Is PRP Effective for Hair Loss? Real Proofs + Insights

As beauticians at Plasma Therapy in Phibsborough, we’re often asked whether PRP really works for thinning hair. Here’s an honest, plain-English answer.

How does PRP help with hair loss?

PRP (platelet-rich plasma) is made from a small sample of your own blood. Platelets carry growth factors that play a part in the hair growth cycle. When the plasma is placed into the scalp, the aim is to support follicles that are thinning but still active, so they can grow stronger, thicker hair over time.

Because it works with your body’s own growth factors, changes build gradually. Most people need a course of 3 sessions about 4 weeks apart, and results vary from person to person.

What does the research say?

PRP for thinning hair has been studied for more than a decade, and published reviews describe it as a promising option, particularly for pattern hair loss in its earlier stages. If you’d like to read more, these are good starting points:

• Journal of Cutaneous and Aesthetic Surgery (2014)
• Stem Cell Investigation (2017)
• Journal of Cosmetic Dermatology (2019)

Research isn’t a promise for any one person, which is why we always start with a consultation.

Aside – what is PRP?

We take a small amount of blood, about the same as a routine blood test, and spin it in a centrifuge to separate the plasma, which is rich in platelets and growth factors. The plasma is then applied to the thinning areas of the scalp with very fine needles. Nothing synthetic is added.

Can PRP help with sudden hair loss?

Sudden shedding after stress, illness or a big life change often settles by itself once the cause passes, so it’s worth having it looked at before deciding on any treatment. For gradual thinning, many of our clients have seen their hair look thicker after a course of PRP, but results vary from person to person.

At your consultation, Louise looks closely at your scalp, goes through your health and what you’ve tried, and tells you honestly whether PRP is likely to help. If it isn’t the right fit, she’ll say so.
