In love!!
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!

This WORKS!
Iâm 67, and have fine, quite thin hair that has thinned some over the last few years. Today is my third day of use, and WOW, what a difference! Iâm using a volumizing mousse with it, and canât believe how much thicker my hair looks. It also has stopped breaking. Iâm totally sold, and have subscribed. Yes, itâs expensive, but itâs the best thing Iâve ever used on my hair/scalp for volume.

This stuff works!
I have noticed a huge difference in the thickness of my hair. I cannot live without this now! It is a little on the pricey side for me but it works too well to stop using it!

NOT WORKING
I am using it regularly for 1and 1/ month and experienced much worse result than at the beginning. I use a comb with the 1/4 inch between the Thees and still there are hair I am still left.I am sorry it is too late to return but HOW YOU CAN KNOW if it is helping or not in the time less than a month

I feel like my hair looks thicker since I have been using this for a couple of weeks now. Peppermint also makes my scalp feel refreshed

Helping my thin hair
Easily applied after partially drying my hair. Thickens my hair so it looks fuller and brightens my hair with a nice shine.

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 â ï¸ 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 have oily hair and the best thing about this serum is that it does not make hair oily and can be used everyday; it has a good influence on hair; now I am repeating it.

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.
