Answer:
Gillette in India
The failure of the Vector was caused by the fact that Indian men have longer and thicker hair, which the lack of earlier research in the targeted demographic segment did not discover.
Explanation:
Since Indian men have longer and thicker hair than the local consumers of Gillette's razor products in America, an earlier research would have uncovered the fact. Thereafter, the discovery would have been incorporated into the design and production of Vector for the Indian market. No wonder, with its Mach 3 Turbo razor, Gillette overcame its initial inertia and handicap and made a success of the razor business in India.
