The document discusses HLL's introduction of the Rexona deodorant brand in India in the 1990s. At the time, deodorants were a new product category and most consumers were unaware of body odor as a problem. HLL launched an educational marketing campaign to create awareness of body odor and position deodorants as a solution. They targeted young consumers aged 16-20 by making the product affordable and packaging it attractively. The campaign was successful in growing the deodorant market from 1000 tonnes to wider adoption. However, HLL chose not to target consumers over 40 due to factors like their resistance to new innovations and being less susceptible to social influences.
