I've been using this since I first got it in my box about 8 years ago. It makes my hair super soft and also comb-able even when I destroy it with bleach. I would recommend it to almost anyone. I've tried a lot of other hair balms and leave-in conditioners from birchbox since, but nothing leaves my hair feeling/looking as silky.
My only complaint is that the way the bottle is designed, as it gets empty it gets really hard to get the balm out. I have to balance it upside down then unscrew it and bang it on my palm to use it all up. I wish it either had was shorter/wider mouth so I could stick my fingers in or a squeeze design so i could squeeze the last portion out. For $30 I feel like I should be able to use all of it easily lol.
