Nothing gives hair a quick-fix moisture boost quite like a quality hair oil, because oils are how the body protects the skin and the hair, naturally. Oils like jojoba and coconut share distinct molecular similarities to the oils of the body.
Remember, many hair care companies lead you to believe you are buying a clean, pure hair oil. In reality, they have filled the bottle mostly with silicones (like dimethicone and cetearyl methicone and which are non biodegradable, and water insoluble which causes them to build up on the hair shaft) and merely added a dash of actual plant nut or seed oil for marketing. Read the ingredients list and question what you are purchasing or using!
