Nettle Root Extract
Nettle, or stinging nettle, is a shrub that comes from northern Europe and Asia. Stinging nettle leaf has a long history of use for hair, skin and as a vegetable dating back to ancient Greek times.
Not only does nettle help in combating hair loss, it also helps in hair re-growth. Nettle leaves are rich in silica and sulphur. This helps in making hair shinier and healthier. Rinsing hair with nettle extracts and water results in re-growth of lost hair and also helps in restoring the original hair colour.
Nettle is especially effective when used in combination with Beta-Sitosteral.
