Can PRP Regrow Thinning Hair? Dermatologist Insights

Thinning hair can be distressing for both men and women, but innovative, non-surgical treatments like Platelet-Rich Plasma (PRP) therapy are offering new hope. According to Sara Petro, MS, PA-C of MDCS Dermatology, PRP has become one of the most promising regenerative approaches for stimulating natural hair growth—especially in patients seeking alternatives to medication or surgery.

How PRP Therapy Works

PRP therapy uses your body’s own platelets, which are rich in growth factors that help repair and regenerate tissue. During treatment, a small amount of your blood is drawn, spun in a centrifuge to isolate platelets, and then carefully injected into the scalp. These growth factors work to stimulate dormant hair follicles, strengthen existing strands, and encourage new growth over time.

What Conditions Can PRP Help With?

PRP can effectively treat several types of hair thinning, including:

• Androgenetic alopecia (male or female pattern hair loss)
  

• Postpartum or stress-related shedding
  

• Thinning due to aging or hormonal changes
  It’s often used in combination with other therapies such as topical minoxidil or oral medications to enhance results.
  

What to Expect During and After Treatment

The procedure typically takes less than an hour and involves minimal discomfort. Patients may notice mild scalp tenderness or redness for a day or two. For best results, Sara Petro, MS, PA-C recommends a series of 3–4 initial treatments spaced a month apart, followed by maintenance sessions every 6–12 months.

Why PRP Is a Safe and Natural Option

Because PRP is derived from your own blood, the risk of allergic reaction or complications is extremely low. At MDCS Dermatology, treatments are performed under expert medical supervision, ensuring precise application and consistent outcomes.

When to Expect Results

Patients often begin noticing thicker, healthier hair within 3–6 months of treatment. Continued improvement can be seen over time as hair cycles naturally renew.

If you’re ready to take control of hair thinning and restore your confidence, PRP therapy may be the solution.
