The key ingredient is AminoMar C™ marine complex, an organic form of silica derived from Equisetum sp. (horsetail), vitamin C derived from Malpighia emarginata (acerola cherry), microcrystalline cellulose (E460), natural orange flavor, magnesium stearate, hypromellose, and glycerol. The AminoMar C ™ is an active ingredient which has been trademarked and comprises of a proprietary blend of shark powder and mollusc powder. It is derived from sustainable marine sources. Viviscal provides essential nutrients to nourish hair naturally from within. Viviscal works in 4 stages (see below) over several months of use to improve the appearance of thinning hair. STAGE 1: Nourishes the hair follicles STAGE 2: Strengthens and promotes the growth of terminal hairs. Terminal hair is defined as coarse hair, short or long, found on the scalp with minimum cross-sectional diameter of 40 micrometers. Vellus hair is defined as fine, short hairs found on the scalp with maximum cross-sectional diameter of 40 micrometers. STAGE 3: Supports the growth of hair where it has slowed down or temporarily stopped STAGE 4: Hair becomes stronger, healthier and more vibrant Ingestion of Viviscal over a six (6) month period will strengthen and promote the growth of terminal hairs in female subjects, ages 21-75 years of age with self-perceived thinning hair associated with poor diet, stress, hormonal influences or abnormal menstrual cycles. The primary endpoints will be individual hair counts and favorable analysis using the Nikon CoolPix 4300 with 3GEN Dermlite Foto37 or Nikon D90 camera with a Nikor 105 mm macro lens for phototrichogram analysis at the end of the six (6) month period. The secondary endpoints will be favorable improvements in terminal hair diameter measured by the Dino-Lite Digital Microscopic and positive feedback on the Quality of Life and Self-Assessment questionnaires after six (6) months of Viviscal ingestion. All patients enrolled must be identifiable throughout the study. The Investigator will maintain a personal list of patient numbers and patient names to enable records to be found at a later date and the list will be stored in a locked cabinet. Subject numbers consist of a 2 digit number from 01 to 40. Patients will be randomized to active or placebo supplements (1:1 ratio) using a randomization table prepared prior to the start of the study by a non-participating staff member at the office of the Investigators. The study blind will not be broken until the end of the study. All test product and placebo will be labeled with subject numbers per the non- participating staff member. Subjects will be assigned a subject number in numerical order as enrolled. Randomization will occur by assignment to either New Viviscal professional strength supplement or placebo with 1:1 ratio. Subjects who terminate their study participation for any reason, regardless of whether study medication was used or not, will retain their randomization number. Subjects will be assigned a two-digit number which will uniquely identify every subject on the study. This number will remain with the subject throughout the study and should be used in all references to the individual in this study. No number will be reassigned once the study begins. Subjects at the ASIRC will start with 01 to 20 and at DeNova Research 21 to 40. Patients will be identified solely by this number and any paper records which reflect electronic data or relationships of those data with patient confidential information are kept in locked cabinets. Visit Procedures Pre-Study Procedures 1. Candidate subjects will be screened with the eligibility requirements by telephone prior to Visit 1. 2. Candidate subjects will be assigned an appointment time for visiting the clinic. Visit 1: Baseline, Day 0 1. Individuals will be given an informed consent (IC) document \& photographic release form, HIPAA form, confidentiality agreement to read. They will have all of their study related questions answered by the Investigator or his/her designated staff and if they agree, they will sign two copies of the IC/Photography release form, two copies of the HIPAA form, and one copy of the confidentiality agreement. Subjects will be given one copy of the signed IC/Photography release and of the HIPAA agreement to keep, with one copy of each document remaining at the testing facility in the subject's file. 2. Investigator and/or Study Coordinator will review with subject and complete the checklist for all inclusion and exclusion criteria. 3. Investigator and/or Study Coordinator will review with subject and complete the checklist for medical history and concomitant medications. 4. Investigator and/or Study Coordinator will review with subject and complete the General Lifestyle Questionnaire. The General Lifestyle Questionnaire may be found in Appendix IV. 5. Subjects will be given a Quality of Life Questionnaire to read and complete. The Quality of Life Questionnaire may be found in Appendix V. 6. Candidate subjects will receive a brief physical exam, including examination of the scalp, to rule out any immediately observable medical issues and any scalp alopecias/scalp disorders that are unacceptable for qualification. The physical will additionally include vital signs (pulse and blood pressure), weight and height. 7. Candidate subjects of childbearing potential will complete a urine pregnancy test prior to product distribution. 