Exactly what we wanted, we used to buy this from Sally's Beauty Store, but they have stopped carrying it and said they weren't going to be anytime in the future. I am not sure if that is every location, but it was the same story at the three locations near me. So I am glad to have found a place to buy it again.

Intense healing in a convenient jar!

Size: 13.5 Ounce (Pack of 1)

A great healing lotion for all over body application. I like the product being in a jar so there is no problem getting the lotion out of a bottle making this a very wise economical choice. A 72 hour intense healing lotion providing a long lasting healing experience. Highly recommended.

The texture is rich but still absorbs nicely into the skin, and a little goes a long way. I NIVEAs

deep hydration and works especially well for very dry skin. The formula feels rich and nourishing but still absorbs nicely without feeling greasy. After applying it, my skin feels soft, smooth, and comfortable for hours. I also love that it contains ingredients like glycerin, Pro-vitamin B5, and niacinamide to help repair and protect dry skin.
