What to Expect During Your First PRP Hair Treatment Session

Introduction

Booking your first PRP hair treatment is an exciting step, but it is completely normal to feel a little nervous beforehand. Needles, blood samples and scalp injections can sound daunting if you have never experienced them before. The good news is that PRP is a straightforward, well tolerated treatment, and knowing what to expect can make the whole experience far more relaxed.

In this guide, we walk you through every stage of your first session, from the initial consultation and preparation to the treatment itself, aftercare and the results you can look forward to in the months ahead.

A Quick Overview of PRP

PRP stands for platelet rich plasma. It is made from a small sample of your own blood, which is spun in a centrifuge to concentrate the platelets. These platelets contain growth factors that help stimulate weakened hair follicles, improve blood supply to the scalp and encourage thicker, healthier growth. Because it uses your own blood, the treatment is natural and carries a very low risk of allergic reaction. You can find full details on our PRP (Platelet-Rich Plasma) Hair Therapy page.

Before Your Appointment: The Consultation

Your PRP journey begins with a consultation, which is often the most important part of the whole process. This is your chance to ask questions and make sure the treatment is right for you.

During the consultation, your practitioner will usually:

• Examine your scalp and the pattern of your hair loss
• Ask about your medical history, medications and any allergies
• Discuss how long you have been losing hair and whether it runs in your family
• Explain how PRP works and what results are realistic for you
• Talk through the number of sessions you are likely to need and the costs involved

Some clinics may also suggest a blood test to check for underlying causes of hair loss, such as low iron, thyroid problems or vitamin deficiencies. Addressing these can make a real difference to your results.

A good practitioner will be honest with you. If PRP is unlikely to help, or if another treatment would suit you better, they should tell you.

How to Prepare for Your First Session

A little preparation helps your appointment go smoothly and can improve your comfort on the day. Common advice includes:

• Stay well hydrated. Drinking plenty of water in the day or two before makes it easier to draw blood.
• Eat a proper meal. Having breakfast or lunch beforehand helps prevent light headedness during the blood draw.
• Avoid alcohol for at least 24 to 48 hours before your session.
• Check your medication. You may be advised to pause anti inflammatory painkillers, such as ibuprofen or aspirin, for several days, as they can affect platelet function. Never stop prescribed medication without speaking to your doctor first.
• Wash your hair on the morning of your appointment and avoid styling products, sprays or oils.
• Limit smoking, as it can reduce blood flow and affect healing.
• Wear comfortable clothing with sleeves that roll up easily for the blood sample.

If you feel anxious about needles, let your practitioner know in advance. They can talk you through each stage and take extra steps to keep you comfortable.

What Happens During Your First PRP Session

Most PRP appointments last between 45 minutes and an hour. Here is what typically happens, step by step.

1. Arrival and final checks. Your practitioner will confirm your medical details, answer any last questions and ask you to sign a consent form. Some clinics take photographs of your scalp so progress can be tracked over time.
2. Taking the blood sample. A small amount of blood, usually similar to a routine blood test, is drawn from your arm. This takes only a few minutes and most people feel just a quick scratch.
3. Preparing the PRP. Your blood is placed in a centrifuge and spun for around ten to fifteen minutes. This separates it into layers, and the platelet rich plasma is carefully collected. You can simply relax while this happens.
4. Numbing the scalp. While the PRP is being prepared, a numbing cream, cooling device or local anaesthetic may be applied to the treatment area to reduce discomfort.
5. Cleansing the scalp. The area is cleaned thoroughly with an antiseptic solution to keep everything hygienic.
6. The injections. Using a very fine needle, the practitioner injects the PRP into the thinning areas of your scalp in a series of small, evenly spaced points. This part usually takes 15 to 20 minutes, depending on the size of the area being treated.
7. Finishing up. Once the injections are complete, your scalp is gently cleaned and you will receive aftercare advice before heading home.

Does it hurt?

This is the most common question people ask. Most patients describe the sensation as a mild pinching or pressure rather than real pain, especially when numbing is used. Areas near the hairline and temples can feel a little more sensitive than the crown. Your practitioner will check on your comfort throughout and can pause at any time.

Straight After Your Treatment

You will be able to go home or return to work straight away, and most people do not need anyone to accompany them. Immediately after the session, you may notice:

• Mild tenderness or a feeling of tightness in the scalp
• Slight redness or swelling
• Small pinpoint marks at the injection sites
• A mild headache

These effects are normal and usually settle within 24 to 48 hours. Minor bruising is possible but tends to fade within a few days.

Aftercare Tips for the Best Results

Following your practitioner’s aftercare advice helps protect your scalp and supports the best possible outcome. Typical guidance includes:

• Avoid washing your hair for at least six to twelve hours after treatment
• Use a gentle, mild shampoo for the first few days
• Avoid hair dyes, chemical treatments and heat styling for around 48 to 72 hours
• Skip strenuous exercise, saunas, steam rooms and swimming for a day or two
• Avoid alcohol and smoking for at least 24 hours
• Do not massage or scratch the treated area
• Protect your scalp from strong sunlight
• Avoid anti inflammatory painkillers for a few days unless your doctor advises otherwise, as they may interfere with the healing response

If you notice anything unusual, such as increasing pain, heat or signs of infection, contact your clinic promptly.

When Will You See Results?

It is important to remember that one session is just the beginning. PRP works gradually by supporting your natural hair cycle, so results take time.

• First few weeks: no visible change is expected yet, as the growth factors begin working beneath the surface.
• One to two months: many people notice less shedding.
• Three to six months: hair often feels thicker and fuller, with improved density.
• Six months onwards: the full benefits become visible, especially after completing your course.

Most people need three to four sessions spaced four to six weeks apart, followed by maintenance sessions every six to twelve months.

Thinking About Your Skin Too?

Many patients who enjoy the natural approach of PRP for hair go on to try it for their complexion. PRP (Platelet-Rich Plasma) Skin Therapy can help improve skin texture, soften fine lines, reduce scarring and restore a healthy glow, using the same regenerative principle.