8. Candidate subjects who have completed all the initial paperwork and meet the inclusion/exclusion qualifications (to include findings of the physical exam) will be assigned a unique subject number. Subjects will be randomized to treatment group prior to dispensing the test product. 9. Qualified subjects will have their scalp prepared for digital photography and initial measurements done (see Appendix I). 10. Subjects will have the selected test site photographed (see Appendix I and II). 11. Subjects will have ten (10) terminal hairs in the selected test site cut at the base of the scalp and the diameter of the hairs measured (see Appendix III). 12. Subjects will be dispensed a three (3) month supply of the test product (three units of Viviscal or Placebo, as randomized, containing 60 tablets each) and given written and verbal Usage and Lifestyle instructions (see Appendix VII) and a calendar of future visits. Subjects will be instructed to ingest the test product per Sponsor instructions. Usage Instructions: Take two (2) tablets a day, one in the morning and one in the evening; take with water, after food. Subjects will be instructed to return all empty packets and unused test product at Visits 2 and 3. Lifestyle Instructions: Subjects will be instructed to maintain their normal hair care routine. Subjects will be instructed to use the same brand/type of hair care products and maintain the same haircut, color and style for the study duration. Subjects who have color treated hair will also be instructed to have the color treatment performed at the same time interval prior to each visit (ie. If on Visit 1, the color treatment was done one week prior then the color treatment is expected to occur at a similar interval of one week prior to Visits 2 and 3). Subjects will be instructed to come to each visit with clean (shampoo in the morning on the day of the visit) and dry hair. Subjects will be instructed to use a medically sound form of birth control during the study. Visit 2: Month 3 (90 days) ± 1 week (7 days) 1. A clinician will ask subjects if they have experienced any changes in their health or taken new/adjusted current medications since the last visit. If an AE or SAE is reported, the examining Investigator will be informed and the appropriate forms will be completed. 2. The test product will be collected and counted for compliance. Subjects found to be consistently out of compliance will be reminded of the correct usage instructions. 3. Subjects will receive a brief physical exam. The physical will include vital signs (pulse and blood pressure). 4. Subjects will complete the Quality of Life Questionnaire and the Self-Assessment Questionnaire (see Appendix V and VI). 5. Subjects will have their scalp prepared for digital photography (see Appendix I). 6. Subjects will have the selected test site photographed (see Appendix I and II). 7. Subjects will have ten (10) terminal hairs in the selected test site cut at the base of the scalp and the diameter of the hairs measured (see Appendix III). 8. Subjects will be dispensed a three (3) month supply of the test product, (three units of Viviscal or Placebo, as randomized, containing 60 tablets each), and given written and verbal Usage and Lifestyle instructions (See Appendix VII). Subjects will be instructed to ingest the test product per Sponsor instructions. Visit 3: Month 6 (180 days) ± 1 week (7 days) 1. A clinician will ask subjects if they have experienced any changes in their health or taken new/adjusted current medications since the last visit. If an AE or SAE is reported, the examining Investigator will be informed and the appropriate forms will be completed. 2. The test product will be collected and counted. 3. Subjects will receive a brief physical exam. The physical will include vital signs (pulse and blood pressure). 4. Subjects will complete the Quality of Life Questionnaire and the Self-Assessment Questionnaire (see Appendix V and VI). 5. Subjects will have their scalp prepared for digital photography (see Appendix I). 6. Subjects will have the selected test site photographed (see Appendix I and II). 7. Subjects will have ten (10) terminal hairs in the selected test site cut at the base of the scalp and the diameter of the hairs measured (see Appendix III). All primary and secondary parameters will be collected at Visits 1, 2 and 3. Missing data values will be minimized by intensive training of the interviewers in techniques of clarifying answers and checking questionnaires while participants are on-site. When missing values are identified, several approaches such as rescheduled within 24 hours of completion of tests or interviews will be employed to acquire the necessary data. Missing data will be also examined to assess randomness. Descriptive statistics will be obtained for all variables, tests of normality of continuous measures will be made and data will be examined for homogeneity of variance. An appropriate statistical method will be employed to correct for any abnormalities. All statistical tests will be two-tailed. Differences will be considered statistically significant provided a p-value of 0.05 or less is obtained. For each visit, the differences of the two groups from baseline Visit will be tested using analyses of variance with repeated measurements.
