I went to get my hair weaved and cut today. My hairdresser used this brush to blow dry and after I saw the results I wanted to get it. This is the first time I've spent money on a brush bought from a salon. I always just buy the drugstore brushes. This one was $30! I can't believe I bought it. It better be good for that price! My hairdresser said that it will last a long time. It's called Bio Ionic and it's suppose to add shine, tame frizzies and control static. It's suppose to be good for the hair and minimize breakage and seal spilt ends. I didn't think a brush could do all that and I'm still sceptical but my hair looks good so I wanted to try it. We will see how I do when I use it vs my hairdresser. I can never get my hair to look the same at home as it does at the salon. I guess that's why I'm not a hairdresser and I pay her to do it!
