This standard size butterfly comb measures 4" and is the most popular of all the sizes. Since this is a 'thick' comb, it is more ideal for women with thick, long, curly, or coarse hair and is great for all styles.
'Thick' combs have more spacing between the teeth to allow a greater amount of hair to flow through with ease. These combs also interlock to ensure a comfortable hold all day.
Also, due to the weaving style of this comb, it will manage a larger volume of hair and keep it in place better.
