Ever wondered if you should use shampoo or conditioner first? You’re not alone! A lot of people do it without thinking, but the order actually matters. It can change how your hair looks and feels.
Using the wrong order can make your hair greasy, dry, or flat. The right way can give you soft, shiny, and healthy hair. But here’s the thing—different hair types need different methods!
What if you could get the perfect balance? Less frizz, more volume, and hair that stays fresh longer? By understanding how shampoo and conditioner work, you can choose the best routine for your hair type.
Let’s break it down. We’ll explain both methods—shampoo first or conditioner first—so you can find what works best for you.
Why Does the Order Matter?
The order in which you use shampoo and conditioner affects how clean, hydrated, and healthy your hair looks and feels. Shampoo cleans your hair, but conditioner helps to restore moisture and smooth it out. Using them in the right order can prevent buildup, dryness, or damage.
Common Misconceptions About Shampoo and Conditioner Usage
Many people think shampoo is the most important part of hair washing, so they focus on it the most. But conditioner is just as crucial—especially if you have dry or damaged hair. Using conditioner first or second can impact how well your hair is hydrated and styled.
Shampoo vs. Conditioner: Understanding Their Roles
Both shampoo and conditioner have different jobs. Let’s quickly review what each one does:
What is Shampoo?
Shampoo is a cleanser for your hair. It has ingredients that remove oil, dirt, and products from your scalp and strands. Some shampoos are designed to help with oily hair, while others are more suited for dry hair.
Different hair types need different shampoos:
- Oily Hair: Look for clarifying or balancing shampoos.
- Dry Hair: Try moisturizing or hydrating shampoos.
- Fine Hair: Use volumizing shampoos.
- Conditioner: Restores moisture and smoothens hair. It helps to hydrate and protect hair from the dryness that shampoo might cause.
What is Conditioner?
Shampoo can leave your hair dry because it strips away oils. Conditioner is the product that makes your hair soft and hydrated. It locks in moisture, smoothens the cuticle (the outer layer of hair), and helps your strands feel silky.
Apply conditioner only to the ends of your hair. Avoid your scalp unless it’s specifically a scalp conditioner. Leave it on for a few minutes to let it soak in.
Difference Between Shampoo and Conditioner
| Shampoo | Conditioner |
| Cleanses hair and scalp | Moisturizes and softens hair |
| Removes dirt, oil, and buildup | Repairs and nourishes hair |
| Comes in different formulas (volumizing, moisturizing, etc.) | Can be thick or lightweight depending on the hair type |
The Right Order: Shampoo or Conditioner First?
Washing hair sounds simple, but the order you use shampoo and conditioner matters. Some people always shampoo first, while others apply conditioner first. Both methods have benefits, depending on your hair type and needs.
Here’s where the fun begins. There are two main ways to use shampoo and conditioner: the traditional method and reverse washing.
Shampoo First, Then Conditioner – The Traditional Method
Most people shampoo first because it cleans the hair and scalp. Shampoo removes dirt, oil, and product buildup. After that, conditioner adds moisture, which makes hair soft and smooth. This method is best for:
- People with oily hair (it removes excess grease)
- Those who use a lot of hair products (it clears buildup)
Most hairstylists recommend shampooing before conditioning because it’s simple, effective, and works for a wide range of hair types. Shampoo opens the hair cuticle, which allows the conditioner to soak in better. It’s still the go-to for most people!
But shampoo can also strip too much moisture, especially if your hair is dry, damaged, or fine. That’s where reverse washing comes in.

Conditioner First, Then Shampoo – Reverse Washing
This method flips things around. Instead of shampooing first, you apply conditioner first to protect your hair from drying out. Then, you shampoo to clean the scalp without removing too much moisture.
Reverse washing is great for:
- Fine hair (it prevents conditioner from making hair flat)
- Dry or damaged hair (it locks in hydration before shampooing)
- Greasy hair (it keeps hair moisturized without making it oily)
- Frizzy hair (it helps smooth frizz by locking in moisture and preventing dryness).
Conditioning first creates a protective layer so shampoo doesn’t strip away too much oil. This method also adds volume because shampoo washes away any extra conditioner, which ultimately prevents hair from feeling heavy or greasy.
There are other benefits of reverse washing:
- Protects hair from heat damage – Conditioner first acts like a barrier, reducing damage from styling tools.
- Prevents winter dryness – In cold weather, hair loses moisture faster. Reverse washing keeps hair from becoming too dry.

Which Method is Suitable for Oily or Greasy Hair?
If your hair gets oily fast, shampoo first. This removes grease, dirt, and buildup, leaving your scalp fresh. Then, use a light conditioner only on the ends to avoid extra oil.
But if your hair feels greasy yet dry at the same time, try reverse washing. Conditioner first adds moisture without making the scalp oily, and shampoo after removes excess grease. If your hair looks flat or heavy, reverse washing can add volume.

Shampoo and Conditioner 2-in-1 – A Quick Option
If you’re in a rush, you can use a 2-in-1 shampoo and conditioner. These products clean and hydrate at the same time. But they’re not great for dry or damaged hair because they don’t provide deep moisture.
Choosing the Best Method for Your Hair
| Hair Type | Best Washing Method |
| Oily Hair | Shampoo First |
| Normal Hair | Shampoo First |
| Fine Hair | Reverse Washing |
| Dry Hair | Reverse Washing |
| Curly Hair | Co-Washing (Conditioner-Only) |
| Men’s Hair | Usually Shampoo First |
| Black Hair | Conditioner First |
| 4C Hair | Conditioner First |
If you have curly or chemically treated hair, co-washing (washing with just conditioner) can help keep hair soft. But you’ll need to use clarifying shampoo once a month to avoid buildup.
You might wonder whether there is any scientific proof supporting reverse hair washing or co-washing methods.
There isn’t any scientific proof yet that shows reverse hair washing or co-washing methods are safe or work better, or how often you should use them. If your hair feels heavy, flat, or greasy after using conditioner, you might want to try using conditioner before shampooing.
Potential Problems with Alternative Methods
Trying new hair-washing methods can be great, but they also come with some issues. Let’s break them down in simple words.
Reverse Washing Can Cause Buildup
If you condition first, then shampoo, you need to rinse really well. If you don’t, conditioner can build up on your hair over time. This can make your hair feel heavy, greasy, or even sticky. It might also lead to a dull, flat look instead of soft and bouncy hair.
To avoid this, don’t overuse conditioner and always rinse thoroughly. Also, once in a while, use a clarifying shampoo to remove any leftover buildup.
Co-Washing Can Make Your Scalp Oily
Co-washing means washing hair with only conditioner—no shampoo. This is great for curly, dry, or damaged hair because it locks in moisture. But there’s one problem: conditioner doesn’t clean the scalp as well as shampoo does.
Over time, your scalp can get oily, itchy, or even flaky because dirt and oil aren’t properly washed away. This can also lead to blocked hair follicles, which isn’t good for hair growth.
To fix this, you can use a clarifying shampoo once a month to clean your scalp properly while still keeping your hair moisturized.
Wrapping Up
There’s no one-size-fits-all answer. Whether you shampoo or condition first depends on your hair type and what you want to achieve. In general:
- Shampoo first if you have oily hair or product buildup.
- Condition first if your hair is fine, dry, or damaged.
