Great for thin loose curls
Ive used this in my 4 year old daughters loose curls for a couple years now and its a good less toxic, less ingredient option. Smells nice and works pretty well. I don’t care for the containers it comes in because if they stay very wet in the shower they start to get moldy and if you aren’t careful you can pour way to much out but I still keep re-purchasing.

Smells bad
This product smells like acetone, which makes me believe that the ingredients might have gone bad. The matching shampoo smells good and no issue there but this conditioner is questionable.

Love it!
I've always been a fan of Babo's amazing sunscreens, so when I heard they were diving into hair care, I was intrigued. And let me tell you, their natural conditioner doesn't disappoint! It works like a charm, leaving my hair silky smooth. Plus, knowing Babo's dedication to eco-friendly sun protection, I'm all in for this refreshing addition (and packaging) to their lineup. It's a win-win for my hair and the planet!

Very liquidy
Spilled from the spout because it was too liquidy for a conditioner- more of a body wash consistency.

It’s not for dry curly hair
Very good non-toxic choice but it does not support dry curly hair.
