So I have Birchbox Beta and have the option to be sent personalized samples, choose a product, skip a product, or choose from a pre-set box. I noticed the Spotlight on Radiance box featured this product and I figured since I've been wanting to try it I would choose that box, even though I didn't need or want other items in it. I was definitely surprised when I opened it and saw that they had sent the 50ml bottle instead of a teeny tiny sample. This bottle sells for $30! So right there, this Birchbox was already worth it two times over.
As for the product, it definitely lived up to its hype. I apply it to towel dried hair befor I use my Amika thermal smoothing brush and my hair comes out soft and shiny. And since you only need a few drops, this sample will last me forever! Thanks Birchbox!
