Common Side Effects of PRP Hair Therapy and How to Manage Them

Platelet-Rich Plasma (PRP) therapy has become one of the most sought-after solutions for individuals dealing with hair thinning and hair loss. Its appeal lies in the fact that it uses the patient’s own blood to stimulate natural hair growth, minimizing the risk of allergic reactions or rejection. Many people across Pakistan are now turning to PRP Hair Treatment in Islamabad as a non-surgical, safe, and effective alternative to hair transplant surgery. However, while PRP is considered a low-risk procedure, it’s still essential to understand that some minor side effects can occur. Being aware of these potential effects — and knowing how to manage them — ensures a smooth recovery and the best possible results.

In this blog, we’ll discuss the most common side effects of PRP hair therapy, why they happen, and how you can effectively deal with them to protect your scalp and encourage optimal hair regrowth.

Understanding PRP Hair Therapy

PRP therapy involves a straightforward process where a small amount of your blood is drawn and processed in a centrifuge to separate the platelet-rich plasma. This plasma, which contains growth factors and proteins, is then injected into your scalp where hair thinning occurs.

These growth factors help rejuvenate dormant hair follicles, improve blood circulation, and strengthen the hair roots — encouraging thicker and healthier hair over time. Since the treatment uses your own blood components, there is minimal chance of allergic or immune reactions. Still, like any medical or cosmetic procedure involving injections, some mild side effects are possible.

Why Side Effects Occur After PRP Hair Treatment

Side effects from PRP therapy are typically related to the injection process rather than the PRP itself. The scalp is a sensitive area, and repeated microinjections can cause temporary irritation or inflammation. Additionally, minor swelling or redness may appear as part of the body’s natural healing response.

It’s important to remember that these side effects are short-term, usually resolving within a few hours to a couple of days. The key is to follow your practitioner’s aftercare instructions carefully to avoid complications and promote quick recovery.

Common Side Effects of PRP Hair Therapy

Below are some of the most frequently reported side effects after undergoing PRP Hair Treatment, along with explanations and management tips.

1. Mild Swelling or Redness

Why it happens:
The injection of plasma into the scalp stimulates tissue repair and triggers an inflammatory response, which can cause temporary swelling or redness.

How to manage it:

• Apply a cold compress for 10–15 minutes a few times a day to reduce swelling.

• Avoid touching or massaging the treated area for at least 24 hours.

• Keep your head elevated while sleeping to minimize puffiness.

When it subsides: Usually within 24–48 hours.

2. Tenderness or Soreness at the Injection Sites

Why it happens:
Tiny needles are used to deliver PRP into your scalp, and this can lead to slight soreness, similar to a mild bruise.

How to manage it:

• Avoid strenuous physical activity for 24–48 hours after the session.

• Take a mild pain reliever like acetaminophen if needed (avoid anti-inflammatory drugs like ibuprofen or aspirin, as they can interfere with platelet activity).

• Do not scratch or press on the treated area.

When it subsides: Typically within 2–3 days.

3. Temporary Itching or Scalp Tightness

Why it happens:
As your scalp heals, new tissue forms, and increased blood circulation can cause an itchy sensation. This is a normal part of the healing process.

How to manage it:

• Avoid washing your hair for 12–24 hours post-treatment to allow the scalp to heal naturally.

• Use a mild, sulfate-free shampoo when washing.

• Do not use hair styling products or sprays for at least 48 hours.

When it subsides: Within 2–4 days.

4. Minor Bruising

Why it happens:
The scalp contains many small blood vessels, and needle injections can sometimes cause minor bruising.

How to manage it:

• Gently apply a cold compress during the first 24 hours.

• Avoid blood-thinning medications or supplements (like vitamin E, fish oil, or aspirin) before and after treatment unless prescribed by your doctor.

• Be patient — bruises fade naturally.

When it subsides: Usually within a week.

5. Headache or Pressure Sensation

Why it happens:
After multiple scalp injections, some patients report mild headaches due to increased blood flow and scalp sensitivity.

How to manage it:

• Take acetaminophen if needed.

• Stay well-hydrated before and after treatment.

• Rest and avoid stressful activities for the day.

When it subsides: Typically within 24 hours.

6. Temporary Shedding of Weak Hair

Why it happens:
Some patients notice mild hair shedding within the first few weeks. This is actually a positive sign that older, weaker hairs are being replaced by new, healthier growth.

How to manage it:

• Continue your recommended PRP sessions as advised by your doctor.

• Maintain a healthy diet rich in protein, iron, and vitamins.

• Avoid over-washing or using harsh hair products.

When it subsides: Usually within 3–6 weeks, followed by visible new growth.

7. Scalp Dryness or Flakiness

Why it happens:
The scalp may feel tight or slightly dry as the healing process progresses, especially if you’re prone to dry skin.

How to manage it:

• Use a mild, moisturizing shampoo.

• Avoid hot water when washing your hair.

• Do not apply oil or heavy hair serums for 2–3 days after treatment.

When it subsides: Within one week.

Rare Side Effects of PRP Hair Therapy

While uncommon, certain side effects may occur if the procedure is performed incorrectly or in non-sterile conditions. These include:

• Infection: If hygiene protocols are not followed.

• Allergic Reaction: Extremely rare, but possible if additives are used (PRP typically has none).

• Nerve or Blood Vessel Injury: Can occur with poor injection technique.

To minimize these risks, always ensure your treatment is performed by a qualified and experienced professional using sterile medical equipment in a licensed clinic.

How to Ensure a Safe and Smooth Recovery

Here are a few essential post-treatment tips to reduce discomfort and speed up healing:

1. Avoid Washing Hair Immediately: Wait at least 12–24 hours before washing your hair.

2. Skip Heat Treatments: Do not blow-dry or use flat irons for at least 48 hours.

3. Avoid Alcohol and Smoking: These can slow down healing and reduce platelet function.

4. Stay Hydrated: Proper hydration supports faster tissue repair.

5. Follow a Balanced Diet: Protein, zinc, and vitamins A, C, and E are crucial for new hair growth.

6. Attend Follow-Up Sessions: PRP works best when performed in multiple sessions. Regular visits allow your doctor to monitor your progress.

When to Contact Your Doctor

Although side effects are mild, seek medical advice if you experience:

• Persistent pain or swelling beyond 3–4 days

• Signs of infection (redness, pus, or fever)

• Unusual bleeding or severe bruising

These symptoms are rare but require professional evaluation to ensure no underlying complication.
