Hair Loss (PRP)
Hair loss has many causes, the most common being genetic (pattern) baldness. PRP (platelet-rich plasma) injections are marketed for hair loss, but the evidence is limited and results vary.
Causes & risk factors
- Genetic (male- or female-pattern) hair loss
- Stress, illness or after childbirth (temporary shedding)
- Thyroid problems or iron deficiency
- Some medicines and treatments
- Scalp conditions
- Tight hairstyles or hair treatments
Common symptoms
- Gradual thinning, often at the crown or hairline
- A receding hairline (men)
- Widening parting (women)
- Sudden shedding after stress or illness
- Patchy bald spots (may point to another cause)
Tests & diagnosis
- Examination of the scalp and hair
- Iron studies
- Thyroid tests
- Scalp biopsy in some cases
Treatment & management
- Treat any underlying cause (iron, thyroid, medicines)
- Proven medical treatments for pattern hair loss
- Hair transplant surgery for suitable cases
- PRP is investigational for hair loss — evidence is limited and effects modest
- Be wary of clinics promising dramatic regrowth
When to see a doctor urgently

- Before paying for PRP — check proven options first
Frequently asked questions
Does PRP regrow hair?
Evidence is limited. Some small studies suggest modest improvement in thickness for pattern hair loss, but results vary and it is not a guaranteed or standard treatment. Proven medical options should be considered first.
Can treating iron or thyroid help my hair?
Yes, if those are the cause. Low iron and thyroid problems can cause hair thinning, and correcting them can help — which is why a check-up is worthwhile before pursuing costly treatments.
