Too sharp for the scalp [SEP] 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.
