Alopecia, or hair loss, is a concern that affects many men and women. Alopecia has its roots in a variety of etiologies. People experience hair loss as a result of aging, stress, hormonal fluctuations, vitamin deficiencies, autoimmune or inflammatory factors, and unknown reasons.
Many interventions have been studied for hair loss to varying degrees of success, but one of the most promising modalities is injection of PRP into the soft tissues of the scalp. PRP, or platelet rich plasma, is a translucent gold substance that is derived from the blood, after it is spun in a centrifuge. PRP contains growth factors that ramp up stem cell production in hair-producing cells. By injecting PRP into the scalp, patients experience: 1) a slower rate of hair loss, 2) improved retention of existing hairs, and 3) increased growth of new and quiescent hairs.
PRP has become a popular treatment modality because it is minimally invasive, quick, and effective. Three to six treatments are recommended over a 6 month period. Results are best when PRP is combined with multivitamins, folate, biotin, and sometimes topical agents such as minoxidil or Rogaine.
