Okay
[This review was collected as part of a promotion.] The texture is nice but it has such a strong chemical smell - this is expected as it’s a “treatment” conditioner. The label says that it can only be left in the hair for 2/3 minutes; this is definitely true as any longer and your scalp will start to feel icy cold! I can’t make a comment on the effectiveness of the conditioner as I have only used it once - however with the 1l size bottle I am sure there are plenty uses!

Good feel but smell is not for me
[This review was collected as part of a promotion.] I got this for free from influenster and Nioxin in exchange for my honest opinion. Lightweight texture but feels super nourishing. Made my scalp tingle but in a way that felt satisfying, good value in the larger size which was still fairly easy to use. The scent for me is overpowering and minty and it lasts a while so not my favourite.

Avoid if you like to feel like you can breathe in
[This review was collected as part of a promotion.] I'm not going to lie, after barely surviving the shampoo process, feeling gassed and burned by menthol, I couldn't face opening the conditioner and putting it anywhere near my head! It might be a good product, but only those with no sense of smell will ever find out!

Refreshing Conditioner with a Cooling Boost
[This review was collected as part of a promotion.] Generous-sized bottle with the same fresh menthol scent and cooling tingle that feels great on the scalp. Leaves hair soft and refreshed, though it doesn’t detangle quite as well as some other conditioners I’ve used

Huge bottle
[This review was collected as part of a promotion.] I tried this for a month as part of a 3 step system, as my hair is thin and fine, but also I’m losing a great deal recently due to new medication. Unfortunately, the serum gave me a sore scalp and I only noticed a slow in the hair loss rather than a thickening improvement. As a conditioner, it leaves the hair smooth and not too heavy or claggy. The bottle is huge, and will last for considerable time! The product is not hydrating enough for bleached hair, for this reason, I would not repurchase.

Left my hair feeling soft and full of volume
[This review was collected as part of a promotion.] This conditioner makes my hair look great. I have the litre bottles which last ages (I would guess 3 months or more). After using 3 to 4 times a week for 6 weeks I still have at least half a bottle of each left so I will keep using until it runs out (posting the review now as it is due). The shampoo and conditioner bottles are very similar, but the conditioner has a white lid (I remember white lid for clean hair). The conditioner is white and a medium consistency which is easy to dispense and apply. You are meant to massage it into your hair and leave it for a few minutes. After using it my hair feels pretty detangled and smooth. I love how the shampoo and conditioner make my hair feel when used together, and it has more body which makes the length of the hair look thicker. I haven’t notice new hair growth.

Great minty scalp and hair treatment leaving hair
[This review was collected as part of a promotion.] I received this product in exchange for my honest review. I was testing this product for a month. My observation is that applying it after shampoo makes your hair softer and its minty scent give you cooling feeling on the scalp which is a plus. My hair looks thicker and fuller and definitely helps to get better volume. It is not leaving residue after rinsing it off and it is perfect consistency, white colour. It is great feeling on the scalp, feeling that it works. Will definitely recommend it if you want that your hair looks thicker and fuller. My hair was soft and shiny at the same time after using it together with shampoo from the same line. My baby hair start appearing more on the areas of concern on my scalp however it did not stop my hair falling.

Great
[This review was collected as part of a promotion.] Great soothing conditioner. Really fresh minty smell. Leaves my hair looking and feeling fuller with no weight or residue. The only down side is it's not very detangling

Good but not excellent
[This review was collected as part of a promotion.] My partner tried this shampoo, conditioner and treatment for the past 8 weeks on his natural hair. It started thinning out on his hairline and so we thought this would be excellent for thickening it up. Whilst we found that the thicker parts of his hair did seem healthier and somewhat grew quicker, the thinner areas around his hairline didn’t change very much. It’s a very good product in terms of how it treated his hair, but we wouldn’t rush to buy it in the hopes of it thickening the hair much. The smell is quite nice and fresh and you do get a lot of product for the value.

Silky soft
[This review was collected as part of a promotion.] This product comes in a convenient three-step system and is packaged in a 1-liter bottle. It is easy to use and delivers a refreshing, minty sensation while leaving the scalp thoroughly cleansed and revitalized. For best results, use at least three times per week. Regular use may help improve hair thickness. Formulated with niacinamide, it supports the scalp’s natural detoxification process. Left hair detangled and soft.

Lovely
[This review was collected as part of a promotion.] The scent is great. It feels minty and fresh on. Lathers really well. Huge bottle so lasts for ages well worth the money. It makes your scalp feel so fresh and its so pleasent to use. I noticed less hair shedding and hair felt clean and refreshed. Left my hair shiny and smooth and felt very conditioned

Great results in short time
[This review was collected as part of a promotion.] After using it for couple weeks I can already see and feel a difference. My hair feels stronger, looks fuller, and my scalp feels much healthier and more refreshed. It’s lightweight, doesn’t weigh down my fine hair, and has a minty, clean scent that feels invigorating. I love that it targets both scalp and hair health. Definitely worth it.

Great conditioner
[This review was collected as part of a promotion.] This is a great conditioner. It left my hair feeling really soft and didn't leave my scalp sensitive. I love the big 1L bottle it will last me a long time. And like the shampoo I'm not keen on the scent but not enough to stop using. It's a great product

Silky soft
[This review was collected as part of a promotion.] I have been using this product, along with the shampoo and hair treatment for a while now and I am pleased with the results. I have light thinning, damaged hair that gets oily super easily and usually remains fizzy and hard to tame. This conditioner has really helped in giving me that soft touch on my hair without weighing it down or leaving any residue. The packaging is huge and a pump would be practical to dispense the product. The fragrance is not my favourite, but is super refreshing in the summer.

Softens the hair and leaves it feeling soft and no
[This review was collected as part of a promotion.] I have been using this set of 3 for 3/4 weeks and 3 times a week I’ve been using it. I use the Shampoo first then follow with the conditioner. My hair feels so soft and fresh after using these together. The conditioner really softens the hair. I gave it 4* because it’s too soon to tell if it’s thicker. But I’m feeling like I’m not losing as much hair as usual. I love the smell of my hair after too.

Volume for fine hair conditioner
[This review was collected as part of a promotion.] Love this conditioner, it smells amazing, my hair was damaged due to bleaching it and this conditioner helped build my hair back up and added great volume to my very thin hair, it is very smooth and glossy, and surprisingly not too expensive for a massive bottle of conditioner xx

Hydrated
[This review was collected as part of a promotion.] I tried the kit and I love how my scalp looks after use it, it feel more hydrated but the thing I didn’t liked much it’s the scent it’s too strong which I find a little bit annoying because I feel It’s too much and it feels so cold

Already repurchase! Fab
[This review was collected as part of a promotion.] A perfect companion to the shampoo. The conditioner leaves my hair feeling soft, manageable, and noticeably thicker. It has the same minty, refreshing scent which adds to the salon-like experience at home. I’ve seen a real difference in regrowth and texture since starting the System 1 range. Highly recommend! Great value for money and well packaged

Ok
[This review was collected as part of a promotion.] I was given this a part of a 3 step routine. The scent was ok, it didn’t feel particularly luxury smelling but this isn’t a game changer if the product works well. Unfortunately I didn’t notice any difference in hair growth or less fall out but I do already have very thick hair so this could be why. The bottle size is great and the same as my usual bottle sizes as I tend to always purchase 1L bottlers, however I found it a bit unhelpful to not receive a pump with it (this is not the standard with most 1L bottles though just to add). It was a decent enough shampoo/conditioner/treatment to use for general use though, I still have a fair amount of the bottles left to get through and will continue to use it all.
