Rinse. Repeat.  

So, is there some reason, other than tradition/habit/expectations or a desire to sell more shampoo, that we are instructed to use a second dollop of shampoo?

I never repeat although I do shampoo daily. It may come from days when people would shampoo once a week whether they needed it or not.

I'm another person who only uses one round of shampoo. I suspect it's more marketing than anything else, but I suppose the shampoo folk would tellyou that the first collop cleans the heair and the second dollop allows the hair tor etain allthose wonderful things they put in to make your hair silky and bright and able to leap tall buildings at a single bound.

You know... that's a very good question.

I don't automatically double-shampoo by any means, but if I'm particularly sweaty or grimy I do.

But maybe it's just an EVIL MARKETING PLOY. Or maybe there's some compound in shampoo that will let the aliens track us better when the time for their invasion has come.

Possibly I need some caffeine.

I have always suspected marketing.

Shampoo can be harsh on the hair. It strips the oils out and roughens the cuticle. If they can get you to shampoo twice, not only do they sell more shampoo, they sell more conditioner.

I only do it if I've still got grime and/or styling products in my hair after the first wash. So about once or twice a year.

Another trick is to change shampoos once in a while. One brand will wash the residue that the other brand leaves.

I can't find my copy of Paula Begoun's excellent book Don't go shopping for hair products without me. She covers that question and more, divulging the secrets of recurring ingredients and what they do.

Another possible answer: oily scalp.

Um... meaning that there is a good reason for it?

Um, I think that's most likely an equivocal "maybe".

Activate random ass answering device:

I'm guessing that the first application gets the surface oils and dirt away, and that the second application achieves some sort of "deeper cleaning."

If it was a marketing plot, it has ceased to be an effective one.

Omigod. I had no idea I was the only person left on the planet that dutifully followed the instructions and shampooed twice. I have never, however, gotten stuck in the endless repeat-loop that results from following the instructions too literally. I may be a Virgo, but I'm not THAT bad.

No, there are actually two of us; I always shampoo twice as well -- albeit I use a fairly tiny dollop for the second lather. Generally, the first shampooing sort of works up a vague lather because of the scalp oils, and so it doesn't really feel like it's all gone when I rinse, and then the second shampooing works up a proper lather and rinses out properly taking the prior residue with it. Or, at least, that's what it feels like; I have no idea if it's true or not.

well, see, somewhere back down the line, they used to say "Lather, Rinse." Then someone with outstandingly dirty hair tried the directions, found their hair to yet be less than clean, and complained. Thus the companies now cover their otherwise liable asses by saying "Lather, Rinse. Repeat." They may make promises regarding getting your hair clean, but with directions like that, they need make no assertions about how much of their product is required to do so.

:P

(noting that the directions, if followed literally, send you into an infinite loop. I believe I have seen somewhere instructions that said something more like "Lather, Rinse. Repeat as desired.")

It's a holdover from when we washed our hair weekly instead of daily.

Some years ago, I noticed that that instruction had been removed from the shampoos I use. I thought it rather spoiled the joke about the programmer found dead in the shower with the empty shampoo bottle, myself.
