John Masters's products have always played well with our 'natural' and 'green' Beauty Bible testers: he's a truly 'eco' hairdresser from New York, passionate about the nature-powered haircare which he uses in his salon - which is happily available on this side of the pond This is perfect for this time of year: decant some into a smaller bottle and take to the beach, where it works as a brilliant leave-in conditioner and helps to stop hair getting all tangled from salt water and sea breezes. It nourishes with a combination of 18 certified organic ingredients, including shine-boosting wheat and soya proteins, borage oil, and smells just cheery: a blend of grapefruit, lemon and neroli.

Another of our favourites from John's range (he's the nicest man you could ever wish to know, BTW) is the John Masters Lavender & Rosemary Shampoo - good for all hairtypes, though targeted at 'normal hair' (er, do you know anyone who has that...?) Gorgeous wake-you-up scent, gentle lathering, and leaves hair silky.

If you do ever get the chance to visit his Organic Salon & Flagship Store on Sullivan Street in New York, treat yourself to the Shiatzu Scalp & Hair Treatment - literally one of the nicest things ever to happen to our follicles.

And meanwhile? Enjoy John's 'takeaways'.
