Can Mayonnaise Make Your Hair Straight?

Mayonnaise itself cannot straighten hair, but mayonnaise can help straight hair look straighter by taming frizz. Mayonnaise contains a lot of oils to moisturize frizzy hair, helping the straight hair stay straight.

Moreover, mayonnaise has protein since mayonnaise contains eggs, which means the proteins in mayonnaise can strengthen brittle straight hair.

However, it is important to note that mayonnaise is not a cure for frizzy hair since you need to make sure you do not do other things that cause frizzy hair.

For instance, mayonnaise will only be a band-aid solution to frizzy hair if you use heated hair styling tools regularly, so you may need to lessen how often you apply heat to your hair.

How Do I Use Mayonnaise To Straighten My Hair?

You can use mayonnaise to straighten your hair by using the mayonnaise as a hair mask, similar to how you would use a deep conditioner.

You can use mayonnaise by itself, but some people opt to add an egg to their mayonnaise for extra protein.

Typically, a cup of mayonnaise should be more than enough, but you can use more or less depending on your hair’s length and thickness. At this point, you may add your egg and mix the egg into the mayonnaise well.

Apply the mayonnaise into your hair thoroughly, coating each strand. If desired, you can place the mayonnaise on your scalp as well.

Allow the mayonnaise to sit on your hair for 15-30 minutes then use a gentle shampoo and water to rinse out the mayonnaise very well, making sure to not leave any mayonnaise behind.

It is not recommended to leave mayonnaise in your hair for longer than 30 minutes because the mayonnaise can begin to spoil, which can smell and feel very unpleasant.

Typically, you can use mayonnaise as a hair mask once a week, but healthier hair types may only need to use mayonnaise hair masks 1-2 times a month.

Generally, you should not use mayonnaise on your hair more than once a week because you will not notice major benefits and your scalp can get irritated.

Moreover, mayonnaise is not meant to replace proper hair care products specifically created for hair.
