So, what's the deal with hair dye, anyway? It's like, a science experiment for your locks! The dye works by penetrating the hair shaft and depositing color - it's like a little color bomb going off in your hair!
But, here's the thing: if you leave the dye in for too long, you can end up with over-processed hair that's all dry and damaged.
