Review (4/5): Great for Strengthening Nails and Hair
I put the argan oil in an old, thoroughly cleaned nail polish container and brush it on nightly, while I watch TV. I have VERY weak nails with ridges and this really helps to strengthen them. My nails also tend to split down into the nailbed - doing this helped repair one bad split I'd had for several years .
I also add a bit to my hair conditioner and to my retinol-hyaluronic face cream (Olay type) -really helps to smooth my skin and seems to make the creams go "into" the skin better.
