Review: Good Brand, Good Quality, Good Price - Have been purchasing through desertcart for a little while now, cannot find at the local drugstores ( CVS, Rite Aid, Walgreens ) and at a good price. I appreciate you keeping this in your inventory and it Ships quickly. Review: Excels At Adding Volume To Fine Hair - I have fine baby-like hair. This is the only shampoo I've found that actually increases volume. I swear by it and have used it for years. It has become somewhat hard to find, though, and it is certainly not cheap. Beats the price of a lot of these high end products that claim to do the same thing. I'll keep buying it as long as I can still get it. ## Features - PROTEINFUSION: With Elastin and Green Tea - an innovative blend strengthens and thickens each hair strand, leaving you with noticeably fuller, more voluminous locks - WEIGHTLESS FORMULA: Lightweight lather gently cleanses and nourishes without a hint of heaviness, allowing your hair to soar to new heights (literally) - VITAMIN INFUSION: Features Panthenol (Vitamin B5), adds essential moisture and shine, preventing your hair from becoming brittle or frizzy - SALON-QUALITY RESULTS AT HOME: Experience the professional-level difference, minus the hefty price tag; Deliver volume and shine that lasts - SUITABLE FOR COLOR-TREATED HAIR: Won't strip your color or leave your hair feeling dull; Consider it your color-safe confidante! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00GMQ3FH6 | | Active Ingredients | Green Tea Extract, Green Tea, Panthenol | | Age Range Description | Adult | | Age range (description) | Adult | | Brand | Nexxus | | Brand Name | Nexxus | | Customer Reviews | 4.6 out of 5 stars 146 Reviews | | Hair Type | Fine | | Hair type | Fine | | Item Dimensions | 23.5 x 6.7 x 6.7 centimeters | | Item Form | Liquid | | Item Weight | 13.5 Ounces | | Item form | Liquid | | Liquid Volume | 13.5 Fluid Ounces | | Manufacturer | Nexxus | | Manufacturer Part Number | 10007160 | | Material Type Free | Silicone Free | | Material type free | Silicone Free | | Model Number | SG_B00GMQ3FH6_US | | Number of Items | 3 | | Other Special Features of the Product | Not Tested On Animals | | Product Benefits | Cleansing, Color Protection, Nourishing, Replenishing, Shining | | Scent | Green Tea | | Scent Name | Green Tea | | Suitable Hair Color | All Hair Colors | | UPC | 605592140532 | | Unit Count | 40.5 Ounce | ## Product Details - **Age range (description):** Adult - **Brand:** Nexxus - **Hair type:** Fine - **Item form:** Liquid - **Scent:** Green Tea ## Images ![Nexxus Shampoo Diametress Volumizing 13.5 Ounce (399ml) (3 Pack) - Image 1](https://m.media-amazon.com/images/I/51wEzNrij9L.jpg) ![Nexxus Shampoo Diametress Volumizing 13.5 Ounce (399ml) (3 Pack) - Image 2](https://m.media-amazon.com/images/I/61DQ1Y+g7FL.jpg) ![Nexxus Shampoo Diametress Volumizing 13.5 Ounce (399ml) (3 Pack) - Image 3](https://m.media-amazon.com/images/I/61NAJSfxedL.jpg) ![Nexxus Shampoo Diametress Volumizing 13.5 Ounce (399ml) (3 Pack) - Image 4](https://m.media-amazon.com/images/I/81FXeItnYJL.jpg) ![Nexxus Shampoo Diametress Volumizing 13.5 Ounce (399ml) (3 Pack) - Image 5](https://m.media-amazon.com/images/I/71zo5UBddJL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good Brand, Good Quality, Good Price *by G***T on 25 May 2025* Have been purchasing through Amazon for a little while now, cannot find at the local drugstores ( CVS, Rite Aid, Walgreens ) and at a good price. I appreciate you keeping this in your inventory and it Ships quickly. ### ⭐⭐⭐⭐⭐ Excels At Adding Volume To Fine Hair *by R***G on 24 October 2025* I have fine baby-like hair. This is the only shampoo I've found that actually increases volume. I swear by it and have used it for years. It has become somewhat hard to find, though, and it is certainly not cheap. Beats the price of a lot of these high end products that claim to do the same thing. I'll keep buying it as long as I can still get it. ### ⭐⭐⭐⭐ Leakage.. Further Review-Lost about one third per bottle *by F***Y on 15 August 2023* All 3 bottles leaked. Not a lot lost but real messy when I opened the inside packaging. Would suggest taping the tops. All the leakage was from the top screw on cover. The product is a great product and I didn’t lose a ton of the shampoo but I’ve received this product in the past and the taping prevented this problem. ## Frequently Bought Together - Nexxus Shampoo 13.5oz Diametress (Volumizing) (3 Pack) - Nexxus Humectress Ultimate Moisturizing Conditioner 1 lt - Nexxus Humectress Conditioner For Dry Hair Ultimate Moisture With Caviar & Protein Complex 13.5 oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/278990207-nexxus-shampoo-diametress-volumizing-13-5-ounce-399ml-3-pack](https://www.desertcart.us/products/278990207-nexxus-shampoo-diametress-volumizing-13-5-ounce-399ml-3-pack) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-02*
