My aunt uses mayo as a hair conditioner. Why on earth would you put a mayo in your hair? Is there any validity to this?

In the world of beauty and personal care, a myriad of unconventional home remedies and DIY treatments have garnered attention over the years. From avocado face masks to sugar scrubs, it seems there’s no household ingredient that hasn’t been enlisted for cosmetic use.
One of the more unexpected items that some people, like my aunt, swear by is mayonnaise as a hair conditioner. This may sound unorthodox, or even unappealing, to numerous individuals, yet there is a rationale behind this pantry product’s leap into the hair care arena.

Understanding Mayonnaise and Hair Care
To get to the bottom of this slippery situation, let's deconstruct mayonnaise. At its most basic, mayo is an emulsion of oil, egg yolks, and either vinegar or lemon juice. Each of these ingredients has properties that could potentially benefit hair:
  1. Oil: Typically soybean or vegetable oil, this ingredient is rich in fatty acids and vitamins. It can provide moisture to dry hair, make it more pliable, and give it a glossy sheen.

  2. Egg Yolks: These are packed with proteins and nutrients like biotin, which can strengthen hair strands and promote hair health.

  3. Vinegar or Lemon Juice: Both vinegar and lemon juice are acidic, which can help in cleansing the scalp and balancing hair's pH levels, potentially reducing frizz and adding extra shine.
Does It Work and How?
These components of mayonnaise separately have recognized benefits for hair, so it’s not completely far-fetched that together they would serve as a conditioning treatment. The idea behind using mayonnaise for hair is that it can act as a deep conditioner, hydrating and nourishing the hair and scalp:
  1. The oil provides deep moisturization, which is especially beneficial for people with dry or brittle hair.

  2. The protein in egg yolk may help strengthen the hair shaft, reducing hair breakage and improving texture.

  3. The vinegar or lemon juice can help remove buildup from hair care products and impart a natural shine to the hair.
However, the effectiveness of mayonnaise as a hair conditioner can vary depending on your hair type and the quality of the mayonnaise used. A high-quality, oil-rich mayo is likely to yield better results than a low-fat or alternative mayo with preservatives and added ingredients.
How to Use Mayonnaise as a Hair Conditioner
If you’re curious or brave enough to give this a try, here’s a simple method to use mayonnaise as a hair conditioner:
  1. Start with clean, slightly damp hair.

  2. Apply mayonnaise starting from your scalp and work through to the ends.

  3. For an even application, comb through with a wide-toothed comb.

  4. Let it sit under a shower cap for 15-30 minutes.

  5. Rinse it out thoroughly with warm water and shampoo.
Some people like my aunt use mayonnaise treatment once a week, but the frequency should be adapted according to your hair type and the results you observe.
Considerations Before Slathering on Mayo
Putting mayonnaise in your hair is not entirely without reservations or potential pitfalls:
  1. The smell can be off-putting to some and might linger even after rinsing and shampooing.

  2. Mayonnaise can be too heavy for those with fine or oily hair, potentially leading to greasiness.

  3. Anecdotal evidence varies greatly, and there’s a lack of scientific research to back up the claims of the effectiveness of mayonnaise as a hair treatment.

In conclusion, while applying mayonnaise to your hair might seem odd, the ingredients do have properties that could potentially enhance hair health. For those seeking a natural, DIY approach to conditioning, it’s a readily accessible and inexpensive option to test out. Just like with any home remedy or beauty treatment, results will vary, and what works for one person might not for another. It could be worth a try if you're eager for a deep conditioning treatment and are willing to overlook the salad dressing scent.
