Great for postpartum hair loss.

Have been using for postpartum hair loss and it works really well. Does not leave hair greasy and smells great. I've been using on my scalp line for 6 months and have a lot of new hair growth. Read more

Good bye sticky-uppy-bits!

Jillyn—July 28, 2025

This stuff smells amazing. The bottle feels luxurious. It keeps you scalp feeling comfy and your hair looking thick and lustrous. But the big surprise? All those little hairs that tend to stick out along the hairline…somehow miraculously gone! Read more

Moisturizing scalp serum

Sarah—November 7, 2025

It’s thick but somehow light, so moisturizing for your scalp! It doesn’t make your hair greasy. It lasted quite a while for the size of the bottle, I’ve purchased this twice now, it’s so worth it. Read more

Effective and not greasy or heavy on curly, knotty, thin hair

Cindy B—July 21, 2025

Love this oil. I have curly, knotting hair that is thin. This oil was fabulous to create a soft style. The hair does still knot, but it seems to be the best oil I've found. Not greasy at all. Read more
