The best shampoo and conditioner ever!!
I have used Nioxin for years. I wanted to give the age defense shampoo and conditioner a try. I have really, really bad hair. These products support my scalp and makes it so much better. If you have not great hair like I do please try the shampoo and conditioner together. I think you will love it. I have tried just about everything there is to try for fine aging hair and this one is it. Thank you Nioxin. I am a customer for life. 🩷🩵🩷🩵

Winner
[This review was collected as part of a promotion.] This shampoo was very easy to lather and rinse. So much so that I was able to do a double shampoo, easily, which is the method I prefer for my scalp. It did not leave any residue and left the appearance of my hair, seeming strong and shiny.

Love!
[This review was collected as part of a promotion.] Absolutely love this shampoo. It doesn’t super lather to start, but as you mix water with it a nice lather develops. It leaves my hair feeling super clean and rinses easily.

Fresh
[This review was collected as part of a promotion.] The shampoo bottle has a simple yet original design. The liquid is clear and doesn’t lather much upon application, which may appeal to those who prefer a lighter formula with fewer bubbles. It leaves hair feeling fresh after washing.

Scent
Not sure if I’d like it or not the scent is extremely overpowering and caused migraines, donated it.

Nice mild shampoo
[This review was collected as part of a promotion.] The Nioxin Age Defense Shampoo is a very nice mild shampoo. It doesn’t dry out my hair and it leaves it soft and clean feeling. I like the scent, it isn’t an overwhelming perfume but rather a light minty scent. I received this product free in exchange for my honest review.

Love it!
I bought this a month ago. And although I do not shower my hair more than 1 tops 2 times a week it's already feeling and looking thicker. Best shampoo I've ever tried since I started to have thinner hair due to hormonal issues. Worth trying *thumbs up*

A lot of hair falling
I noticed a lot of my hair falling since I started using this shampoo and conditioner I’m glad I bought the 5 oz and not the big one, I’m disappointed because a couple of months or a year ago I bought the blue one (maybe#1) and I noticed my hair improved but not this time I thought it was only at the first couple of uses but I’m almost done with the bottle and my hair keeps falling a lot more than before I started using it.

Good for cleaning!
[This review was collected as part of a promotion.] I love how cleaning and clarifying this product is. My scalp feels super clean and fresh after using it. The bottle has a very easy to use design and it goes on and lathers well. The smell however is not the most pleasant.

Okay
[This review was collected as part of a promotion.] This smells nice but doesn’t sud up very much. I feel like I have to use a lot. I try to let it sit for a bit for the effects but I’m not quite sure if it’s helped. My hair does look healthy and has been growing but idk if that is from the shampoo.

Great product smells amazing and actually works
[This review was collected as part of a promotion.] The new Nioxin Age Defense line is by far my favorite products from Nioxin so far. This shampoos smells fresh in floral that gives us such an amazing scent. My hair smells good all day long and it’s easy to manage. The shampoo lathers up really well which I really like. It makes me feel like my hair and scalp are being clean properly getting all the toxins out of my hair and my shit off my scalp. I haven’t had any dryness or redness from using the shampoo at all. I have had great results with hair growth. I’ve been using the shampoo about two months and I have at least an inch of new hair growth. I even have baby hairs now that I haven’t had in years. This product works so well I definitely recommend it and will be using it long-term.

Hair growth shampoo
[This review was collected as part of a promotion.] To sum it up: it is okay. It didn’t make my hair feel more nourished or smooth. I don’t think I noticed all that much difference in my hair growth tbh. Maybe more baby hairs ?

Nice
[This review was collected as part of a promotion.] I like that this came in a set. The smell was good. Not my favorite but nice. Made my hair nice shiny and smooth. It was effective for what it says it does for your hair.

Great product.
[This review was collected as part of a promotion.] It gives my scalp this super clean feeling which I love. I feel refreshed without it being weighed down. My hair definitely looks shinier. If you have dry hair it can make that worse so make sure you pair it with a good shampoo.

No strong scent
[This review was collected as part of a promotion.] The scent is very herbal and mild, I do like that. I dont know if it is making my hair more fuller, but even since I started using the serum along with this, my har loss has become significantly less.

Cleansing shampoo
[This review was collected as part of a promotion.] This shampoo helped clean my roots without flaking it too much. I like the consistency and scent of the shampoo. It lathers well and rinses easily.

Aging like fine wine
[This review was collected as part of a promotion.] I really like this product. For someone who is closer to 40 years old this shampoo makes your hair feel like you’re in your 20 years old. The shine and strength I have after each use is fantastic. Lather rinse and repeat

Lathers well
[This review was collected as part of a promotion.] This shampoo lathers well and isn’t too runny. It smells good and left my hair feeling clean,but I do feel like it leaves some residue on my scalp.
