All you'll have to do is apply a few drops to different sections of your hair, let it sit for about 15-20 minutes after massaging it in, and voila! Follow up with shampoo and conditioner and prepare to be amazed at how freakin' healthy your scalp feels.
Psst, Act+Acre products are vegan, toxin- and chemical-free, and the bottles are made from recyclable plastics that are significantly more eco-friendly.
Promising review: "I never really think about my scalp. It did itch here and there, but nothing major...but throughout the past winter, my scalp has been very dry, flaking, and constantly itchy. Often when I scratch it'll leave flakes under my nails (ew). I tried this product after it was recommended to me by a friend, and oh boy, this scalp detox is life-changing. I have been using it religiously once a week and my scalp has never felt so clean. No more flakes and scratches." —Siyana Tabita
