What Is Silica?
Silicon dioxide, also known as silica, is an oxide of silicon, a non-metallic chemical element. Silica combines silicon and oxygen and is primarily found in green leafy plants and available in oil, gel, and supplement forms.
Our body needs silicon in trace amounts for collagen synthesis and improving skin strength and elasticity. Silicon helps prevent hair fall and maintains hair shine (1). No scientific evidence supports the claim that silica can promote hair growth. However, silica supplements may help improve your hair health. In the next section, letâs take a look at the benefits of silica.
Benefits Of Using Silica For Hair
1. May Prevent Hair Loss
Silica may not directly influence your hair health. However, studies suggest that silicon content in the hair is crucial for maintaining its strength and may prevent hair loss (1). You may take silica supplements to improve the silicon content in your hair and prevent hair thinning.
2. Improves Tensile Strength
A study demonstrated that choline-stabilized orthosilicic acid (ch-OSA) supplements improved hair structure and tensile strength in women with fine hair. Orthosilicic acid is an amorphous form of silica and improves hair elasticity and break load, resulting in thicker hair (2).
Now that you know the benefits of silica supplements for hair, let’s discuss the right way to use silica supplements.
How To Use Silica Supplements
The best way to use silica for maintaining hair health is by taking oral supplements. Silicon or silicon dioxide supplements are available in pill, powder, and gel forms. You may consume any of them. However, before taking supplements, consult a doctor to determine if your body has silicon deficiency. Do not self-medicate.
You will also find shampoos, conditioners, and other hair products containing silicon. However, the efficacy of topical silicon is not studied. You may or may not get any results after using silicon-rich hair products.
The supplements will work only in the right dosage. In the next section, find out how much silica supplement you may consume.
Dosage Recommendation For Silica Supplements
Silica supplements are used for managing issues related to the skin, joints, bones, and hair (1). The recommended dosage may differ, depending on the issues. Therefore, consult a doctor for the right dosage.

Is Silicon Dioxide Safe To Consume?
There is no evidence that oral silica can cause any health hazard or side effects. The FDA considers silicon dioxide or silica as a safe food additive (3). However, the European Food Safety Authority (EFSA) raised concern over the use of nano silicon dioxide smaller than the nano threshold of 100 nm (4). EFSA further urged the European Union to regulate the use of nano silicon dioxide until further research is conducted to evaluate its health implications.
To avoid any side effects, consult a doctor before using silica supplements.
Silica does not promote hair growth. However, silica supplements may strengthen the hair, prevent breakage, and minimize hair fall. Taking oral supplements is the best way to use silica for maintaining your hair health. However, consult a doctor for the recommended dosage.
