LUSH solid shampoos

the product
LUSH's shampoo bars are hockey-puck shaped. they're quite dense, and not crumbly. they also lather up beautifully!
the best thing about solid shampoos is how long they last. while you can use a bottle in about a month (two, tops), one puck can last double that time. it's also less packaging: all you need is a tin to keep it dry between washes.
the only drawback is that you cannot have it near water while not using it. otherwise, it'll become a sticky, fizzy mess!
how to use?
after getting your hair wet, in the shower, you rub it on your hands (like you would a soap bar). then, you rub the puck on your hair. three-four strokes (top, bottom, and sides) are more than enough. lather, then rinse.
it's that easy!

and now, here are my experiences with four solid shampoos ...
