Scientific Study #1
Treatment of Alopecia Areata, Alopecia Totalis and Alopecia Universalis with Oral Viviscal® for 12 months
Swedish Alopecia Association, administrated by B. Prästbacka (chairman) and Patricia Brosdotter-Johansson (vice chairman)
The study was clinically monitored by M. Majass (md) and O. Puuste (md)
Department of Dermatology, Central Hospital, Tallinn, Estonia, 1994
Summary
Altogether 97 members of the Swedish Alopecia Association (RFH) with either alopecia areata, alopecia totalis or alopecia universalis volunteered to participate in a 12 months study to evaluate the effect of oral Viviscal® on regrowth of scalp hair. Thirteen patients withdrew after 3 - 4 months because of lack of effect of the treatment. The remaining 84 patients fulfilled the treatment and were therefore evaluable.
Fifty of these had alopecia areata, 12 alopecia totalis and 22 alopecia universalis. They all took two tablets of Viviscal® daily for 12 months. Before the study, after 6 and 12 months they fulfilled a questionnaire regarding the start of regrowth of scalp hair and the estimated area of the scalp with regrowth of permanent hair. In the areata group regrowth of permanent hair started to appear after approximately 6 months in 46 patients, in the totalis group in 10 patients after 4 months and in the universalis group after 5 months in 7 patients. After 12 months 7 patients in the areata group (14%) showed complete regrowth of hair, 27 patients estimated a regrowth of 70 - 95%, 10 a regrowth of 50 - 65% and 6 a regrowth less than 50%. In the totalis group 3 patients had a complete hair regrowth, 3 a regrowth of 70 - 95%, 4 a regrowth of 50 - 65% and 3 a regrowth of hair less than 50%. In the alopecia universalis group one of the patients reported complete regrowth of hair, 4 had a regrowth of 70 -95% and one a regrowth of 50 - 65%, while 16 had less than 50% regrowth of scalp hair. Better nail growth was reported by all patients with weak nails prior to the study.
Overall 34 patients (68%) of the patients in the alopecia areata group, 6 of the patients (50%) of the patients in the alopecia totalis group and 5 patients (23%) in the alopecia universalis group were highly satisfied with the treatment results, while 10 (20%), 4 (33%) and 1 (5%), respectively estimated the end result as good.
There was a significant correlation between the treatment results and the type of alopecia, but no significant correlation between the sex and age of the patients or duration of hair loss could be observed. No adverse reactions or unexpected events were reported by the patients.
Scientific Study #2
Treatment of Alopecia Areata and Alopecia Totalis With Viviscal® (Special Marine Extract Compound)

Summary
Twenty patients with alopecia areata (mean duration 9 years) and 20 patients with alopecia totalis (mean duration of 7 years) were treated with 2 pills of Viviscal® Liniment once daily and Viviscal® shampoo 2-3 times/week for eight months.
Viviscal® is a preparation containing mainly compound of marine extract and colloidal silicic acid. Both group included 10 females and 10 males. All patients had earlier received topical steroids and 15 had had been treated with systemical corricosteroids. Most of them had also been treated with topical minoxidil and photochemotherapy. Seventeen of the patients with alopecia areata (85%) were completely cured and two showed significant improvement. One of the patients in this group deteriorated during the treatment period. Five (25%) of the patients with alopecia totalis were completely cured and four (20%) showed significant improvement, while 11 patients developed only minimal vellus hair.
This promising study showed that Viviscal® is a further complement to the rather short list of remedies which alter the clinical course of alopecia areata and alopecia totalis.
Scientific Study #3

Summary
A controlled, randomized, double-blind, parallel-group study compared the effects of Viviscal® (a new food supplement incorporating special marine extracts and a silica compound) with those of a fish extract in the treatment of young males with hereditary androgenic alopecia. The pretreatment histological diagnosis was alopecia with a mild to moderate perifollicular inflammation zone. The study consisted of 20 subjects who received two tablets of Viviscal® once daily and 20 who received two tablets of fish extract once daily for 6 months.
The mean patient age and mean duration and severity of baldness compared well between the two groups. Most patients had been treated with long-term topical 2% minoxidil for 1 year or more prior to the study. At baseline and after 6 months' treatment, a biopsy was taken for histological examination. A non-vellus hair count was performed at baseline and after 2, 4 and 6 months. In the fish extract treatment group three patients withdrew from the study before the fourth month due to lack of therapeutic effect. After 6 months' treatment, patients receiving Viviscal® showed a mean increase in non-vellus hair of 38% compared with a 2% increase in the fish extract treatment group (P<0.0001). In the Viviscal® group, 19 (95%) subjects showed both clinical and histological cure, whereas none treated with fish extract showed any clinical or histological difference after 6 months' treatment (P <0.0001). In both groups, a minimal decrease in the erythemal index was observed.
In conclusion, Viviscal® appears to be the first highly active treatment for androgenic alopecia in young males.
Pilot Study
Latest study finds Viviscal dramatically reduced hair shedding over a 10 week period
Summary
A pilot study conducted by Thomas J. Stephens & Associates Inc. in the US showed that Viviscal was well received by the participants and the analysis of hair counts showed a mean reduction of hair loss of 46%. The participants included women of Caucasian, African American, Asian and Hispanic ethnicities with the average age being 35.
• 81% saw a decrease in thinning hair on an average day
• 75% saw an increased thickness in the body of their hair
• 75% saw an increase in overall hair volume
