Silica and marine extract are sold by the name Viviscal(r).

Self-proclaimed hair loss aid that claims to helps to nourish hair loss and encourages hair growth from inside.

As per MENSCRIPT however they are simply absurd. Based on research studies that were either provided from the company or performed by its employees.

The researchers found that out in the 12 studies that Viviscal refer to at least seven of them were funded by the manufacturer. In these studies, hair loss was typically determined by using unreliable, subjective measures without clinical significance.

They also found that in some of the studies hair loss was measured through a questionnaire in which patients were asked whether they had noticed “less hair loss after using a Viviscal supplement”. MENSCRIPT asserts that such findings aren’t reliable and don’t prove the effectiveness of Viviscal as a legitimate supplement to reduce hair loss.

For instance, they conducted an investigation into the effect that Viviscal on DHT which is a hormone widely believed to be the main reason for male hair loss. According to their research, Viviscal(r) is useless in reduction of DHT. Its impact on DHT is not evident and it is therefore ineffective to stop the loss of hair. Finasteride, on the other hand is a well-known medication to prevent hair loss, decreases DHT by 70 percent. A decrease that results in the complete stoppage of hair loss for more than the 80% of males.
