I love this product. It's like bootcamp for my hair. I pick up a few bottle per year to whip my hair into shape.
I am a fan of glass packaging. When something is "old-timey" I really like to see it on my bathroom shelf.
I apply this to my scalp like a tonic, and rub it in, and then work it...
This product has done wonders for my hair, especially in winter. My scalp gets very dry during the winter. This product keeps my scalp from getting flakey and too dry. I also think it has helped to strengthen my hair. I seem to get less breakage.
