Talking about brush may seem a little confusing, because there are two types widely used, but they do not have the same function. In fact, the flat brush and styling brush complement each other.
The flat hair brush, as the name implies, is not circular and has bristles only on one side of its base. Its bristles are more separated and thicker, and usually have rounded tips due to direct contact with the scalp.
The function of this kind of brush is to comb and untangle the hair. It can be used several times a day, both on dry and wet hair.
Its usefulness is very similar to that of a comb, since it is also widely used to untangle the strands, although it does not always please people who have thinner hair.
