Creative Hair BrushesTriangle Ceramic & Ionic CR200 PRO, Large 3.0"

Q: I have short hair cut in a bob an inch past my ears-- What size is recommended?

I would not get any bigger than 1.5

Q: What is the difference between the 3 styles? my hair is less than shoulder length so i was thinking of buying small but it only comes in cr50.

CR-50 is the small brush. And you can get get a good curl flip underneath if you want, but if you want total straightening, you should probably get the Cr-100 which is the medium brush. The large brush would probably be too large.

Q: Are the bristles synthetic or a combination synthetic & boar hair?

They are not boar hair but please contact the manufacturer for this type of question. In the description it tells us ion bristles. Whatever it is, it’s made to withstand heat. Sorry I can’t be of further help.
