I've used Sun-In on my naturally dark hair.
I used to get my black hair bleached blonde every 7 weeks. It was a nightmare to upkeep, my hair was constantly fried and the colour didn't go with my complexion but I thought it looked hot. I kept it that way for 3 years.
I have used kool-aid to dye my hair.
I have used egg white as a face masque - it's great for tightening pores!
Vaseline instead of clear mascara is not cool, especially when you wear contacts.
I once left a depilatory on my legs for too long because it wasn't working. (I have fine hair.) It burned the skin on my knees.
Now, I have heard about eyelash implants, a new procedure plastic surgeons are trying on people who have had their eyelashes burned off in fires or something. I am seriously considering it when it gets cheaper.
