A PRP appointment is more than a quick injectable treatment. Your own blood is used to create a platelet-rich plasma that is then placed into targeted areas of the scalp or skin, so the quality of your preparation can influence how comfortable the appointment feels and how well your body supports the recovery process. If you are researching how to prepare for PRP, the aim is simple: arrive well hydrated, well informed and ready to follow personalised clinical advice.
At VitaGlow Clinic, PRP is approached as a condition-led treatment, whether your concern is hair thinning, reduced hair density, tired-looking skin, acne scarring or early signs of ageing. Preparation is never about chasing perfection. It is about reducing avoidable variables so your treatment plan has the strongest possible foundation.
What PRP preparation is designed to do
PRP, or platelet-rich plasma, starts with a small blood draw. The sample is processed to separate and concentrate the platelet-rich portion of your plasma. Platelets contain growth factors that play a role in the body’s natural repair processes. When PRP is introduced into the scalp or skin through injections or microneedling, it is intended to support skin quality and hair health over time.
The treatment is not a substitute for identifying an underlying cause of hair loss, fatigue or skin changes. For example, low iron, thyroid concerns, hormonal changes, recent illness and significant stress can all affect hair shedding. A thorough consultation helps establish whether PRP is appropriate and whether blood testing or a broader wellness plan may be useful alongside it.
Good preparation supports a smoother blood draw and helps minimise factors that can increase bruising or irritation. It also gives your practitioner a clear picture of your health, medication and goals, which is essential for safe, personalised care.
How to prepare for PRP in the week before
Start by being open about your health history. Tell your practitioner about medical conditions, allergies, recent illnesses, active skin infections, pregnancy or breastfeeding, and any medicines or supplements you take. This includes prescribed medication, over-the-counter pain relief, herbal supplements and vitamins.
Some medicines and supplements can affect bleeding, bruising or platelet activity. Do not stop prescribed medication without speaking to the clinician who prescribed it. Your PRP practitioner can explain which products may need to be avoided and for how long, but any changes to essential medication should always be agreed with your GP or specialist first.
Where clinically appropriate, you may be advised to avoid anti-inflammatory painkillers such as ibuprofen, aspirin-containing products and certain supplements before treatment. This is not a blanket rule for every client. The right advice depends on why you take them, your medical history and the treatment area. Paracetamol is often the preferred option for discomfort when suitable for you, but check this during your consultation.
Alcohol can contribute to dehydration and may increase the likelihood of bruising for some people. Avoid it for at least 24 to 48 hours before your appointment, unless your practitioner gives different guidance. It is also sensible to avoid smoking or vaping where possible, as these can affect circulation and the body’s healing environment.
Hydration makes a practical difference
Drinking enough water is one of the most useful ways to prepare for PRP. A well-hydrated blood sample is generally easier to collect, particularly if you have previously found blood tests difficult. Aim to drink water consistently throughout the day before your appointment rather than trying to catch up with several large glasses just beforehand.
Eat normally on the day of treatment unless you have been given specific instructions. Arriving on an empty stomach can leave you light-headed during a blood draw, especially after a busy day at work or a poor night’s sleep. Choose a balanced meal containing protein, fibre and slow-release carbohydrates, rather than relying on sugary snacks or excessive caffeine.
If you are prone to feeling faint during blood tests, let the clinic know in advance. A clinically trained practitioner can make adjustments to keep you comfortable, such as positioning you appropriately and allowing extra time after the blood draw.
Prepare the scalp or skin, not just the calendar
For scalp PRP, wash your hair on the morning of the appointment or the evening before using your usual gentle shampoo. Come with a clean scalp, free from dry shampoo, heavy styling products, hair fibres, oils or thick leave-in treatments. These products can make the treatment area harder to assess and clean properly.
Try not to colour your hair, use harsh scalp treatments or have a chemical service immediately before PRP. If your scalp is irritated, sunburnt, flaky or has an active infection, treatment may need to be postponed. Let your practitioner know if you have had recent scalp sensitivity or a flare-up of a skin condition such as psoriasis or eczema.
For facial PRP, arrive with clean skin where possible. Avoid retinol, exfoliating acids, strong vitamin C products, facial waxing and other potentially irritating treatments in the days leading up to your session. The precise timing depends on what you use and whether PRP is being combined with microneedling, so ask for tailored guidance rather than guessing.
Avoid excessive sun exposure before your appointment. Skin that is sunburnt or inflamed should not be treated, and protecting your skin beforehand helps create a calmer starting point for recovery.
Plan for the appointment and early recovery
PRP appointments are usually straightforward, but give yourself breathing room. Avoid scheduling your treatment directly before a major event, an intense workout, a long night out or an important video call if possible. The treated area may look red, feel tender or develop mild swelling afterwards. These effects are usually temporary, but they are easier to manage when you do not have to rush.
Wear comfortable clothing and, for scalp treatments, choose a top that does not need to be pulled tightly over your head afterwards. If you are having facial PRP, avoid arriving in heavy make-up. You may also want to bring a hat for the journey home, provided it is loose, clean and does not rub against the treated area.
A treatment series is often recommended because hair and skin changes happen gradually. Your practitioner will discuss realistic timings based on your concern, but do not judge your result after a few days. PRP works with biological processes, not an instant cosmetic cover-up.
What to avoid immediately after PRP
Your aftercare will depend on whether PRP was used on the scalp, face or another area, and whether it was combined with microneedling. Follow the specific instructions provided at your appointment. In general, avoid touching the area unnecessarily, strenuous exercise, alcohol, swimming pools, saunas and steam rooms for the period advised by your practitioner.
For facial treatment, pause active skincare products until your skin has settled. Keep the area clean, use gentle products approved by your practitioner and wear broad-spectrum SPF when appropriate. For scalp PRP, you may be asked not to wash your hair for a set period or to avoid certain styling products. Do not apply oils, medicated scalp products or topical hair-loss treatments until you have been told it is suitable to restart them.
Mild soreness, pinpoint bleeding, redness or swelling can occur. Contact your clinic promptly if you experience worsening pain, spreading redness, unusual discharge, a fever or any symptom that concerns you. A safe clinic should make aftercare advice clear and be available to support you.
Getting the most from your PRP plan
PRP can be a valuable option for clients in Hemel Hempstead, St Albans, Watford and Kings Langley who want a medically informed approach to stronger-looking hair or brighter, healthier-looking skin. Its best role is within a plan that respects your individual health, lifestyle and goals.
Support your treatment with the basics that genuinely matter: regular sleep, adequate protein, hydration, stress management and investigation of persistent symptoms such as sudden shedding or ongoing fatigue. If your body is signalling that something has changed, treating the cause alongside the visible concern is often the more effective route.
Before booking, arrange a consultation and bring an honest list of medications, supplements and recent treatments. Clear preparation gives your practitioner the information needed to make your PRP treatment safe, personalised and focused on results that make sense for you.
