It's formulated with innovative ingredients including SANDALORE™, caffeine, lauric acid, and niacinamide. Together they work to stimulate and nourish the hair follicles to prolong the growth cycle and improve hair resistance for fuller-looking hair. This effective leave-on scalp treatment is the first time SANDALORE™ has been leveraged to stimulate hair follicles and improve hair anchorage. *Via improved hair anchorage; average results in 8 weeks, in a double-blind clinical study with 120 panelists. Review: Good product - Good product. Review: It works amazingly - I bought this serum in May and have been using it consistently twice a week since then — and it’s been fantastic! My hair was shedding a lot due to stress, but now it feels fuller, healthier, and more beautiful. I’m genuinely so happy with this purchase and will definitely be buying more. Yes, the scent is very strong — and I’m someone who usually avoids strong smells, especially before bed. But I found that applying it early in the morning works perfectly; by nighttime, the scent has faded completely. This isn’t a hair growth serum but a density booster — and it absolutely delivers on that promise. ## Features - Reduced hair fall - 93% of users noticed less hair in their brush. - Better hair resistance - 91% of users noticed improved hair anchorage. - Thicker, fuller hair - 93% of users felt they had stronger hair when using our leave-on treatment. - Healthier hair and improved hair density - 90% of users noticed a reduction in hair breakage. - Free of parabens, sulfates, and colorants. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C1QDP2R7 | | Active Ingredients | Niacinamide, Caffeine, Lauric Acid, and Sandalore | | Age Range Description | Adult | | Age range (description) | Adult | | Best Sellers Rank | #11,985 in Beauty ( See Top 100 in Beauty ) #142 in Hair Regrowth Treatments | | Brand | NIOXIN | | Brand Name | NIOXIN | | Customer Reviews | 4.0 out of 5 stars 691 Reviews | | Hair Type | Thinning | | Item Form | Drop | | Item Volume | 70 Milliliters | | Item form | Drop | | Manufacturer | Nioxin | | Manufacturer Part Number | 99350182438 | | Material Type Free | latex_free | | Material type free | latex_free | | Model Number | 99350182438 | | Number of Items | 1 | | Recommended Uses For Product | *Use daily for visibly thicker, stronger hair. | | Scent | Sandalwood | | Scent Name | Sandalwood | | Unit Count | 70 Milliliters | ## Product Details - **Active Ingredients:** Niacinamide, Caffeine, Lauric Acid, and Sandalore - **Brand:** NIOXIN - **Item form:** Drop - **Item weight:** 2.3 Ounces - **Scent:** Sandalwood ## Images ![Hair Fall Defense Kit Duo Sets | Leave-In Hair Treatment | Shampoo | The Power of Two: Shampoo for Hair Fall & Intensive Daily Leave-In Hair Treatment for Thinning Hair - Image 1](https://m.media-amazon.com/images/I/610TT0prduL.jpg) ## Questions & Answers **Q: is this a foam and can it be decanted into travel size bottles?** A: This is not a foam.

The research around benefits of sandalore is very preliminary and apart from making your scalp smell like incense it's likely not doing anything. If this was a more appropriately priced I would rate it higher (maybe) ## Frequently Bought Together - Nioxin Hair Fall Defense Intensive Daily Leave-In Hair Treatment | With Niacinamide, Caffeine, Lauric Acid, and Sandalore | For Thicker, Stronger Hair | 2.3 Fl Oz. - Nioxin Scalp + Hair Thickening System Kits | For Natural, Colored, & Damaged Hair with Light to Progressed Thinning | Strengthen & Boost Hair Density with Niacinamide & Biotin | 1 Month Supply - Nioxin Scalp + Hair Thickening System Kits | For Natural, Colored, & Damaged Hair with Light to Progressed Thinning | Strengthen & Boost Hair Density with Niacinamide & Biotin | 3 Month Supply --- ## 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/717546261-hair-fall-defense-kit-duo-sets-leave-in-hair-treatment](https://www.desertcart.us/products/717546261-hair-fall-defense-kit-duo-sets-leave-in-hair-treatment) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-21*
