This Review Title is Too sharp for the scalp and the content is: These wooden combs are supposed to be better than the plastic ones. But I had to scrape and see if this was real wood and it is wood. The reason I am not too happy about this product is because the teeth are very sharp and hurt the scalp. I am not too fond of these. I do not know if all the combs are sharp like these or this batch alone. I received four in the package and all are extremely sharp..There are other information for this review, one is This reviewer did purchase it and the other is 2 people think this review is helpful.
