Ooh, I got one: I will NEVER pre-poo overnight with raw eggs. I should have been cautious because raw eggs make me sick. Here's the story.
I was a senior in high school and my new Seventeen came in the mail. They had an article about healthy hair care and said if your hair was feeling damaged, try mixing a raw egg in your shampoo or conditioner. They also said for really damaged hair, mix a raw egg with vegetable oil and let it set overnight. When you wake up, wash and you will have beautiful, shiny hair.
So I did that and slept with a plastic cap. When I woke up, I instantly smelled the eggs and saw that the cap had partially come off my head. My brand new satin pillowcase was rock hard with dried egg. I then take the cap off and my hair is just as hard as the pillowcase. And the smell!! OMG!! I thought I was gonna die right there.
I then shampooed my hair like 3 times, but with the nicest smelling shampoo (like Herbal Essences and Pantene), but my hair still smelled like eggs. I then let my mom rollerset it, which took forever because my hair was dried out and brittle because of protein overload. The hair STILL smelled. So I sprayed some perfume in my hair, which covered it a bit but I still smelled it. I guess I'm just sensitive to eggs becuase the last 2 times my mom cooked eggs for me, I threw it up. (she cooks them runny).
NEVER EVER AGAIN!!
a sad farewell to red hair.
