Strategies to Minimize Pain During Platelet-Rich Plasma Scalp Injections

This study found that platelet-rich plasma prepared using a double-spin method may be more effective for treating female pattern hair loss than single-spin PRP, although VEGF concentration was unaffected by either preparation method.

This study investigates the effects of ice cooling and vibration on reducing pain during platelet-rich plasma injections for alopecia, especially due to concerns about lidocaine reducing PRP efficacy.

This study observed that using ice pack compression or a vibration anesthesia device reduced pain during inactivated PRP scalp injections in patients with alopecia, suggesting both as inexpensive and accessible pain-relief options.
