Egg and/or mayonnaise treatments are used to help restore moisture and shine to dull hair. Mixing the two ingredients together is a natural, cheap, easy and effective method for deep conditioning. The treatments are meant for dry or normal hair, but are too heavy for oily hair. People with oily hair can use raw and whipped eggs as a homemade conditioner, but should skip the mayonnaise.
While any kind of raw egg can help heal hair, stick with fresh farm eggs for the best results. Eggs not only contain protein and fatty acid to help nourish hair, they contain vitamins A, D and E, which are important to basic hair health. Look for eggs with thick shells and rich yolks, as these are marks of quality. An egg with a thin shell or pale yolk will contain far fewer nutrients than what you want for great hair.
Mayonnaise is a mixture of eggs, oil and vinegar. Eggs contain protein, fatty acids, vitamins and minerals essential for rejuvenating hair. The oil helps moisturize and protect your hair while adding a deep shine. Vinegar gently removes mineral deposits and balances the pH level of your hair. These three ingredients mixed together create a balanced conditioner perfectly suited for your hair. Remember to use real mayonnaise for your hair. Mayonnaise-style substitutes use too many chemicals and preservatives to be good for your hair.
Eggs and Mayonnaise
The point of adding fresh egg to an already egg-based mayonnaise is that it gives your hair a perfect balance of the fresh nutrients it needs. Once an egg has been emulsified and whipped into mayonnaise, it loses many of its vitamins and minerals. By adding the fresh egg to the hair treatment, you restore those lost nutrients.
Create a homemade egg and mayonnaise treatment for shoulder-length hair by whipping together one egg and 1/3 cup mayonnaise in a small bowl. Spread the mixture on damp or dry hair and massage gently into the scalp. Cover your hair with a plastic shower cap and let the mixture set for 15 to 30 minutes. Use a gentle shampoo to remove the treatment, rinse well and let your hair dry.
If you're allergic to eggs or any of the ingredients used in mayonnaise, don't use this type of hair treatment. It doesn't matter if the allergy only seems to be linked to ingestion of the item, you are still at risk of an allergic reaction from skin contact. If you suffer from severe acne, you may also want to skip the treatment, as it is heavy in oil.
