Silica, which is short for silicon dioxide, is a mineral that can help hair growth. It is already found in the body, but more silica can be obtained through certain foods as well as in other forms to enhance hair quality.
Silica is a common component of the body. It is found in connective tissues, muscle tissue, bone, nails and hair. Silica helps strengthen hair and makes it less likely for hair to become brittle and develop split ends.
Silica helps retain moisture in hair, creating shinier strands. It helps also strengthen hair and prevents or reduces hair loss.
Silica's effects won't be visible overnight. It may take up to two or three months after the start of supplements for any visible effects to become apparent. After that, hair growth can be maintained through regular ingestion of silica.
Silica can naturally be found in raw oats, wheat, whole grains, rice, alfalfa, barley, onions, millet, beetroot and leafy green vegetables.
In addition to eating foods that contain silica to assist with hair growth, people can take it as a supplement.
