Bottom Line
Curlsmith - Bonding Oil is a moisturizing and repairing hair oil that works well for thick, curly hair in dry climates. It provides moisture, reduces frizz, and adds curl definition. However, it may not be suitable for those with fine or thin hair, as it can make it greasy or weigh it down. The scent is pleasant, but some users may not prefer it. Overall, it is a good alternative to Olaplex's No 7 bonding oil at a better value.
