Hair.

A reader asks: I've been pondering hair. It’s so weird, hair is. Dead protein. That’s all it is. Do you know how much money is spent each year trying to get you to spend your paycheck on products to make your dead protein look better? Me either. But I bet it is a lot. How about a ballpark figure here?

First of all, ad spending on hair care products is expected top $1 billion this year, according to Advertising Age. That’s a lot of advertising.

U.S. Shampoo sales were up 0.7% to $620.3 million for the 52 weeks ending Sept. 10, according to Information Resources Inc., Chicago. Meanwhile, sales of conditioner were up 3.5% in supermarkets to $360.3 million for the same period.

My favorite quote from the research “Hair care was flat for a while” okay, I thought it was funny.

One more piece of info:

According to IRI, hairspray sales in the US were about $367 million last year and US gel and mousse sales were $581 million.

Add them all together? It's almost $2 billion a year. And this doesn't include hair color. That's $2 billion on its own.

(And AdAge estimates the ENTIRE hair market at $8 billion, but that includes unmeasured channels, which always makes me go hmmmm....)
