About
The Viviscal Extra-Strength formulation is an oral food/dietary supplement specifically designed to promote hair growth for women suffering from temporary thinning hair. It does not contain hormones or drugs and has been marketed in Europe for over 15 years. Viviscal Extra-Strength is marketed as Viviscal Maximum Strength in some other territories.
The hypothesis of this clinical research study is that the ingestion of Viviscal Extra-Strength over a three (3) month period will strengthen and promote the growth of terminal hairs in female subjects, ages 21-65 years of age with self-perceived thinning hair associated with poor diet, stress, hormonal influences or abnormal menstrual cycles when compared to using the placebo tablet.
Full description
The key ingredient of Viviscal Extra-Strength formulation is AminoMar C™ marine complex, Equisetum arvense sp. (horsetail), containing a naturally occurring form of silica), Malpighia glabra (acerola cherry) which contains Vitamin C, Biotin and Zinc. 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 many ways over several months of use to improve the appearance of thinning hair.
Ingestion of Viviscal Extra-Strength over a three (3) month period will strengthen and promote the growth of terminal hairs in female subjects, ages 21-65 years of age with self-perceived thinning hair associated with poor diet, stress, hormonal influences or abnormal menstrual cycles when compared to using the placebo tablet. The primary endpoints will be individual hair counts and favorable analysis using the Nikon CoolPix 4300 with 3GEN Dermlite Foto37 for phototrichogram analysis at the end of the three (3) month period. The secondary endpoints will be statistically significant decreased hair shedding counts with hair washing, favorable improvement in terminal hair diameter measured by the Dino-Lite Digital Microscopic and positive feedback on the Quality of Life and Self-Assessment questionnaires after three (3) months of Viviscal Extra-Strength 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 60. 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 Investigator. 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 Viviscal Extra-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.
Visit Procedures Pre-Study Procedures
Visit 1: Baseline, Day 0
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 Visit 2.
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 Visit 2).
Subjects will be instructed to come to each visit with clean (shampoo must be done 24 hours prior to 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)
All primary and secondary parameters will be collected at Visits 1 and 2. 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 but other p-values may be evaluated on a case-by-case basis. For each visit, the differences of the two groups from baseline Visit will be tested using analyses of variance with repeated measurements.
