Laser Assisted Delivery of Minoxidil in Androgenetic Alopecia
The Safety and Efficacy of Fractional Ablative 10, 600nm CO2 Laser-assisted Treatments for Male Pattern Hair Loss: a Randomized Cohort Study Comparing Stand-alone Laser Treatment, Laser Assisted Drug Delivery of Minoxidil 2% Solution , and Laser Assisted Drug Delivery of Minoxidil 2% Solution Plus Self-administration of Minoxidil 5% at Home.
Study Overview

Detailed Description
Male pattern hair loss (MPHL) is a common, frustrating, and difficult to manage scalp disease with few treatment options available. Though the mechanism remains unclear, minoxidil is a well-established treatment for MPHL. With the advent of laser assisted drug delivery, the investigators seek to investigate the use of laser assisted minoxidil delivery to improve bioavailability, and subsequent hair growth for subjects MPHL. With an improved clinical outcome and increased treatment efficiency, patient quality of life would be enhanced and fewer at home topical treatments with minoxidil may be required. Additionally, this study will assist in understanding the effects of stand-alone laser therapy on hair growth and may also be used as a background or framework for a growing number of studies investigating this technology as a drug delivery system.
MPHL, also known as androgenetic alopecia, is a non-scarring alopecia resulting in gradual hair loss localized to the scalp. In men, this progressive hair loss disorder results in characteristic thinning of hair over the vertex and frontal regions.1 The Hamilton-Norwood scale categorizes this typical clinical progression.2 While the pathogenesis of MPHL is not entirely elucidated, it has been proposed to be an age and hormone dependent process with dihydrotestosterone playing a significant role.2,3 Genetic factors may also contribute to the disease.4
Topical minoxidil is an FDA approved treatment for MPHL. Minoxidil 2 and 5% solution are known to increase hair regrowth in men with androgenetic alopecia.7 While the mechanism remains unknown, it has been proposed minoxidil increases the duration of anagen and vascular supply to the follicular structure.8
Topical treatments for MPHL such as minoxidil have limited efficacy, as topical delivery of medication has low bioavailability.9 With the advent of fractionated ablative and non-ablative laser technologies, more efficient drug delivery to the level of the superficial epidermis and dermis is now possible.
The outermost layer of skin, the stratum corneum, impedes the diffusion of topical medications to follicular structures in the dermis and hypodermis. 9 Ablative fractionated laser devices create vertical channels, permitting topical medication to breach the skin's top layer, the stratum corneum, and reach deep skin layers where hair follicles reside.9
Both ablative and non-ablative fractionated laser treatments augment collagen deposition and cause growth factor mediated changes to skin ultrastructure.10 Non-ablative fractionated laser therapy in MPHL patients improves hair density with and without topical administration of growth factor.10 Our proposed study confers an additional mode of treatment beyond laser-only therapy by using an ablative fractionated laser to deliver minoxidil 2% solution percutaneously.
Herein, the investigators seek to further optimize patient treatment by investigating a combination of these treatment modalities for management of MPHL. The investigators hypothesize that fractionated ablative 10,600nm CO2 laser treatment and laser assisted drug delivery of minoxidil 2% solution will result in increased hair growth. With this improved clinical outcome and increased treatment efficiency, patient quality of life will be enhanced and fewer at home topical treatments may be required.
