Review title is Amazing time saver! Must have for wavy hair! [SEP] Amazing! I have struggled with my thick, wavy hair my entire life and had basically given up on straightening it because it took WAY too long. But this brush straightened all my hair in about 10 minutes, my arms did not get tired and sore, and I was not all sweaty and annoyed when I was finished. This is what success looks like, people! I went and ordered a second one for my teenaged daughter who was cursed (blessed?) with the same texture of hair as I have because this brush is so amazing. Highly recommend it to anyone with hair that is not curly enough to wear it curly, but too curly to wear it straight.
