Gillette is to close two UK factories and move production to Eastern Europe in a bid to cut costs.
Gillette hope to shave some costs with the factory move
The world's biggest razor blade maker said the closures would mean that at least 415 UK jobs will go over the next four years.
Plants in both Middlesex and Hertfordshire will be affected.
The moves are part of a wider restructuring that will affect up to 1,500 jobs as Gillette builds a new factory in a cheaper location.
The move follows the firm's review of its blade and razor operations in Europe and Russia.
But the company was unable to say how much money the switch would save, saying it would provide cost-saving estimates at a later date.
Gillette also said it would decide where it would build the new Eastern Europe facility by early next year.
The new plant will produce disposable razors and other shaving products, as well as package and distribute all Gillette blade and razor products in Europe.
In addition, production of its Sensor shaving range will move to the plant from their current manufacturing base in Berlin.
The Boston-based firm said it would also be moving some production from Russia to the Czech Republic.
Spokesman Eric Kraus said that all of the changes would affect between 1,200 to 1,500 jobs.
Gillette, which also produces batteries and Oral-B dental products, employs around 30,300 people.
