Humans usually brush their hair to:
* Remove tangles and knots: This makes hair easier to manage and style.
* Distribute natural oils: Brushing helps spread the oils produced by the scalp along the hair shaft, keeping it moisturized and shiny.
* Stimulate blood circulation: Brushing can help promote blood flow to the scalp, which may benefit hair growth.
* Remove dirt and debris: Brushing can help remove dust, pollen, and other particles that may accumulate in the hair.
* Improve the appearance of hair: Brushing can help smooth down flyaways and create a more polished look.
So, if you have hair, brushing it is usually a good idea!
