The deadline for filing a lawsuit against a hair relaxer product manufacturer depends on the statute of limitations in the state where you live. The best way to ensure you are properly informed about this deadline is to speak to an experienced attorney. It's always better to file sooner rather than later. The sooner you file, the less you risk running out of time and losing your chance to file a lawsuit. If you miss the deadline (statute of limitations), you will be unable to get compensated for your injuries. We would be happy to discuss the deadline based on your specific situation and advise you about the best time to file a lawsuit.
