Yves Rocher hair vinegar

Yves Rocher Hair Vinegar, Raspberry scent... I use this product often because I have an oily scalp. After using it, my scalp feels squeaky clean and my hair is smooth. However, using this delays my hair from getting greasy by a day. The scent is raspberry, but it fades quickly. The downside is that it is a bit inconvenient to use. It would be easier to apply to the scalp if the opening were pointed, but the flat cap makes it difficult to control the amount. I wish they would change the packaging.
