NIOXIN Density Defend Diamax Advanced Hair Thickening Serum

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!

I absolutely love this product! I have an area around my bangs where you can see straight through to the scalp. My hairdresser recommended it to me, saying with even the first use, the hair would appear much thicker, leaving less scalp visible. Well, let me tell you, there was NO scalp visible. It obviously didn’t miracle grow my hair that day, but it seriously boosts the existing hair, making it look MUCH thicker and fuller. She also said it is great for energizing the area, which helps with hair regrowth. I’ll follow up with a later review about that part. If you need something to fill in some thin or balding spots, while waiting on other hair growth formulas to kick in, this is a great product for you!

Does help with making hair look fuller and thicker. But does dry my hair out. I’ve stopped using it because I don’t think the chemicals are doing my hair any good.

I’ve had these two itchy spots for almost 2 years and thinning. Dermatologist prescribed a 200$ cream that doesn’t work. This stopped the itching the in first use. It’s not greasy, very light and doesn’t burn. Great quality though I wish it was a little cheaper. Either way, it works and I’m happy! I’ll come back to update if the hair thickens

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 — 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.

Is this a hair treatment or a styling product? The product description makes it ambiguous. As a styling spray it does thicken my hair. As a treatment, I haven’t seen any difference. This is expensive for a hair styling product. You can find a similar product from a salon brand for less than this. And it’s non-returnable.

I started using Nioxin Diamax Hair Thickening Treatment, and I couldn't be more impressed! As someone with fine hair that tends to fall flat, I've tried numerous products, but this one truly stands out. First, the application process is straightforward. The lightweight formula absorbs quickly, and I love that I can apply it to towel-dried hair without any heavy residue. After just one use, I noticed an immediate difference in volume and thickness. My hair looked fuller and felt healthier, which is a huge confidence booster! I've been using it consistently for a few weeks now, and the results have only gotten better. My hair not only looks thicker but also feels stronger. Plus, I love that it doesn't weigh my hair down or make it greasy. If you're struggling with fine or thinning hair, I highly recommend giving Nioxin Diamax a try. It's become a staple in my hair care routine, and I can't imagine going without it now!

I have been using this product for about 2 years. It works so well on my thin hair. I can visibly see a "hair plump" when using vs not using. I continue to buy an use this as I have very thin hair. I have tried other products that promise to provide a thickening agent. I have yet to come across something similar. You will not be disappointed!

I really like this serum that makes my hair look and feel thicker. The instruction says to use it on wet hair. I don’t. I use it on my freshly shampooed hair. I work the serum into my hair using my scrubby brush. I comb my hair and use my hot air brush to style my thick feeling hair.

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!!!

Hair looks a bit fuller. Also, it smells like flowers or something. I had someone ask me why I was using women's shampoo

I bought it for my postpartum hair loss. 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.

I used it for the first time today and stuff I bought for a 1/4 of the price from the drug store did a better job. This stuff did nothing and for the price they should offer a return. I feel like I got taken. I’ll try it over the next few days and if it starts to do a better job I will update here honestly. Update…I am angry about this product. If we don’t feel disappointed enough having really thin hair we have to get duped by this company. $60 down the drain!!! And Amazon should not allow them to not offer a return or exchange.
