Brief Summary
The goal of this clinical trial is to evaluate whether topical Minoxidil can restore hair pigmentation in individuals with non-pathological graying hair. The study population includes male and female participants aged \[18to65\] who have non-pathological graying of hair, meaning their graying is not due to any underlying medical conditions. The main questions it aims to answer are: Does topical Minoxidil improve hair pigmentation in individuals with non-pathological graying hair? What medical problems do participants have when topical use minoxidil? Researchers will compare participants receiving topical Minoxidil to those receiving a placebo to determine whether Minoxidil has a significant effect on restoring hair pigmentation. Participants will: Topical use minoxidil or a placebo twice a day for 12 months Visit the clinic once every months for checkups and tests Report any adverse effects or changes in hair characteristics throughout the study.

Outcome Measures
Primary Outcomes (1)
Reduction in the appearance gray hair grade
we divided gray hair appearance into 11 progressive levels of severity, ranging from grade 0: fully pigmented(%), to grade 10:completely unpigmented(100%).Two trained physicians (blinded to the trial group assignments) used a gray hair appearance color scale to rate patients' gray hair appearance to determine whether the primary outcome definition was met.
From enrollment to the end of treatment at 12 months
Secondary Outcomes (4)
Reduction 2 level in the appearance gray hair grade
From enrollment to the end of treatment at 12 months
White hair percent change from baseline

Study Arms (2)
5%minoxidil group
EXPERIMENTALParticipants will apply high concentration Minoxidil (e.g., 5% Minoxidil solution) to the scalp twice daily for 12 months. The main purpose of the treatment is to evaluate the efficacy of high-concentration Minoxidil for treating non-pathological graying and to monitor its safety and tolerability.
Placebo Group
PLACEBO COMPARATORThis group will receive a placebo solution (similar in appearance and odor to Minoxidil but without the active ingredient), applied to the scalp twice daily for 12months. This placebo group will serve as a control for comparing the effects of Minoxidil on non-pathological graying of hair.
Interventions
The patient will apply 5% Minoxidil topical solution to the scalp twice daily, with 7 sprays (approximately 1 mL) per application, for a duration of 12 months.
The patient will apply placebo to the scalp twice daily, with 7 sprays (approximately 1 mL) per application, for a duration of 12 months.
Eligibility Criteria
You may qualify if:
- The patients included in the study were those with a visible gray hair grading score of 2 or higher at screening and baseline visits, with depigmented hair shafts observable under dermoscopy.
