Its pretty simple. I have had this brush a decade or more. I loved it but did not make it my main brush till my hair became thicker and more tangled due to it being long. I was only using a wide tooth combfor awhile till I pulled out this brush-its the only brush I can get through my hair feeling it goes all the way through and without making it frizzy.
The bamboo bristles are long, smooth, round tipped and the rubber base gives the bristles a flexible range of movement making it most comfortable.The round tips feel great on the scalp. The wide spacing of the bristles make it great for curly hair that loves to frizz with a regular brush ( my other brushes are Mason Pearson.. fantastic too.. but dont go through really thick curly hair as well)
I love it whether my hair is long or short.. but its a must havewhen its long and I am trying to keep the curls from frizzing and feel a nice massage.
Hope that helps!

WIDU "Bamboo" Bristle Hair Brush
This wood comb is awesome.I'm very pleased using it because is natural and it is not braking the hair like plastic products.I can't wait to purchase some wood hair brushes.
This Widu small pocket comb is well-crafted and finished, convenient to use (I have long straight hair), but beware that it can still create static in your hair. Somehow I was under the impression that wood combs and brushes don't create static, but obviously I was mistaken. 
This comb is of very good quality. No sharp areas, all smooth wood. It does not scratch your head and lies very good in your hand. It is a pleasure to use it.
Very pleased with this product! After coming across it in a printed catalog, I decided to order one (more cheaply) through Amazon. This is the brush I have been dreaming of!!! It really massages my scalp (unlike the 4 other brushes - boar bristle and ball-tip bristle), moves through tangles easily (I have thick, fine hair), and makes my hair look great after brushing. I will be buying more of these for Christmas gifts!
