Horsetail hair oil is an oil derived from the horsetail plant, also known as Equisetum arvense. The plant is known for its high silica content, which is believed to promote healthy hair growth and improve hair texture.

Horsetail hair oil is typically made by steeping horsetail in a carrier oil, such as coconut oil, for several weeks to extract the beneficial compounds. The resulting oil can be applied to the hair and scalp to nourish and strengthen hair.

While there is limited scientific research on the benefits of horsetail oil for hair, some people claim that it can improve hair health and prevent hair loss. However, it is important to note that more research is needed to confirm these claims and to determine the optimal usage of horsetail oil for hair care.

It is always recommended to do a patch test before using any new product, especially if you have sensitive skin or allergies. If you experience any adverse reactions, discontinue use immediately and seek medical advice.
