This Review Title is Good quality but suitable for thick substance and the content is: I use these for scalp toner but the comb teeth too wide for runny liquid like a toner, it dispense the toner continuously spreading the toner not only on scalp but hair too. It will be great if the teeth dispense the liquid only with gentle pressure on the bottle. I will look for another bottle for my purpose..There are other information for this review, one is This reviewer did purchase it and the other is 6 people think this review is helpful.
