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: Great value - If you already love this product, buying it this way is a great value. Having it delivered right to your door is incredibly convenient. I’ve noticed that it seems to support healthier hair overall β€” helping with breakage and making my hair feel stronger. It also appears to promote better growth by supporting the hair at the root. Overall, a convenient and cost-effective way to keep this staple on hand. ## Features - Fuller, Thicker-Looking Hair: Nioxin Intensive Diamax Advanced is a hair thickening treatment that enhances the appearance of fuller, thicker hair. - Boosts Hair Diameter: This advanced formula boosts the diameter of each individual hair strand, creating a voluminous and thicker look. - Strengthens and Protects: The treatment strengthens and protects the hair, reducing breakage and promoting healthier, more resilient strands. - Nourishes and Energizes the Scalp: Diamax Advanced nourishes the scalp, providing essential nutrients and energizing the hair follicles for improved hair growth. - Suitable for All Hair Types: Diamax Advanced is suitable for all hair types and can be used daily as part of your hair care routine. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B086G3LFD1 | | Best Sellers Rank | #11,673 in Beauty & Personal Care ( See Top 100 in Beauty & Personal Care ) #182 in Hair Regrowth Treatments | | Brand | NIOXIN | | Brand Name | NIOXIN | | Customer Reviews | 4.4 out of 5 stars 1,061 Reviews | | Hair Type | All | | Item Form | Serum | | Item Volume | 0.34 Fluid Ounces | | 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 | | Scent | Unscented | | Scent Name | Unscented | | Unit Count | 3.38 Ounce | ## Product Details - **Brand:** NIOXIN - **Item Form:** Serum - **Item Weight:** 3.4 Ounces - **Recommended Uses For Product:** Professional Salon & Spa - **Scent:** Unscented ## Images ![Nioxin Hair Night Density Rescue Serum + Density Defend Diamax Advanced - Image 1](https://m.media-amazon.com/images/I/61aRjYwq5iL.jpg) ## Available Options This product comes in different **Style** options. ## 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.
