I love the way the shampoo cleans and hydrates my hair. A little goes a long way with this shampoo. You only have to use minimal amounts of the product for a full effect. I also like that the shampoo doesn't overwhelm you with heavy perfumes. The scent is clean and refreshing, and the green tea makes a difference with the health of your hair. Effectiveness For oily hair, I would recommend only using a very small amount because that is all you need. If you use too much of this product, it can make your hair more oily if you already have an oily hair type. I like the way this shampoo makes my hair have more volume and how it makes my hair feel refreshed. Scent The scent of this product is made to lightly refresh your hair and not to overpower your senses. If you are more sensitive to other product's scents, then I would recommend trying this shampoo. The green tea makes a difference with the health of your hair, and gives the shampoo a clear scent.
