Horsetail contains silica which stimulates faster, healthier hair growth. It can be applied topically as a shampoo, conditioner or balm, or it can be taken as a tea or tincture.
Horsetail contains many minerals that include potassium, selenium and manganese. Collagen, a protein found in the bones, skin, cartilage and ligaments, is formed from the silica in horsetail. Together, the silica and minerals improve hair growth, health and elasticity. With regular use, horsetail can also strengthen brittle, damaged hair, giving it a longer appearance. It is important to note that horsetail has an antiseptic property that could cause one's hair to become dry with excessive use.
