    my 6 year old daughter won’t use any other brush than this as it goes straight through without hurting which is amazing, highly recommend this brush & it’s all thanks to me purchasing for my mum complete set (dryer) & that’s how my daughter fell in love with the attachment so made us buy the brush. Thanks Mermade Hair!

    Great brush but….

    I like the bristles, the size, the fun pink color, but I wish the handle had some kind of foam grip! My hand slips around too much because I’m tugging at wet hair with a slippery-handed brush and I have to wet my hand to get a good “grip” lol

    Best brush ever!

    It really holds your hair while blow drying. Makes it easy to wrap the hair around the brush!

    I love the size, but I can't use it. The handle is so slippery that it keeps falling in the floor while I'm trying to dry my hair. What am epic fail! They just need to put some rubber on the handle so people can grip it. I know cosmetologists can't use this, it slips right out of their hands. What a waste of money. I am so disappointed 😞 that I can't use this.
