What is Co-Washing Hair? The Complete Guide

You have probably heard the term “co-washing,” especially if you have curly natural hair. There have been many speculations on the subject of co-washing. Some feel that it is the holy grail of caring for curls, while others feel that they are better off without it. It can honestly be frustrating and confusing to figure out if co-washing is the best option for your own hair.

Before you come to any conclusions about co-washing, it’s best to evaluate all the facts. By examining the information in this article, you will be able to make an informed decision on whether or not to co-wash, and the best way to go about it.

We hope that this article will completely equip you with all the information you need about co-washing your hair!

What is Co-Washing?

Simply put, co-washing means washing with conditioner instead of shampoo. Essentially, you are using a cleansing conditioner to remove product and buildup from your hair without the use of shampoo, in order to maintain a healthy amount of moisture in your hair. 

Who Should Co-Wash?

Really, anyone can co-wash, but there are certain types of hair that thrive more when they are co-washed. This includes curly and/or dry hair.

The curlier the hair, the dryer it tends to be. Think about your curly hair strand like a roller coaster. The natural oils from your head have to travel down and around through lots of twists and turns to get to the ends of your hair, so it takes a bit longer to get there. Truth be told, you may have oily roots before your natural oils even have a chance to reach the ends of your hair.

If your hair is not curly, you may still benefit from co-washing. It can be beneficial for those with very dry hair regardless of the texture. This is especially true of those with long hair because just as is the case with curly hair,  the ends tend to lack moisture.

What are the Benefits of Co-Washing?

Benefits of Co-washing Hair

The main benefit of co-washing is that it is very moisturizing. Shampoo is more effective in thoroughly cleansing the hair but it can strip the hair of its natural oils, especially if it is being used too often.

Another benefit to co-washing is that it helps your colored hair stay vibrant for longer. Every time you wash your hair with shampoo, your hair color fades just a little. When you cleanse with conditioner, your color will fade less, thereby allowing you to keep your vibrant hair color for as long as possible.

Finally, my favorite benefit of co-washing is the fact that it allows you to restyle hair without shampooing it. If your hair is fairly clean but it’s starting to look really wonky, you may have no other choice than to completely soak it and re-style it. Co-washing gives you the opportunity to hydrate your hair and freshen your style as often as you’d like.

What are the Cons of Co-Washing?

Cons of Co-washing Hair

Along with the benefits of co-washing, there are also some negative aspects to keep in mind. The truth is that, while co-washing can help to remove buildup from the hair, it doesn’t cleanse the hair and scalp as thoroughly as shampoo.

If you completely rely on co-washing to cleanse your hair, you will most likely not be removing all the product and environmental buildup on your hair. This can lead to an itchy/sore scalp and, in extreme cases, hair loss.

Of course, I am not saying this to scare you from using a co-wash! There is definitely a good purpose for co-washing if used in between shampoos. 

How Often Should You Co-Wash?

This question has spurred much debate in the last few years. Some feel that you should never use regular shampoo, and simply stick to co-washing. Most hair stylists will disagree with this statement.

As stated earlier, there are many benefits of co-washing, including adding extra hydration to your hair, preserving your color for longer, and being able to restyle your hair between shampoos. However, the negative side of co-washing is that it doesn’t cleanse your hair as thoroughly as shampooing. By finding a good balance of the two, you can achieve your ideal hair. 

As a hair stylist, I recommend that you shampoo your hair anywhere from twice a week to once every two weeks. Co-washing can be done as much as once a day. Therefore, co-washing is a great thing to do in between shampoos, either to restyle your hair or to postpone shampooing for a bit longer.

If you are someone who needs to soak and restyle their hair every single day, you should definitely be co-washing every day instead of shampooing every day. You will notice that your hair is softer, shinier, and altogether healthier.

What Products Should be Used for Co-Washing?

