My go-to conditioner

"This conditioner checks all my boxes: vegan, cruelty-free, comes in a refillable pouch (less plastic waste), and works great. It tames my frizz and fly aways without weighing my hair down. Rinses clean. The smell is mild but pleasant. And the price is reasonable. No complaints."

Fantastic stuff!

"There are many things I love about this conditioner: Yuzu scent, effective conditioning. I don't need a lot of conditioner to get the job done. Also love I can buy refills and not multiple bottles. For me, this has been a miracle product- effectively detangling my wavy hair without dumping tons of products on my hair. Love it!"

— Barbara T. (5/5)
