Shampoo with hyaluronic acid for added volume. - Brand: Kérastase - Product Name: Bain Densité - Volume: 1000ml - Features: Shampoo that adds volume to hair - How to Use: For professional use only - Ingredients: Hyaluronic acid, gluco-peptide Purchased in September 2025 at a beauty salon. Retail Price: ¥11,000 I have been a long-time Densifique user. I have been using Densifique for many years. Due to the effects of PM2.5 and yellow sand, my skin became unstable, and I suddenly developed an allergic reaction. I stopped using it after using about a third of the bottle. I have decided to sell it as I am monitoring my skin condition. I am decluttering and starting fresh, and I would like someone who wants to use it to take advantage of it. If you are concerned about hygiene, please refrain from purchasing. It will be shipped in simple packaging. Please use it if you would like to. The included pump is a replacement from the previous purchase of the same shampoo. Please note that it is a used item and may have some minor scratches. Thank you for looking.
