Adding raw egg to your hair - learn how to do it

Raw egg is supposed to do a lot of wonders to your hair; my wife was wondering what is the exact process to add raw egg to hair since it seems a bit yucky and messy. I looked around and found these articles that helped:

To reap the benefit of healthier hair provided by eggs, apply raw eggs to your hair regularly. Crack at least 2 eggs into a bowl and mix thoroughly. For longer hair, you may need more eggs. Massage the mixed eggs onto dry hair. Make sure to really saturate your hair. This can get messy, so you may want to do it over the bathroom sink. Allow 15 minutes for your hair to absorb the eggs. Then rinse your hair thoroughly with cold water only. Cold water not only closes the hair follicle, but it won't cook the egg as warm or hot water can. After rinsing, shampoo as usual.
