Does hair spray go bad?

Hairspray does not inherently "go bad" in terms of spoiling or losing effectiveness over time, provided it is stored according to the manufacturer's instructions. However, excessive use of hairspray, especially those containing ethanol or harsh chemicals, can contribute to hair damage, including dryness, brittleness, and potential buildup leading to reduced shine and increased susceptibility to breakage.

Key points regarding hairspray usage include:

1. Choose hairsprays without ethanol, which can be drying and irritating to the scalp.
2. Regularly cleanse your hair to remove product buildup.
3. Avoid over-brushing hair that's coated with hairspray, as it can weaken the hair cuticles and make them prone to breakage.
4. Use a hairspray containing vitamin E or other nourishing ingredients to maintain hair health.
5. Avoid inhaling hairspray directly, as it may have negative effects on respiratory health if used excessively and inhaled.

In summary, hairspray does not "go bad" if stored properly, but its misuse can lead to hair damage and potential health concerns. It's essential to choose the right products and use them in moderation for healthy hair maintenance.
