Lightweight but nourishing
[This review was collected as part of a promotion.] I’ve been using the conditioner in conjunction with the shampoo and hair treatment from this Nixon line. I really appreciate the light weight conditioner, it leaves my hair feeling very nourished without feeling weighed down. The product smells great and is easy to spread through the hair.

Smells lovely!
[This review was collected as part of a promotion.] Nice conditioner, it’s got a lovely minty smell and has left my curly hair lovely and soft after I’ve used it.
It comes in a nice big bottle which I like as it makes it more cost effective.

Great system.
[This review was collected as part of a promotion.] I started using the Nioxin System 4 bundle for my coloured, thinning hair and noticed a difference within weeks. The shampoo cleans gently without stripping colour, the conditioner leaves my scalp refreshed, and the serum adds a healthy fullness. My hair feels stronger, looks thicker, and has a lovely shine. It’s a salon-quality solution that really delivers on its promise to improve scalp health and encourage thicker-looking hair. Great smell. Big bottles to last too.

Impressed!
[This review was collected as part of a promotion.] I am amazed by this product, I was very impressed by the size of the bottle, and after multiple uses, I am very pleased with how my hair looks and feels. It has a peppermint smell, which is very refreshing and the conditioner definitely leaves my hair smooth, silky and shiny and feeling healthier. Combined with the other two products from the range, my hair has had a complete overhaul!

Minty fresh conditioner and makes hair sooth.
[This review was collected as part of a promotion.] A minty fresh smell. Seems hair looks a bit thicker. Was amazed at the way this worked on my dandruff and kept my hair looking less greasy over a week. Unfortunately, it will run out of conditioner much quicker than the shampoo.

Game changer
[This review was collected as part of a promotion.] I’ve been using the Nioxin System 4 Hair Thickening Conditioner for a while now, and I’m seriously impressed. First off, a little goes a long way — even with my long, constantly bleached hair, I barely need any to coat everything. The minty scent is refreshing without being overpowering, and I love that it leaves my scalp feeling clean and invigorated.
I have blue hair, and one of my biggest concerns with any conditioner is colour stripping — this one doesn’t budge the colour at all. In fact, it makes my hair feel healthier and softer while also keeping it looking fresh for longer. I’ve noticed my hair gets less greasy between washes, which is a big bonus for me.
Because my hair has been through a lot of bleaching, breakage is always a problem, but this conditioner has really helped strengthen and protect it. After regular use, I can see and feel the difference in the texture and resilience.
It’s absolutely worth the money — I’ve been using it consistently and still haven’t even made it through a quarter of the bottle. Definitely a game-changer in my hair routine.

Conditions well without hair being flyaway.
[This review was collected as part of a promotion.] Good conditioner, not too heavy. Would have liked more scent. Overall this left hair feeling light and silky without feeling fine and flyaway.
