John Frieda Sheer Blonde Go Blonder Lightening Shampoo and Conditioner

One of the flattering upsides of summer is that hair naturally lightens by a shade or two - which is something anyone who's mouse-to-blonde generally welcomes.

But we won't tell a soul if you cheat and 'enhance' the process with this new shampoo and conditioner from John Frieda.

We used to do this with a combination of lemon juice and chamomile tea - and as it happens, both ingredients feature in this duo - formulated in a more scientific way, for more reliable results, and with nourishing elements that soften and improve hair quality. (Nobody could ever accuse neat lemon juice of doing that, as we know from experience.)

Hair will be visibly lightened in as little as three washes, and the folks at John Frieda tell us that colour may be lifted by as much as two shades, after seven washes. If you're happy with your existing colour, try using this very occasionally, to 'brighten' it.

So for the rest of summer, we'll be having a blonde moment. In the best possible way.
