A mousse by any other name
This product is overpriced. In Australia for the same price you receive a set consisting of 150ml shampoo and 150ml conditioner plus 40ml of the hair thickener which is actually a mousse. The advertising on the Amazon site actually shows these 3 products in one image on the LHS of the main image. This image should not be there as it is misleading. So what do I now have? An overpriced mousse which you can pick up anywhere at a fraction of the cost.

GENIAL
Llevo usando los productos de Nioxin 2 años y mi pelo es otro completamente. La única pega es que la espuma final puede escocer unos segundos, pero merece la pena.
