Mammoth Essential Oil

SKU: 38-50021

$42

Our Mammoth Multi-Purpose Oil blends organic argan and jojoba oils to create an all-natural moisturizer suitable for face, hair, and body that is light, non-greasy, and quickly absorbed by skin and hair.

Our Mammoth scent derives from the environs around Mammoth Hot Springs, an active geothermal feature of otherworldly travertine terraces and pools, found on the northern edge of Yellowstone National Park. Opening with mountain hay-grass and fresh citrus, our Mammoth fragrance then mellows into a heart of living sagebrush and cedarwood with earthy undertones; it's a fragrance for people who love the aroma of the great outdoors. Caswell-Massey bottled that magical moment of melting snow, wet earth, and new blossoms.

Fantastic!

I started off with Canyon and Tower Fall but Mammoth is my new favorite! The oil is perfect for dry legs or fly away hair. Put a little on your arms and hands before going to sleep and you will have sweet dreams. Have already ordered another bottle.
