Lightweight serum and reduces hair breakage and br
[This review was collected as part of a promotion.] Ive been using this nioxin anti aging hair serum and found a noticeable visible improvement in how my hair looks and feels. The serum is lightweight and dispenses easily without making my scalp greasy. Its absorbs quickly and leaves hair feeling smooth. I have experienced less brittleness and breakage which shows when used consistently this is making a difference. My scalp feels healthier after using.

🩵🖤 Great for hair
[This review was collected as part of a promotion.] I have been testing the Nioxin Age Defense Anti Ageing Hair serum and I instantly fell in love with it. After using applying it to me hair it left my hair feeling lucious and hydrated. The serum is easily manageable as the texture isn't too thick or sticky. It is packaged really well and the little dropper is easy to use.

Excellent
[This review was collected as part of a promotion.] I have been using that for over a month and I would say the results are viable after a month of use with shampoo and conditioner.
I coudnt believe if this is actually working but it is. My scalp doesn’t feel greasy and you can use this every day. Excellent hair serum

Nice lightweight serum
[This review was collected as part of a promotion.] This is nice but pretty low key serum. It’s really lightweight and doesn’t make my hair greasy at all, which is a big plus, and it sinks in quickly so it’s easy to use daily. I do feel like my hair looks a bit fuller and healthier, especially at the roots, but it’s quite subtle.

Soothing
[This review was collected as part of a promotion.] I have really high hopes for this lightweight serum, feels lovely on the scalp not oily or feeling greasy therefore no nasty residue, absorbing well into the scalp. Lovely scent very unique which I really do like. As it is early days I have yet to see the full results but I think with consistency this will strengthen the hair
