Platelet-Rich Plasma (PRP) Treatment for Androgenetic Alopecia

Introduction to PRP Treatment

The American College of Periodontology recommends administering PRP as three intradermal scalp injections spaced one month apart, combined with topical minoxidil 5% twice daily for superior outcomes compared to either treatment alone 1, 2

Nonactivated PRP demonstrates 31% greater increases in hair count and total hair density compared to activated PRP, according to the Periodontology 2000 guidelines 1, 2, 3

The treatment protocol involves administering three treatment sessions, each spaced exactly one month apart, with concurrent topical minoxidil 5% applied at 1 mL twice daily throughout the treatment period and beyond, as recommended by the Periodontology 2000 guidelines 1, 4, 5, 6, 7
Maintenance PRP injections every 6 months are required to sustain results, according to the Praxis Medical Insights guidelines 3

Initial improvements in hair density become visible at 2-3 months, with a 25% improvement at 2 months predicting sustained response at 6 months, as reported in the Periodontology 2000 guidelines 1
At 6 months post-treatment, hair density increases by 1.74 times, hair diameter increases by 14.3 times, and telogen phase hair decreases by 9.3 times, according to the Periodontology 2000 guidelines 1, 4

Combination therapy with PRP and topical minoxidil 5% is significantly more effective than either monotherapy, and both monotherapies are superior to placebo, as stated in the Periodontology 2000 guidelines 1, 6, 2, 8
Nonactivated PRP produces superior clinical outcomes, and activation should be avoided, according to the Periodontology 2000 guidelines 1, 2
Continuous treatment is required to maintain benefits, and discontinuation results in loss of gains, as reported in the Praxis Medical Insights guidelines 3
Mild to moderate androgenetic alopecia responds most favorably to PRP treatment, with more severe grades showing variable results, according to the Periodontology 2000 guidelines 1

Pain during injection is the primary complaint, though PRP is generally better tolerated than some alternatives, as reported in the Periodontology 2000 guidelines 7

Platelet-rich fibrin (PRF) is emerging as a potentially superior alternative to PRP, offering theoretical advantages with similar efficacy and lower cost, according to the Periodontology 2000 guidelines 1, 3

The Indian Association of Dermatologists recommends using manual double-spin method for PRP preparation with target platelet concentration of 1.0-1.5 million platelets per microliter 9
Autologous blood should be drawn and processed immediately using standardized centrifugation protocols 9

The Indian Association of Dermatologists suggests delivering 3-5 treatment sessions spaced exactly one month apart, with 5-7 mL PRP per session using 30-gauge × 4 mm needles 9
Point-by-point injection technique at 90-degree angle, 2-4 mm depth, and spacing injections 1 cm apart across mapped areas of hair loss is recommended 9
Pharmaceutical-grade topical anesthetic should be applied before injection to minimize pain 9

Consider adding finasteride and multivitamin supplements as background therapy, as recommended by the Indian Association of Dermatologists 10

The Indian Association of Dermatologists notes that PRF shows promise as a potentially superior alternative to PRP, with theoretical advantages including lower cost and easier preparation 9, 10
PRF demonstrates clinical efficacy in androgenetic alopecia with a similar safety profile to PRP 10
