Why is the shampoo bottle clear, but not the conditioner?

I have no trouble getting shampoo out of the bottle, but I'm thinking of ripping apart my conditioner bottle...

Hmmm

Sitting by the kitchen sink
Waiting to cleanse thy hand
Best not to take a drink
For it may taste very bland


Washing the worlds worries away
Warming is its partner accompanying
All the bubbles drifting astray
Pleasuring the hands of even a king

Whirling down the drain
Healing small wounds
Easing the hand of pain
All will be better soon

The glory of Soap is true
For all people, me the king, and you.

I hate living in this spread out town where I have to drive ten miles just to get to a bus that will drive for twenty additional ones just to get to Walgreen's to buy ******* soap to wash my mother's back because she can't wash it herself.

Got soap in my eyes
Ow ow ow ow ow ow ow
It really hurts! Ow!