While it is possible to co-wash with a regular conditioner, it’s best to co-wash with a product specifically formulated for that purpose. With the popularity of co-washing rising, it is not difficult to find an abundance of co-washes on the market.

Another thing to keep in mind when shopping for a co-wash is your specific hair type. If your hair is very thick and/or coiled, you may need a thicker, richer, more moisturizing co-wash. If your hair is fine, thin, or easily weighed down, you may best be looking for a lighter co-wash.

No matter what your hair type, there is a co-wash out there for you!

What is the Best Way to Co-Wash?

Steps to Co-washing Hair

Now that you know pretty much all there is to know about co-washing, you need to know how to do it! (Of course, it’s always best to read the directions for your specific product before using it.) By consulting the guide below, you will be able to hydrate your hair and keep it feeling fresh.

Step-by-Step Guide to Co-Washing Your Hair:

  1. Select the conditioner or co-wash product that you are going to use.
  2. Completely soak your hair with warm/hot water.
  3. Apply the conditioner or co-wash to your scalp and hair.
  4. Rub the conditioner/co-wash into your scalp as you would a shampoo. Really scrub your scalp and hair to loosen up any dirt or buildup.
  5. Rinse out the conditioner/co-wash with warm/hot water. Make sure to rinse it thoroughly until no conditioner/co-wash remains in your hair.
  6. Repeat steps 3-5.
  7. Apply your regular conditioner to the mid-lengths and ends of your hair to add extra hydration. Leave it on for 5 minutes.
  8. Rinse out the conditioner with cool water.
  9. Gently squeeze the excess water out of your hair and pat dry with a microfiber towel. Style as desired.

After you have co-washed your hair, be sure to pay attention to how your hair looks and feels. If it is too greasy, you may need to skip the step of conditioning it again after you co-wash.

If it’s still dry, you may need to consider applying a deep hydration mask to your hair. Everyone’s hair is different, so it may take a bit of trial and error to figure out what works best for you!

What are Some Common Mistakes to Avoid When Co-Washing?

There are a few common mistakes to avoid when co-washing your hair. We will discuss those common mistakes below, and how you can avoid them.

Applying a Co-Wash as You Would a Regular Conditioner

Common Mistakes While Co-Washing - Using as regular conditioner

In order to cleanse your hair with conditioner, you have to scrub it into your scalp and hair. This is what loosens up dirt and oils. If you just let it sit on your hair like you would a regular conditioning treatment, you will not accomplish much.

Therefore, you can avoid this mistake by treating your co-wash as you would a shampoo. Use your fingers to really scrub!

Completely Replacing Shampoo with a Co-Wash

As stated previously in this article, co-washing should not completely replace shampooing. It should simply supplement it. Therefore, it is important that you still shampoo your hair regularly to eliminate buildup on your hair and scalp.

If your hair starts to feel weighed down, or your scalp is greasy, sore, or itchy, it’s time for a good shampooing.

Only Applying Your Co-Wash Once and Then Rinsing

Common Mistakes While Co-Washing - Doing it Once

Applying your co-wash once and then rinsing it out is not going to be as effective as you may hope. If you are determined to cleanse your hair as much as possible with your co-wash, apply it at least twice. After you apply it to your hair each time, scrub it into your hair and scalp, and rinse it out completely.

Not Rinsing Your Co-Wash Out Completely

Not completely rinsing out your co-wash can make your co-washing process quite ineffective. The point of co-washing is to gently loosen any dirt or buildup on your hair so that it can be rinsed off. If you are not rinsing the co-wash out thoroughly, you aren’t cleansing your hair.

Rinse out your co-wash thoroughly with warm/hot water. If you still need more moisture added to your hair, you can always apply a regular conditioner to your mid-lengths and ends after you have rinsed out the co-wash.

Co-washing is a great way to refresh, cleanse, and moisturize your hair! When done with the right products and methods, it can benefit your hair and bring you one step closer to achieving the shiny, bouncy, and healthy hair of your dreams!
