Platelet-Rich Plasma Therapy for Hair Loss

PRP therapy for hair loss involves a three-step process:

• A trained professional draws blood from the patient's arm.
• The technician then places the blood in a centrifuge to separate the platelets from the other blood components.
• The practitioner then injects the concentrated platelets (PRP) back into the areas of the scalp with thinning hair or balding.

As a result, the growth factors in the PRP stimulate the hair follicles, increase blood supply to the area, and promote the growth of new, thicker hair.

Several studies have shown the effectiveness of PRP therapy in treating hair loss:

• A 2022 review found that PRP may stimulate hair growth and thickness, as well as protect hair follicles from prematurely shedding.
• A 2020 review of 13 studies found that PRP may help increase hair thickness and density.
• A 2018 review found that PRP may trigger hair growth by increasing blood supply to the hair follicle.
• A systematic review of 92 patients from 6 randomized controlled trials showed that PRP has a positive effect on female pattern hair loss treatment by increasing hair thickness and density.

It typically takes 3 to 6 months to start seeing noticeable results from PRP therapy. However, some patients may notice improvements in hair texture and thickness as early as 2 weeks after the initial treatment. Nevertheless, results can vary from person to person. Therefore, for optimal results, most experts recommend a series of 3 to 5 PRP treatments, spaced about 4 to 6 weeks apart. Additionally, maintenance treatments may be needed every 6 to 12 months to sustain the benefits.

PRP therapy can furthermore be combined with other hair loss treatments to enhance its effectiveness:

• Minoxidil (Rogaine) is a topical treatment that works well in conjunction with PRP to promote hair growth.
• Finasteride is an oral medication that blocks the hormone responsible for hair loss and may therefore be prescribed alongside PRP therapy.
• Microneedling can be performed in combination with PRP to create micro-channels that allow the PRP to penetrate deeper into the scalp.

Maintaining a healthy lifestyle and diet can complement PRP therapy and support hair health:

• Stay hydrated by drinking plenty of water.
• Eat a nutrient-rich diet that includes foods high in vitamins and minerals essential for hair growth, such as:
  • Protein (meat, eggs, legumes)
  • Iron (red meat, spinach, lentils)
  • Zinc (seafood, nuts, seeds)
  • Biotin (eggs, salmon, avocado)
  • Vitamin C (citrus fruits, bell peppers, broccoli)
• Avoid excessive stress, as stress can contribute to hair loss.
• Get enough sleep, as sleep is crucial for hair growth and overall health.
