Lorenay The Incredibles 2-in-1 Bath & Shampoo 475ml

The Incredibles is the one to buy when you are not sure. It works across a wider age range than Minnie or Cars, it is not tied to a gender the way Pony tends to be, and in a house with more than one child it is the bottle least likely to start an argument.

Lorenay make it in Spain and it does both jobs from one bottle, bubble bath and shampoo. The formula is extra mild, pH-balanced so it does not disturb the natural hydration of skin and hair, and it carries vitamin E and vitamin A. No parabens.

Practically, one bottle in a shared bathroom is one bottle to keep track of instead of several half-used ones lined up along the edge of the tub.

The formula is the same across the whole Lorenay range. Minnie Mouse, Star Wars, Disney Cars, My Little Pony and The Incredibles are one product in five bottles. So do not agonise over which is better for their skin - buy the character that will get them into the bath without an argument. That is the only difference that matters here.

Ages 3 and up. This is not a baby product. For infants and newborns the Kodomo hair & body wash is the right choice, and it is formulated tear-free for exactly that reason.

Worth knowing: 475ml, which stretches a long way across two or three children at a capful a bath. It is lightly scented rather than fragrance-free, and it is not a tear-free formula, so keep it clear of eyes.
