So this is the shampoo + conditioner I've been trying for a couple of weeks. The smell of the shampoo is just divine... Not overpowering or perfumy, just a waft of the ultimate luxury scent of pure jasmine essential oil. Like having a shower in The Garden of Eden! :) The leave-in conditioner is tricky to get right, too much and it gives you sticky/crunchy hair. But it too smells lovely, almost a bit like bubblegum. I will probably get the Tommyguns Fig, Plum & Marshmallow conditioner and use the leave-in conditioner for extra treatment in winter.
These are sold in John Lewis stores as far as I know, but they can also be bought online. They are decently priced at £4.99 each.
Once you smell the Jasmine and Nettle Shampoo you will be hooked forever, as with MOP Pear Body Wash! :)
