what is the global or US market size for shampoo

Hello awoo-ga,

To answer your specific question, according to "The World Bank
Report", global sales of shampoo in the United States in 1999 totaled
approximately 1.5 billion dollars. That works out to about $5.33 worth
of shampoo for every man, woman and child in the country.

That compares to sales in 1999 of about one billion U.S. dollars
annually in China (population 1,210,000,000 as of 1996), $800,000,000
in India (population 936,500,000 in 1995), and one billion dollars in
Brazil (population 160,750,000 as of 1995).

There is lots of market research addresing shampoo and hair care
products and their distribution. Unfortunately, it is generally in the
form of professionally prepared marketing reports that cost anywhere
from several hundred to several thousand dollars. Here is a good
source for such reports:

I hope this answer meets your needs. If not, just ask for
clarification.
