What material is highly recommended for hairbrush bristles?

Natural bristles are highly recommended for hairbrush bristles due to their ability to provide a number of benefits for both the hair and the scalp. These bristles are typically made from materials such as boar hair, which can help to distribute the hair's natural oils along the strands. This distribution enhances the hair's shine and overall health, making it less prone to damage.

Additionally, natural bristles tend to be gentler on the scalp compared to synthetic options. This gentleness reduces the risk of scratching or irritation, making it suitable for delicate scalps. Furthermore, natural bristles have a certain flexibility that allows them to glide smoothly through the hair without causing as much friction, which can lead to breakage.

In contrast, synthetic fibers and plastic bristles can sometimes create static electricity and might not have the same ability to condition the hair. Metal bristles, while they may be durable, can be harsh on both the hair and scalp, potentially leading to snagging and breakage. Therefore, the choice of natural bristles is particularly advantageous for achieving healthier-looking hair and maintaining scalp integrity.
