I have noticed less hair loss
[This review was collected as part of a promotion.] The only thing I was unhappy with was the instructions doesn't state whether it's to be used on wet or dry hair. I have these kinds of serums for hair thickening and they are to be used on dry hair, unfortunately this stated neither wet or dry, thank god for Google. However I have noticed less hair loss whilst showering since using this along with the full 3 step system. The packaging is simple but you don't need fancy packaging. Not sure I would pay the price for the system myself. I feel I need longer to actually determine whether or not that it actually works. Time given isn't enough time especially with longer hair.

Smells lovely
[This review was collected as part of a promotion.] I loose quite a lot of hair so when offered the chance to try this I thought it may help. Smells lovely and lathers well. It has made my hair feel slightly fuller however it does dry my hair out which considering the price unfortunately means it’s not for me.

Effective hair growth serum
[This review was collected as part of a promotion.] Very nice scent - a nice minty smell. The nozzle helps minimise waste. There is a slight tingling sensation on the scalp but nothing terribly painful. It is a leave in serum as well so it doesn’t need to be washed off. It contains caffeine which stimulates hair growth. After using it for a while, I can see some baby hair growth. Will keep using it and hopefully it makes my hair fuller.

Great serum which you can tell it’s doing its magi
[This review was collected as part of a promotion.] Thank you so much to Influenster and Nioxin for this free complimentary product for a test and review to see how well will it work together with my hair.
The Scalp & Hair Treatment comes in a smaller 100ml spray bottle, which makes it very easy to apply directly to the scalp.
The packaging is lightweight and practical, and the pump delivers the right amount without waste. Like the shampoo, this treatment gives an instant cooling and tingling effect thanks to peppermint oil and menthol, and it leaves my scalp feeling refreshed right away. The formula also contains niacinamide and caffeine, which are ingredients often used to support scalp circulation and hair strength.
I’ve noticed that since using it regularly, my scalp feels less dry and tight, and my hair looks a little thicker at the roots. I especially like that it doesn’t leave any greasy or sticky residue and once it’s absorbed after a while you don’t even notice it’s there anymore. Out of the three products, this is the one I look forward to using the most, and it’s the one I’d definitely buy again even on its own. It feels like the key product that ties the system together and makes the biggest difference for me.
Highly recommended!

Not greasy at all!
[This review was collected as part of a promotion.] Lovely product does not make hair greasy 👌👌 I was worried about it making my hair look weighed down but I did not notice it doing that. However I am not a huge fan of the smell

Makes hair feel thicker
[This review was collected as part of a promotion.] I really like this serum. I feel like it makes my hair feel nice and I have definitely noticed it feeling thicker. I use it before blow drying and it makes my hair sit really well. I haven’t been using it super long but definitely will continue to use.
