Two words “oil” and “mask” what I hear, “locked in moisture and happiness”. The Dove Advanced Hair Series Pure Care Dry Oil Treatment Mask is all its cracked up to be and I mean ALL! It deeply nourishes and the Macadamia Oil smalls amazing! I used it as a pre-mask because I really wanted to see whether it can be used as both, and surprise, surprise, IT CAN! I left it on for 20 minutes before I shampooed and conditions with their Oxygen Moisture Series. My hair felt like it had new life breathed into it (excuse the air pun). I would suggest you use this mask once a week, I have a lot of hair, so it tends to get heavy if I use a mask, so I try not to overuse it.
