I have been using this product on my hands, particularly my nails as of late with the cold weather they have become rather brittle, within a few days of using this i have noticed a huge difference in my nails already, they are much stronger and are more white in colour. My hands through the winter months also became rather dry and the argan oil has helped stop the dryness. The dropper makes things easier as you don't end up wasting excess product, the oil absorbs quickly and can be easily wiped away if there is any excess oil left after 5-10 mins. Will be trying it on my hair this evening as have been suffering with dry scalp recently, but i have no doubt that this will help aid that as well.
