours. This is a normal response to injections and indicates your body's healing process has begun.
Tenderness
The scalp may feel tender or sensitive for 1-3 days. This is similar to mild sunburn sensation.
Mild Swelling
Some patients experience slight swelling, particularly on the forehead. This typically resolves within 24-48 hours.
Bruising
Small bruises at injection sites are possible but uncommon. They fade within a few days.
Headache
Some patients report mild headache on treatment day. Usually resolves with paracetamol.
Temporary Increased Shedding
Occasionally, patients notice slightly increased shedding for 1-2 weeks. This is normal—old hairs making way for new growth.
Uncommon Side Effects
Infection
Very rare when proper sterile technique is used. Signs include increasing redness, warmth, pus, or fever. Seek medical attention if concerned.
Prolonged Swelling
If swelling persists beyond 3-4 days, contact your clinic.
Allergic Reaction
Extremely rare since PRP uses your own blood. However, reactions to numbing cream or antiseptic are possible.
Scarring
Not expected with proper technique. PRP injections use fine needles that don't cause scarring.

Why PRP Is Generally Safe
Autologous Treatment
PRP uses your own blood, eliminating risks of allergic reaction, disease transmission, or rejection that come with foreign substances.
No Systemic Effects
PRP is injected locally. It doesn't circulate through your body or affect other systems.
Natural Process
PRP works by concentrating what's already in your blood—it's enhancing your body's natural healing.
Minimal Downtime
Most patients return to normal activities immediately. No recovery period needed.

FAQ
Is PRP safer than hair transplant?
PRP is non-surgical with minimal risks. Hair transplant is surgery with higher (though still low) risk profile.

Should I be worried about blood-borne diseases?
No. PRP uses only your own blood in a closed system.
