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 ...

Another hair treatment
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...

Fantastic Product!
Hair Type Straight Hair
This product does exactly what it says it will do! My hair is so thin you can see my scalp. I have been using this for a week now and the difference is amazing! My hair looks thicker and I can actually style it! I will definitely be buying this again!
Works But Slowly
This product works but does so slowly over time. You have to use this consistently and almost everyday to see any type of results. It is expensive but if you can find it on sale or with coupons it is definitely worth it.
Changed the formula and it's a no!
Hair Type Straight Hair
I've used this product for years, I mean years! And they charge the formula and now my hair is super flat, no volume at all like it used to. This was absolute trash and I'm mad at the company now. Like they don't think we'll notice the changes. Do not buy it!!!!
Worked for me
Hair Type Wavy Hair
I'm post menopausal and noticed my hairline receding years ago. I didn't want to use minoxidil since the growth goes away when you stop using that. I used this sporadically (almost but not every day) along with oral biotin. This truly worked to my surprise. I like that the ingredients are natural. No smell or oiliness. Very happy. I would recommend and buy again,
Gives flat hair a nice lift!

As someone with fine hair it sometimes falls a little flat. The formula felt really lightweight which i liked because although i want volume i don't want my hair to feel super heavy. The product was also really easy to apply.
