Horsetail Extract
What is Horsetail Extract?
Horsetail extract is derived from the horsetail plant, scientifically known as Equisetum arvense. This ancient plant, named for its resemblance to a horse's tail, is harvested and processed to create an extract that's commonly used in supplements and personal care products.
It's often included in these products for its traditional uses in supporting hair, skin, and nail health. The extract contains silica, which is believed to promote stronger hair and nails, though scientific evidence on this benefit is not definitive. Some studies provide promising results, but overall, the evidence is mixed.
When you find horsetail extract in a product, it's typically for its purported health benefits, though as with many herbal ingredients, individual responses may vary.
