WARNING: Do not use if you are allergic to eggs!

In a bowl, mix 4 tbsp. of plain yogurt (not low-fat) and one egg.

After shampooing, pour the yogurt-egg mix onto your head and thoroughly massage it into your hair, working from roots to tips to make sure all your hair gets coated.

Leave mixture on for 5 to 10 minutes.

Rinse out well with lots of cool (not hot or warm) water. *This is very good for softening up dry hair and preventing fly-aways and frizzies., cold water closes the hair shaft*
