Cleanses the hair really well. I’ve not seen much growth but fallout has been reduced.

I’ve bought it because of my postpartum hair loss. It is too early for me to rate how well it will work as I’ve only used it for a few days (although it did work great after having my first child!) but what I’ve noticed in comparison to the old version is that the conditioner is amazing and I’m thinking about continuing to use this shampoo even after my hair stops falling out (fingers crossed!) as my hair just looks so much more healthy and shiny!

Have purchased this before (hairdresser advised me to after my hair began breaking off at nape of neck). Amazing - if used properly it lasts ages. It really works - would recommend!!!!

First thoughts are - I found this shampoo duo left a residue build up ,which left my hair feeling heavy and dull . It’s probably due to the nature of the product. Will use till the end and evaluate the results then .

This product was advised by my hairdresser for thinning hair , I have extreamly thin hair, it does take a while for the volume to build up, the conditioner is lovely , you don’t need to use a lot.
Same goes for the shampoo , (hope this helps ) I know there are lots of different thickening shampoos out there, this is my choice, kind,regards Sandra,

Amazing stuff. Great value for money. Leaves hair and scalp feeling extremely clean and soothed. The conditioner also leaves it beautifully soft.

Was supposed to be a twin pack of the new product but received new shampoo with old conditioner. Was bought as a gift so not ideal!
Good product though & delivery quick & efficient.
