Nettle is one of the oldest treatments for combating hair loss and it also helps in hair re-growth. Nettle leaves are rich in silica and sulphur. This helps in making hair shinier and healthier. The leaves have anti-inflammatory properties to help reduce inflammation in the scalp and promote a healthy head of hair. Nettle extract can block the production of DHT by reducing the production of the 5-alpha-reductase enzyme. It has the ability to stimulate blood circulation.
