Most hair dye boxes come with instructions that tell you exactly how long to leave the dye in, but let's be real, who actually reads those? It's like trying to assemble IKEA furniture without looking at the manual, it's not going to end well. Generally, permanent hair dye should be left in for around 25-35 minutes, while semi-permanent dye should be left in for around 20-30 minutes.
But here's the thing, every head of hair is different, so what works for your friend might not work for you. It's like trying to fit into a pair of jeans that fit your sister perfectly, it's just not going to happen. You need to take into account your hair type, length, and previous color treatments when deciding how long to leave the dye in.
