I've used this product for years and have adopted several approaches to using it successfully. I have very fine, easily damaged, color-treated hair that I also straighten on a regular basis. This product helps repair damaged ends and also helps protect my hair from damage when I use a small amount of it on my ends BEFORE heat styling (blow out or flat iron).
When using it as a repairing hair mask, cover your head with a shower cap or plastic wrap and apply low heat with your hair dryer for a few minutes to warm up the product. Then wrap a towel to hold the heat and leave on as long as possible. Rinse for a few minutes with warm water before you apply shampoo and it will be easier to remove. Don't over shampoo or you'll remove the restorative properties of the mask.
I also use it as a pre-heat styling product. Warm product in hands and use only a SMALL amount on ends before blow drying or using flat iron. A very small amount is needed.
Finally, I use it as a finishing product to tame any fly-aways after my blowout. Again, use a very small amount warmed up in your palms. Unlike other oils, it does NOT weigh down hair or make hair look greasy.
The Scent: it reminds me of roasted coffee beans, cocoa, and other toasty-nutty aromas. I like the scent but my husband does not. So it seems people either love it or hate it. I use such small amounts of it when finishing my hair that the scent is not an issue.
