Willing to maintain shampooing frequency and general hair regime for the duration of the study 6. Willing to not cut hair for the duration of the study 7. Willing to have area of hair prepped for Trichoscan analysis 8. Healthy as determined by laboratory results, medical history, and physical exam 9. Subjects must agree to comply with study procedures 10. Has given voluntary, written, informed consent to participate in the study
Exclusion criteria
1. Women who are pregnant, breastfeeding, or planning to become pregnant during the course of the trial. 2. Women who have begun hormonal birth control or hormone replacement within 6 months of randomization 3. Subjects taking natural health products, including multi-vitamins, botanicals and other nutraceuticals, within 2 weeks of randomization and for the duration of the study 4. Subjects with Fitzpatrick scores over V, which stems from the sensitivity of the testing method (requires a degree of color contrast when evaluating hair relative to skin) 5. Subjects having underwent a form of treatment for thinning hair, including prescription drugs or light therapy within 6 months of randomization 6. Medical history of diagnosed alopecia and/or trichotillomania (compulsive hair pulling). Medical history may be assessed by the Qualified Investigator 7. Subjects currently using hair extensions 8. Subjects with psoriasis or any active dermatological condition of the scalp at randomization that in the opinion of the qualified investigator would interfere with the clinical evaluations 9. Medical history of thyroid disorders or with TSH levels outside the normal range (0.4-4.5 ±0.05) as assessed by the Qualified Investigator 10. Unstable medical condition as determined by qualified investigator 11. Clinically significant abnormal lab results at screening will be assessed by the Qualified Investigator 12. History, or current diagnosis of any cancer (except for successfully treated basal cell carcinoma in an area other than the scalp) diagnosed less than 5 years prior to screening. Subjects with cancer in full remission more than 5 years of diagnosis are acceptable. 13. Alcohol abuse or drug abuse within the past 6 months 14. Consumption of greater than 2 standard alcoholic drinks per day 15. Use of medicinal marijuana 16. Participation in a clinical research trial within 30 days prior to randomization 17.
