Clinical Trial Summary

The purpose of this clinical study is to determine if the Erchonia® ML Scanner (MLS) low level laser light device can help to regrow hair on the scalp of females experiencing hair loss or thinning.

Description:

Over 20 million women in the United States suffer from hair loss, and about 40% of those women are under forty years of age. The emotional aspects of hair loss for females include anxiety and depression, frustration and poor self-esteem. Androgenetic alopecia is a common cause of female balding and the most likely reason for excessive hair loss.

It is believed that light therapy of the scalp will provide an effective means to reduce hair loss and/or stimulate hair growth in females with androgenetic alopecia. Results of previous studies on low level laser therapy (LLLT) have demonstrated a variety of in vitro and in vivo effects including increased blood flow, accelerated wound healing, enhanced production of cytokines and other cellular mediators, increased cellular proliferation, among a panoply of other effects. Enhanced hair growth has been observed adjacent to treated areas in various animal models investigating the effects of LLLT. Uncontrolled studies in humans and spa-based therapies in Europe appear to show that the periodic application of low intensity light therapy reduces hair loss and appears to increase hair growth. The majority of these applications utilize light in the red and near-infrared portions of the spectrum.

The Erchonia MLS low level laser is being evaluated for its potential to improve the quality and quantity of hair on the female scalp. This may improve the quality of life as a result of improved self-image and may potentially delay or reduce the need for surgical procedures such as hair transplantation. A successful local therapy would mitigate or reduce the need for systemic agents such as minoxidil and finasteride, thereby minimizing the potential side effects of these therapies.

Exclusion Criteria:

• Hair loss attributable to one or more of the following conditions: tinea capsitis, secondary syphilis, discoid lupus erythematosus: Inflammation, alopecia areata, trichotillomania, telogen effluvium, anagen effluvium, traumatic alopecia.

• Use of any of the following medications presently or during the prior 6 months:

minoxidil, finasteride (or any other 5?-reductase inhibitor medications),medication with anti-androgenic properties (e.g. cyproterone, spironolactone, ketoconazole, flutamide and bicalutamide),topical estrogens, progesterone, tamoxifen, anabolic steroids, medications that can potentially cause hypertrichosis (e.g. ciclosporin, diazoxide, phenytoin and psoralens), oral glucocorticoids (inhaled glucocorticoids permitted), lithium, phenothiazines.

• Current use of other prescription and/or over-the-counter products known to affect hair growth and distribution (e.g. saw palmetto, fish oil, corticosteroids, antineoplastic agents, beta blockers, diazoxide, heparin, verapamil, warfarin, etc.).

• Medical, physical, or other contraindications for, or sensitivity to, light therapy (e.g. porphyria, photosensitizing drug therapies).

• Taking Hormonal Replacement Therapy.

• Conditions that may worsen with light therapy.

• History of poor wound healing.

• History of keloid formation.

• Prior hair restoration/transplantation surgery.

• Prior scalp reduction procedure(s).

• Other surgery to the scalp region (e.g. to remove a skin cancer lesion).

• Active skin infection, wound, or other external trauma to the scalp evaluation area.

• Active malignancy or any malignancy in the past five years in the scalp evaluation area.

• Dermatological condition (dermatitis, eczema, psoriasis, etc.) of the scalp other than female pattern hair loss.

• Significant scarring (e.g. from burns) in the scalp evaluation area.

• History of thyroid condition that may influence hair growth and loss.

• Underlying medical condition(s) known to adversely affect hair growth or hair pattern, such as HIV, connective tissue disease, inflammatory bowel disease.

• Current hair weaves.

• Use of non-breathable wigs.

• Hairstyle is a "buzz" cut, defined as hair cut to less than one inch in length.

• Tattooing of the scalp target evaluation area.

• Subject is pregnant, nursing, planning a pregnancy, or less than six months postpartum.

• Serious mental health illness such as dementia or schizophrenia; psychiatric hospitalization in the past two years.

• Developmental disability or cognitive impairment that would preclude adequate comprehension of the informed consent form and/or ability to record study measurements.

• Involvement in litigation/receiving disability benefits related in any way to the parameters of the study.
