Mayonnaise

Yes, you read it right. The condiment you love to dump all over your hotdogs and fries can make your hair beautiful. Weird as it may sound, plain mayonnaise is an effective hair care product. It’s made from oil, eggs and vinegar, all of which can nourish the hair, give a protective covering and close the cuticle layer. If you’ve got some left over from making your potato salad, feel free to use it on your crowning glory.
Mayonnaise can help you get rid of split ends and dry hair. Put a dollop on the palm of your hand and massage to your head. Leave it on for five minutes, then take a bath to remove it.

Mayonnaise is also a good conditioner. Apply it to your wet hair, and then comb through to even it out. Cover with a plastic cap, then leave it on for 20 to 30 minutes while staying under a warm dryer. Rinse it off afterwards. Your hair will feel smooth and more manageable.
As effective as it may be, there’s one disadvantage when using mayonnaise: it can be pretty smelly. The trick is to wash it out thoroughly. Work your way through the scalp and use your fingers to rub it all out, so you won’t have to smell like salad dressing all day.
