Abstract
Objective: Assess the perceived efficacy of stabilized, super-oxidized hypochlorous acid (HOCl) in hair transplant surgical procedures intraoperative and postoperative.
Background: Stabilized, super-oxidized hypochlorous acid (HOCl) is highly effective against bacterial, fungal, and viral microorganisms. In addition, topical HOCl will increase tissue oxygenation of wound sites to aid in healing. This molecule represents an ideal agent for intraoperative and postoperative use in hair restoration procedures that involve thousands of small wounds.
Methods: 35 patients were enrolled in a multi-site study following repeat or initial hair restoration surgery. Surgeons were provided a 500 mL trigger spray bottle of HOCl spray liquid for use prior to and throughout the surgical procedure. Patients were provided with a ten-day supply of HOCl for postoperative care. Two formulations were utilized, one was applied to the recipient sites while the other was applied to the donor area postoperatively. Patients and surgeons were provided with observational surveys regarding healing and usage of the products.
Results: Statistical analysis found 56% had significant reduction in the amount of erythema compared to their current wound healing regimen. More than half of the patients (54%) had significant improvement of pruritus. The compliance rating for this study was 97% among patients. Surgeons were queried on the overall efficacy. There were no incidences of donor or recipient tissue necrosis.
Conclusion: The evolution of hair restoration surgery has been accompanied by large numbers of grafts being implanted. This change necessitates the requirement for optimum intraoperative and postoperative care. Topical, stabilized hypochlorous spray represents a major advance in wound cleansing and healing and offers the theoretical benefits of reducing tissue necrosis through oxygenation.

INTRODUCTION

Surgeons performing hair restoration procedures routinely create thousands of micro incisions in the donor and recipient areas. This procedure creates a very unique set of challenges. Intraoperative bleeding control can become an issue. No spray solutions have shown a benefit regarding hemostasis. Hypochlorous acid (HOCl) may be the exception. Postoperative complications in hair restoration surgery are infrequent, but include infection, swelling, bleeding, and, rarely, tissue necrosis. There are many types of topical products available for postoperative wound care but few have been evaluated in clinical trials.1 There is scant evidence that any one topical agent speeds healing of surgical wounds by secondary intention more than another agent.1 Compelling evidence exists in the literature that demonstrates that topical HOCl represents an ideal agent of choice for postoperative care in hair restoration surgery patients.7-10

Stabilized Hypochlorous
HOCl is a naturally occurring molecule whose mechanism of action is achieved through white blood cells. Specifically, neutrophils augment host immunity when they release HOCl to aid in the destruction of pathogenic organisms such as bacteria, fungi, and yeast. Unlike antibiotics, when used topically as a stabilized formula, there is no evidence microbial resistance will emerge.8

Antimicrobial Properties
Studies show HOCl exhibits broad-spectrum antimicrobial properties at concentrations of 0.1 to 2.8 micrograms/mL.11 The literature regarding its efficacy in the reduction of Staph aureus is abundant.21-25 A closer look at these various studies (which were performed with HOCl gels, sprays, and solutions) reveals that topical HOCl is impacted by both pH and formulation stability.11,12 Degradation and instability issues of the HOCl
