Review: This serum is liquid gold in a bottle! - I've noticed that my hair has been falling out in clumps in the shower pretty consistently for a while now. My hair used to be pretty thick, but I've noticed recently that my pony tail was looking a lot thinner than it used to, which was a little upsetting. 🫠 I've tried a few different hair loss/hair fall shampoos and serums over the year and I finally found one that works for me! I used this for a week and I feel like I noticed that the hair fall I had in the shower had reduced significantly! At first, I thought that maybe it was a coincidence, but even since I've started using this consistently every night, I haven't had another instance of increased hair fall in the shower. I've been using this every night (2-3 droppers full) all over my scalp. It works well on dry or damp hair, as it has alcohol in it, making it dry pretty dang quickly. It smells really nice, does not leave any sticky residue, and leaves a nice minty feeling on your scalp after you work it in there. I think my only problem with this is that, the instructions says to use 2-4 droppers each time. However, I find that if I keep doing that, I'll go through the bottle way too quickly and this stuff is NOT cheap. I may have to try using a little less each time, and hopefully it still works. Obviously, my personal experience is anecdotal, and depending on what the cause of your hair loss is, this product may not work for everyone. But for me, this stuff is like liquid gold in a bottle! This review isn't sponsored or anything (though, I'd definitely love it if it were πŸ‘€), just wanted to share my personal experience. Review: yes - I'm not totally sure what type or specific category of voodoo magic this is, but I've been converted. consistency of water, and dries just as fast, if not quicker than water. does not leave a hint of grease or residue on hair, scalp, or pillow. scent is light but pleasant. bottle is bigger than i expected. directions say to apply 3-4 drops nightly, but i do about 7-10 tbh. it literally dries so quick and i cant feel it, so it sometimes leaves me like "did it even go on?" but it must, because i got actual real life results. within like 3 days my hair looked healthier. within a week i had about half the amount of hair falling out in the shower and during the day. after 2 weeks, one of my widening parts definitely looked fuller. the other widening part i haven't noticed a change though. after 3 weeks, my hair looks thicker and more full, with volume. you must be consistent with this and use it every single night. maybe twice i skipped 2 days in a row and the hair falling in the shower increased like immediately. once i started back up, it decreased again. so idk if that means i just need to use it for the rest of my life...? I'm 1 year post partum, but my hair falling, thinning, and widening parts is like 90% due to age, stress, and scalp flakes/dandruff/seb. dermatitis. 36 year old female. ## Features - Overnight leave-on treatment, clinically proven to increase hair density associated with scalp surface oxidation - High potential to neutralize free radicals, avoiding possible damages on the scalp ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B087KG95BK | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #10,221 in Beauty & Personal Care ( See Top 100 in Beauty & Personal Care ) #58 in Scalp Treatments | | Brand | NIOXIN | | Brand Name | NIOXIN | | Customer Reviews | 4.3 out of 5 stars 1,286 Reviews | | Hair Type | Thinning | | Item Form | Serum | | Item Volume | 62.4 Fluid Ounces | | Item Weight | 2.4 Ounces | | Manufacturer | Nioxin | | Manufacturer Part Number | 070018102942 | | Model Number | 070018102942 | | Number of Items | 1 | | Recommended Uses For Product | Professional Salon & Spa | | Scent | Unscented | | Scent Name | Unscented | | Unit Count | 2.4 Ounce | ## Product Details - **Age Range (Description):** Adult - **Brand:** NIOXIN - **Item Form:** Serum - **Item Weight:** 2.4 Ounces - **Scent:** Unscented ## Images ![Nioxin Hair Thickening Serum | Night Density Rescue Serum | Density Defend Diamax Advanced | For Thicker, Fuller-Looking Hair | Against Breakage - Image 1](https://m.media-amazon.com/images/I/61iZ2g+M9wL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Good for 85 year old woman?** A: I would be happy to assist you with this question today.

Have a Beautiful Day! **Q: What exactly is scalp surface oxidation?** A: To answer your question about Nioxin Night Density Rescue concerning the scalp surface oxidation and what it is exactly the following will explain more. Recent studies have shown that free radicals in the environment can trigger scalp oxidation and ultimately, hair thinning, Free radicals are unstable molecules that in an attempt to become more stable, steal electrons from other molecules which results in oxidative damage. This process is similar to the skin damage caused by the sun. To combat and minimize this damage in the world of skin care, there are a multitude of night time product regimens that both protect and repair skin. As night is the optimum time for the body to rest and repair itself, this is a prime opportunity to treat the hair and scalp as well. This is why we recommend our Nioxin Night Density Rescue to assist with repairing the scalp from damaged oxidative issues. I hope this was helpful to you.

My hair is long and waist length, normal shed is about 100 hairs a day, but this had increased. I increased protein intake which did help. I have always taken MSM (Methylsulfonylmethane) supplements which have given me very thick hair, and have continued them ( 2000 mg daily) I have been taking Minoxidil generic 5%, for about 5 years already ( to combat post menopause hair thinning) which continued to help. But due to a drug reaction, (not the glp, another rx) I became severely sick, could not eat or drink much for two weeks, ended up the the hospital for a week, had a platelet transfusion. I was very sick. I am ok now, but after leaving the hospital I began losing baseball sized wads of shed hair daily. My hair had dramatically thinned. From a medium ponytail to a pencil sized tail. Probably have lost 3/4 of my hair thickness. Then I started this product, within 3 weeks less hair was dropping, and after about 4 -6 weeks, hair thinning is down to less then 50 strands a day. Dramatic difference when I brush hair. I still need to regrow lost hair, which usually takes about 6 weeks to get going, and it i will be awhile for it ta catch up enough to be noticed in my length and fullness. But less shed is amazing. I apply daily, many drops all over entire scalp (not just three like listing says) - Fully recommend this! Update added. Its been 4-5 months since orginal review. Still using, and recommending this product. I now loose maybe 10 to 12 hairs aday in normal shedding. My hair is super super thick, and length is growing as well. Still taking Ozempic, but you would never know from my hair thickness. At age 61, it's the fullest it has ever been. Much fuller then in my youth. Still using minoxidil, and MSM supplements. Highly recommend this product. ## Frequently Bought Together - Nioxin Night Density Rescue Serum | Overnight Hair Thickening Serum | Protects Against Hair Breakage | Intensive Treatment with Oxydine | 2.4 Fl oz. - Nioxin Density Defend Styling Root Lifting Spray | Hair Thickening Spray | Texturizes and Volumizes | 5.1 Fl oz. - Nioxin Density Defend Hair Thickening Gel | For Volumizing and Fuller Hair| No Stickiness or Stiffness | 5.1 Fl Oz --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/202250885-nioxin-hair-thickening-serum-night-density-rescue-serum-density-defend](https://www.desertcart.us/products/202250885-nioxin-hair-thickening-serum-night-density-rescue-serum-density-defend) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-09*
