SMELLS AMAZING
The smell literally lasts all day and it smells so good. Seems to do very well as far as skin sensitivity.

Good but not so good
Scent: Mineral Pool, Size: 4.5 Ounce (Pack of 2)
Good soap. If you have sensitive skin or cuts on your hands, it will irritate them. I bought 3 different scents and all 3 made gave my hands inflammation. I really like the smell of them. They make my hands feel soft.

Skin is clean and clear
Scent: Unscented, Size: 4 Ounce (Pack of 6)
I love this tallow soap, highly recommend. I had been making my own soap for a few years but the processes was time consuming, found this tallow soap for a reasonable price and am very happy with it! My skin is clean and clear. No weird smells for the tallow, and good size bars that last us awhile.

Makes my hair shine.
Size: 3.38 Fl Oz (Pack of 1)
This product makes my hair smell good and shiny. You only need to use a small amount for results. I am sure my hair will grow since oil is good for your hair.

Excellent moisturizer! Has a light fragrance and not oily. Only used for a few days so can't attest tolong term benefits.
