Really Actually Works
I'm in my 50's and my hair is beginning to thin in certain areas. I've always had very thick, but fine, hair so I've never had to deal with thinning hair. This product actually made my hair feel thicker from the very beginning in the areas I was concerned about. It made my hair feel denser yet soft ...

My hairdresser recommended this product. Shortly after applying, it does soak in and dry up nicely. I do not like the smell, but I am also sensitive to perfumes in laundry detergents, so I buy the ones that are "fragrance free". I do not like the instructions at all. Every product Nioxin makes, says...

I love the way it smells, how it makes my hair feel after using it and ITS NOT STICKY! This formula is lightweight, and doesn't weigh down my fine hair. Most Nioxin products are a hard pass, because they are pricey & don't work. This one is a keeper. The spray nozzle makes it super easy & fast to apply!
Love it!

I have loved this serum! It is thickening my hair. It's very effective. The scent is pleasant. I'll definitely be buying this because it's a great value for what it does!
This stuff works - just wish it was unscented.

Love the texture - light and smooth. Not "sticky" or "greasy" feeling. Cute packaging, too. This stuff works! Only downside, for me, is the scent. Starts light, but lingers - unless you're sensitive to scents, like me, this shouldn't be an issue for you.
Healthier and thicker hair in no time!

I've been using this product for a few weeks now. I was a little skeptical at first because products tend to say that you can see results almost immediately. That isn't always the case, but I've genuinely noticed a difference in the thickness of my hair! I've always had thicker hair my whole life. After having covid, having a child, and losing 40 lbs in the last 3 years, I've been losing a TON of hair! I feel like this hair serum is getting me back on track for healthier and thicker hair. This serum is extremely easy to use! You just spray on your scalp in sections with the nozzle on the product. Once you've done that, you rub your fingers through your hair and into your scalp. Then you're done! You can style however you like. This hair thickening serum doesn't leave any greasy or stiff feeling on your hair at all! I only wash my hair twice a week, and I use it both times when my hair is damp. It says on the package that you can use this product every day! It does not have a strong smell at all. It almost feels like when you use tea tree on your hair, but it doesn't burn. Overall, after using it for a few weeks, I would definitely buy it again. It's not super cheap, but it's worth it if you are looking for a hair thickening serum!
My hair is still thin but need more time to see its effects

Can't definitively state whether this product worked because I need more time to use the product and observe its effects. My hair is still thin and flat after about a month of use. It does smell nice and is quite pricey though.

My hair is so thin and I am a diabetic, which is really bad for your hair anyway. My hair has broken off in CHUNKS! It looks horrible and is HUMILIATING! I don't even leave my house anymore!😢. I am using the generic form of Rogaine- for women, can I use this also? Or should I just use one or the other? Brittle and breakage...I mean SERIOUS BREAKAGE is my issue plus my hair is extremely fine/thin so it looks even worse and is more noticeable. It broke off behind/above ears, all around crown and some underneath!! Help! Any other ideas? Or advice? I'm all ears! No pun intended ugggh!
- Asked by Annie
- Official Answer By Nioxin - Brand EngageYou may use this product along with Rogaine. Yo may want to get your hair tripped to help even things out, give the style a shape, and removing split ends.Was this answer helpful to you
- Q
Does this work if I let my hair dry naturally? Also, is this thickening only temporary or does it actually help thicken each strand of hair after long term use?
- Asked by Mel
- Official Answer By Nioxin - Brand EngageIt works best as a styling aid when blown dry to reach full potential. It does penetrate each hair making it thicker stronger and protecting it against damage. A wonderful 2-in-1 product.Was this answer helpful to you
- Q
Can you tell me The differences between this advanced product and the regular one?

- Q
Is this a styling product or a treatment product?
- Asked by Frankie
- Official Answer By Nioxin - Brand EngageIt is both! It penetrates each hair strand making it thicker fuller and strengthened against breakage, while it gives added volume and definition to hair that is blown dry after application. This is truly a remarkable product.Was this answer helpful to you
- Q
I have the 3 piece kit, 3-D root booster, night density rescue & diamax advanced. I only wash my hair every other day. What products can I use day and night on days when I don't wash my hair & in what order should I apply them? Thanks!
- Asked by Sally
- Official Answer By Nioxin - Brand EngageThe Diamax Advanced should only be used before blow drying and styling your hair. The 3-D Root Booster should be used twice daily. And the night density rescue is to be used at night. In the morning I would recommend applying the Root Booster prior to the Diamax. On days that you shampoo in the morning use all of the system kit products prior to applying the Root Booster and Diamax. In the evening apply the Hair Booster followed by the Night density Rescue. If you are shampooing in the evening apply products in the following order: Shampoo, Conditioner, Root Booster, Scalp & Hair Treatment then the Night Density Rescue. Was this answer helpful to you
