Love love love!

[This review was collected as part of a promotion.] This product may be small but it packs a punch. Lovely refreshing again almost minty scent I use this mousey product up at the roots of my hair massaging into the thinning and balding parts. I then blow dry and style my hair as normal using some heat protection through the ends of my hair. This product may seem on the more pricey side however you get what you pay for and in 30 days i see and feel the difference again clear concise packaging.

Fabulous Nioxin Treatment

[This review was collected as part of a promotion.] This hair treatment has been a brilliant product to add to my hair regime. I have been using it alongside the shampoo and conditioner from the Nioxin line. I've really enjoying seeing the improvements this regime has made to my damaged hair, the treatment feels like a lightweight serum, but really leaves my hair feeling moisturised and nourished

Strong minty smell but it works

[This review was collected as part of a promotion.] Wow. I was suprised that this stuff actually works… I was given this Nioxin hair loss serum along with the shampoo and conditioner set. This has quite a powerful minty smell to it but it does do exactly what it claims to. My hair was thinning due to prescription medication I take and since using this my hair feels a lot thicker and has more power to it. I highly recommend this
