My boyfriend and I both get a monthly birchbox. I needed to shower at his house after we swam in the pool and realized I had run out of my conditioner over there. So, I went to searching through his products, fingers crossed!! I always try to deep condition my hair after I swim in the pool because the chlorine is so rough on it. Luckily, he got a sample of this a couple months ago and had some left. I only used a nickel sized portion and it covered my whole head.. Then it did wonders to my thick, highlighted, normally dry hair!! Plus, I spent like 5 hours saying, "oh my gosh, my hair smells fantastic!!" Needless to say, I bought some that very evening!! In love with it!!
