Solid shampoo, should we go for it?

TRUE: Because it is highly concentrated in active ingredients, 1 80 g bar of solid shampoo is the equivalent of two 200 ml bottles! While a liquid shampoo contains between 10% and 15% surfactants, a solid shampoo contains between 40% and 60%! A good deal then, especially as there is no risk of wasting it by squeezing the bottle to hard.

TRUE: By the time it reaches you, its manufacture has already drastically reduced water consumption: barely 5% to 10% of the final formula, compared to up to 80% for a liquid shampoo! What's more, once it's in your hands, there's no need to repeat wash: a single shampoo is enough, so less water is used in the shower... unless you like to sing.

FALSE: Like a liquid shampoo, a foam appears as soon as you rub it gently with water! Rich in surfactants, solid shampoo lathers and is just as pleasant and effective as liquid shampoo. Stop looking at him like that: you'll hurt his feelings!

FALSE: Is there a transition period for oily/dry/dull (insert any other stereotypes here) hair? Not at all! Switching to solid shampoo is gentle and painless. The formulations are almost identical to a classic shampoo; we just removed the water. But there's nothing to stop you taking it in turns, or even slipping it into your bag for those occasions when carrying a bottle around isn't really practical!
