When I dye my hair, the color will either barely show up or fade after a few rinses. Keep in mind that I have blonde hair so any color shows up in my hair and it's not just from my hair being too dark.

I also never use hot tools on my hair or dye it often so my hair definitely isn't damaged. I dye my hair probably once every few years and it's not my full head, just a strip or my ends. I'm confused as to why this pink hair dye is barely showing up in my hair.
