I am obsessed with the scent of this shampoo. With any hair product, the first thing you notice is definitely the way it smells, and the smell of the Degrease Moisture Control is absolutely gorgeous. This shampoo contains lemon, rosemary, and basil, and that is definitely the smell that comes across. It's a very herbal, soothing scent that reminds of the products used in nice spas. It's odd - I find the scent relaxing at night thanks to the rosemary, and invigorating in the mornings thanks to the lemon. It's such a unique, beautiful smell.But the scent alone isn't why I adore this shampoo. While a lot of degrease shampoos leave hair incredibly dry, even when you follow up with a conditioner, this product leaves hair soft and vibrant. One of my biggest priorities when styling my hair is achieving volume at my roots, and this shampoo does an amazing job of that, even though it isn't sold as a volumizer. However, by truly removing excess product build-up and oil at the scalp, it allows my hair to no longer be weighed down at the root, and to have a lot more volume.This shampoo works a little differently than normal shampoos, and you have to make sure you read the directions, which tell you to let it sit on your scalp for about three minutes. It tingles a little bit, but by no means stings or irritates. My favorite trick when using this shampoo is to copy what stylists in salons do when they prepare your hair to be washed. Before you get in the shower, brush your hair thoroughly, and give yourself a light scalp massage with the pads of your fingers. This breaks up the oil and dirt at the roots and allows you to really thoroughly cleanse your scalp when you shampoo. Between using that trick and this shampoo, my scalp has never felt cleaner, and the health and vibrancy of my hair at the roots is absolutely stunning.This shampoo is a perfect solution for anyone with an oily scalp. It's incredibly effective, but also very gentle. My sister has a very dry hair type and no issues with oil at the roots, but she actually likes to borrow this as a once-a-week clarifying shampoo. I think it is perfect for that, and can be used to deeply cleanse the scalp, even for those who only need such a thorough cleansing once a week or month.
