Should You Be “Reverse Washing" Your Hair? Here’s What the Pros Say

What Is Reverse Washing, Anyway?

Simply put, reverse washing flips the hair-washing process on its, well, head. “Reverse hair washing involves conditioning hair prior to shampooing,” explains board-certified dermatologist Audrey Kunin, MD. “It helps deeply condition hair without weighing it down.” It’s similar to co-washing, in which hair is washed only with conditioner (or a specific co-washing cleanser), but has the added step of shampooing the hair after as well. Co-washing is also more commonly used on natural hair types, while reverse washing is better suited to finer hair.

Who Should Be Reverse Washing Their Hair?

Reverse washing is an option for several hair types and conditions. According to NYC-based hair stylist Alan David, those with damaged hair due to color, heat, or dryness can benefit from this method. “It’s a great way to make the hair soft so you can really get the root clean with shampoo,” he says. Kunin adds that those with fine hair or an oily scalp can also benefit from reverse washing.

The Pros and Cons of Reverse Washing

There are several benefits to reverse washing, from detangling strands to preventing flat hair from too much product build-up. “It keeps dry, brittle hair soft so that while you're shampooing, you don’t tangle and knot,” explains David. According to Kunin, reverse washing is gentler on fine and thin hair than traditional washing “and helps remove conditioner residue from scalp.”

And although there are no major side effects to reverse washing, it’s important to note that it may not be the method of choice for all hair textures or types. “Some curls benefit from this, but it’s better to use [no suds] shampoo,” says David, adding that, “Reverse shampooing is really only good for very dry, damaged hair of all hair textures.”

How to Reverse Wash Your Hair

You can use the same hair conditioner for steps one and three, or try using a deep conditioner or hair mask before washing hair, followed by a lightweight conditioner.

1. Condition.

Apply a conditioner, such as NATURELAB.TOKYO Repair Treatment Masque, to wet hair, avoiding the roots (especially if you have oily hair or an oily scalp). Leave on for up to five minutes, then rinse.

2. Shampoo.

Next, work a moisturizing shampoo, such as IGK Hot Girls Hydrating Shampoo into a rich lather to cleanse hair and remove product build-up without stripping hair of its natural oils.

3. Condition again (maybe).

If you have dry hair, “It’s important to still condition after you shampoo,” says David. If you’re afraid of weighing down hair, try a lightweight conditioner, such as TRESEMMÉ Pro Pure Damage Recovery Conditioner for Damaged Hair.
