This brush, like many other things, works well when you figure out how best to use it. The bristles do not have little balls on the end to soften the brush from scraping a child's scalp when pressed. So, what my daughter found that worked best for her was to 1) wet the brush. 2) hang her hair down to the side and then brush the tangled area of her hair. This kept the brush from scraping her scalp and let it do its job better. She does like using the brush when she finds a tangle and it's easy for her 8 year old hand to hold. I like being able to just use water and not have to purchase extra detangling spray to use with the brush.
Would I recommend this brush? Yes, I think it's worth a try. But, it may or may not work for you. If a child normally gets mats and tangles on the top of his/her head, I don't think this would be the right brush for the job. If, on the other hand, a child (or adult) can hang their hair off to the side for brushing, this brush can do its job well. It is very easy to use with thick hair because it doesn't scrape the scalp as much (though my older daughter also hangs her hair to the side when using the brush). Just be careful with sensitive scalps and use water with the brush!
Please note that I received a complimentary brush from the company for review.
