Review: This works!!! Worth every penny! - My hair is thinning badly due to low iron and a 100lb glp-1 weight loss. It has been a very depressing time. My hairdresser said a lot of her clients were having luck with this - and WOW! It’s amazing. My hair feels healthier and is definitely thicker, enabling me to style it to cover the thin or bald areas. Combined with a Nutrafal regimen, I have had real growth and am finally feeling better about myself. Give it a try if you suffer with hair loss like me! Review: This works - It's a great product. I find it really works. It's unscented. My hair is thicker. I would definitely buy this again. Update...it's full of caffeine which I am allergic to. Made me very ill. Buyer beware. There should be a warning ⚠️ on the label!!! ## Features - manufacturer: Nioxin - Item Trademark: NIOXIN - Style: Diamax Advanced, 3.38 oz. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B086G3LFD1 | | Best Sellers Rank | #227,433 in Beauty ( See Top 100 in Beauty ) #1,797 in Hair Regrowth Treatments | | Brand | NIOXIN | | Brand Name | NIOXIN | | Customer Reviews | 4.4 out of 5 stars 1,022 Reviews | | Hair Type | Thin | | Hair type | Thin | | Item Form | Serum | | Item Volume | 0.34 Fluid Ounces | | Item Weight | 3.4 Ounces | | Item form | Serum | | Item weight | 3.4 Ounces | | Manufacturer | Nioxin | | Manufacturer Part Number | 3614228816113 | | Model Number | 3614228816113 | | Number of Items | 1 | | Recommended Uses For Product | Professional Salon & Spa | | Recommended uses for product | Professional Salon & Spa | | Scent | Unscented | | Scent Name | Unscented | | Unit Count | 3.38 Ounce | ## Product Details - **Hair type:** Thin - **Item form:** Serum - **Liquid volume:** 3.4 Fluid Ounces - **Scent:** Unscented ## Images ![Diamax Advanced, 3.38 oz - Image 1](https://m.media-amazon.com/images/I/61A8UgXX8bL.jpg) ## Questions & Answers **Q: Does the nioxin diamax get combed thru the hair or just applied at scalp?** A: I am happy to answer this for you today.

My hair were falling out like crazy but after using this product it stopped and I actually have lots of baby hair. I thought the product will be oily but it is more like just a liquid and it doesnt leave hair greesy. ## Frequently Bought Together - Nioxin Density Defend Diamax Advanced Hair Thickening Serum With Caffeine, Niacinamide & Panthenol For Thicker, Fuller-Looking Hair 3.38 Fl oz - Nioxin Night Density Rescue Serum | Overnight Hair Thickening Serum | Protects Against Hair Breakage | Intensive Treatment with Oxydine | 2.4 Fl oz. - Nioxin Hair Booster Serum | Advanced Leave-In Hair Treatment| Strengthens and Conditions | 3.4 Fl 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.at/products/353780539-diamax-advanced-3-38-oz](https://www.desertcart.at/products/353780539-diamax-advanced-3-38-oz) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-07-25*
