Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The potential participants are screened by the investigator for inclusion in the study. The eligible participants are enrolled by investigator and provided with a "Numbered Container" that is identical to all other containers and contains the same information on the label, except for the number. The investigator is blinded to the product randomized with the
numbered containers labelled prior to delivery to investigational site. Product allocated as participants are enrolled in sequential order
Methods used to generate the sequence in which subjects will be randomised (sequence generation)

Efficacy
Statistical methods / analysis
A total of 33 participants are required to have a 90% chance of detecting a significant change (at the 5% level), in hair density from baseline in the experimental group of 2 mm/cm3. 40 participants per group will be recruited to allow for withdrawals.

Statistical tests will be used to compare differences between groups for hair growth (density, strength and thickness), loss and colour as well as blood markers and questionnaire results. The change in hair density and hair loss will be measured as a within group mean difference change from baseline over the 12 weeks of treatment as well as a comparison between the groups. Statistical analysis will be conducted based on the normality of the data and mean and variance statistical significance (p<0.05) will be calculated using ANOVA and t-tests or Mann-Whitney test if appropriate.

Summary
Brief summary
Following preliminary screening via telephone, potential participants will attend the clinic for an information session and will be required to provide their consent for inclusion in the trial. Consenting participants will undergo a health assessment including lifestyle, current medications and medical history; this data will be used for the comprehensive screening and to provide contextual data for the study.

Once enrolled in the trial, participants will be randomly allocated to either one of 2 placebo comparator groups or one of two investigational intervention groups. Prior to treatment, participants will undertake various hair assessments including photographs of scalp (unidentifiable), hair comb/count test, hair tug/pull test, densitometry (haircheck®) and also undertake a blood test.
Participants will be asked to consume or apply the allocated product according to the dose prescribed and attend the clinic every month for a repeat of baseline measures excluding the blood test.
At week 12 participants will be asked to attend the clinic for a final assessment including all measures undertaken at baseline, a final blood test and an exit interview.
