Nioxin Density Defend Diamax Advanced Hair Thickening Serum With Caffeine, Niacinamide & Panthenol For Thicker, Fuller-Looking Hair 3.38 Fl oz

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 have thinning hair on top due to aging. This Nioxin just adds strength and depth to my hair. I love it! I have been using for many years.

I love this product. Makes my hair feel thick, smooth and shiny.

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

This stuff actually works like magic. It made my hair look 3 or 4 times thicker and I loved it!!! However, it takes a lot for me and it is pretty expensive for 3.3 oz. I will still use it though, but not use so much. I will probably save it for special occasions.

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 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!

Great product

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!!!

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.

Price is too much. But it helps. It is not comparable to head and shoulders tonic but unfortunately it is discounted.

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.

Parfait pour mes cheveux post-partum! J’ai vu une amélioration de la pousse de mes cheveux en peu de temps ! Je recommande!
