The secondary efficacy end point will be subjective assessment of improvement. [ Time Frame: 24 weeks ]

Subjects will be instructed to fill out a questionnaire at week 24 to evaluate the overall condition of hair loss in comparison with baseline.

Subjects will be evaluated for any possible adverse effects of study drug and any symptoms and signs of scalp irritation (stinging, burning, itching)

Safety and Efficacy of Nitric Oxide Gel in Promoting Hair Growth in Male Human Subjects With Androgenetic Alopecia
Not Provided
Preclinical studies showed the Nitric Oxide (NO) gel significantly promoted hair follicle formation and growth in both rat and mouse models. The NO gel induced major physiological, developmental, and structural changes in the skin of mammals to increase the number of hair follicles, follicle stem cell development and regeneration as well as hair shaft elongation, and accelerated hair growth rate. Based on our animal model findings, the investigators hypothesize that the nitric oxide releasing gel could be used as a medical treatment for hair growth in humans. The objective of this trial is to evaluate the safety and efficacy of this NO gel (XN-001), in comparison with a placebo gel in subjects in a 24-week treatment schedule.

  • Other: Nitric Oxide (NO) Gel
    Nitric Oxide (NO) Gel is created by premixing of contents from 2 separate gel bottles. The first bottle, NO gel, is a solution of sodium nitrite (14.6mM) in distilled water with hydroxyethylcellulose (molecular weight 50,000-1,250,000) added for gel formation. The second bottle, Releasing-stimulator gel, is a solution of maleic acid (14.6mM) and ascorbic acid (14.6mM) in distilled water with hydroxyethylcellulose added for gel formation.
  • Other: Placebo gel
    The placebo gel is created by premixing of contents from 2 separate gel bottles. The first bottle is phosphate-buffered saline. The second bottle is the second gel bottle (Releasing-stimulator gel) as described in experimental arm.
  • Experimental: Nitric Oxide (NO) Gel
    Intervention: Other: Nitric Oxide (NO) Gel
  • Placebo Comparator: Placebo Gel
    Intervention: Other: Placebo gel
