when i was younger i would make my own 'bath products' and 'shampoo' and 'conditioner' by taking all the different shampoos and pouring a bit of each into a bottle and mixing it up, i did the same for the 'bath products' and 'conditioner' then i would stick a label on each saying what they were, not that you could read it because i was about 5 and i hid the propper stuff
