My itchy scalp
Maybe I was expecting miracles, but it didn’t do as well as I thought it did. I’m still using it hoping that I was expecting too much too soon, but it’s been almost a month now and my head is still itchy and scaly.

Husband’s eczema is slowly going away
Size: 3.3 Ounce (Pack of 1)
These reviews aren’t hype, the product really is that good!
I didn’t think eczema could be improved by something as simple as changing to bar soap. A gentle eczema friendly one at that! My husband loved this soap immediately and he’s one of those crunchy/almond moms (lol). He uses it in the shower and he doesn’t want to share the bar with me 🤣 it smells SO good and moisturizes and cleans so well without drying. He is noticing his eczema on his hands is improving and what was red and lumpy scabbing is now smooth scabbing with almost no redness. I have it on auto buy now. I plan to use it on my sink too once I finish my bottle of liquid soap! 5 stars.

Helpful gentle soap
Size: 3.3 Ounce (Pack of 1)
This soap is amazing for our sensitive skin. No more flare ups, even in winter. The smell is not strong and it lasts a solid month of every other day use. Its gentle enough that I’ve used it with two newborns.
