It didn't really work for me as a facial serum because argan oil is really moisturing, I have normal skin and I live in a humid city. My face looks like I have ran a marathon by the time I have reached my office. But then, it works wonders as a hair serum. Just two drops run through damp hair and it makes my hair manageable in this humidity. And it doesn't leave my hair brittle or weak in the following days, like some serums do. And tea tree oil effectively eliminates many causes of dandruff, with its antiviral, antibacterial and antifungal properties. I only the fact that Ilana makes these combinations that are versatile in use. I just hope Ilana doesn't change the glass dropper to a plastic pump like they did with others. You can't control the amount of product you need with the pump. The glass dropper is an amazing utility.
