If you’ve ever wondered what order to apply your hair products, you’re definitely not alone. In fact, it’s one of the most common questions I get behind the chair. Somewhere between the leave-in conditioner, heat protectant, mousse, curl cream, hair oil, and hairspray, it’s easy to wonder… does the order actually matter?

The short answer?

Yes. More than most people realize.

One of my clients laughed recently and said, “I think I own all the right products…I just have absolutely no idea what order I’m supposed to use them.”

Honestly? I hear some version of that almost every week.

Some clients pull an entire bag of products out of their purse and ask me to help them figure out what each one does. Others have a bathroom cabinet full of bottles they’ve collected over the years because someone on Instagram swore they were life changing.

Here’s the good news.

You probably don’t need more products!

You just need your products to work together.

Think about getting dressed. You wouldn’t put your shoes on before your socks or your jacket on before your shirt. Hair products work the same way. Each one has a purpose, and when you apply them in the right order, they perform the way they were designed to.

Today, I’m going to show you exactly how I layer products behind the chair, explain why the order matters, and help you build a routine that’s simple, effective, and works for your hair, not someone else’s.

Why the Order Matters

One of the biggest mistakes I see isn’t someone buying the wrong product.

It’s someone using a great product at the wrong time.

Hair products are designed to do different jobs.

Some are meant to absorb into the hair.

Some create hold.

Some seal the hair.

Some protect it from heat.

If you apply a heavier product first, it can block lighter products from doing their job.

It’s a little like painting a wall. You wouldn’t apply the top coat before the primer.

The same idea applies to your hair.

As a general rule, start with products that need to get inside the hair and finish with products that stay on the outside.

Once you understand that, building a routine becomes much easier.

Step 1: Leave-In Conditioner

After washing your hair and gently towel drying, the very first product I usually reach for is a leave-in conditioner.

Why?

Because damp hair is like a sponge.

It’s ready to absorb moisture.

A good leave-in conditioner helps:

• Add lightweight hydration
• Reduce tangles
• Protect the hair while brushing
• Improve softness
• Create a smoother foundation for every product that comes next

If you have long hair, color-treated hair, or curls, this is one product I rarely skip.

Rachel’s Pick

Nº.5 Leave-In Moisturize & Mend Leave-In Conditioner

I love this one because it works on almost every hair type. It detangles beautifully, adds moisture without feeling heavy, and layers well with other styling products.

Step 2: Treatment Serums

Once your leave-in conditioner has been distributed through the hair, it’s time for any treatment products.

These are products that are designed to improve the health of your hair while also offering styling benefits.

One of my favorites is Olaplex No. 9 Bond Protector Nourishing Hair Serum.

This has quietly become one of those products I reach for over and over behind the chair because it does so many jobs without making the routine feel complicated.

It helps:

• Protect against heat up to 450°F
• Defend against pollution
• Reduce static
• Add shine
• Improve softness
• Help prevent tangles

The best part?

It layers beautifully under almost every styling product I use.

How to Use It

Apply one to three pumps to clean, damp hair.

Start around your ears and work through your mid-lengths and ends.

Comb it through so every strand gets an even amount before blow drying or diffusing.

If your hair is fine, start with one pump.

You can always add more next time.

Rachel’s Pick

If I had to recommend just one heat protectant to almost everyone who sits in my chair, the Olaplex No. 9 Bond Protector Nourishing Hair Serum would probably be it.

Step 3: Styling Products

Now it’s time to decide what you actually want your hair to do today.

This is where your routine becomes personalized.

I always tell clients there’s no such thing as the “best” styling product. There’s only the best product for your hair typeand your goal that day.

Here’s a simple way to think about it:

Curl Cream

Best for curly and wavy hair that needs moisture and definition.

Curl creams help enhance your natural curl pattern while reducing frizz. If your curls tend to feel dry or fluffy, this is usually where I’d start.

Mousse

Best for fine hair, wavy hair, or anyone looking for volume and longer-lasting hold.

A good mousse gives your style memory without making your hair crunchy. I often recommend mousse to clients who say, “My curls fall flat halfway through the day,” or “My blowout never lasts.”

Volumizing Spray

Best for fine or flat hair.

These products are usually applied at the roots before blow drying to create lift without making the hair feel sticky. If your biggest complaint is, “My hair has no body,” this is often a better choice than adding more hairspray later.

Blowout Cream

Best for medium to thick hair that’s being blow dried smooth.

Blowout creams help create a sleek finish while making it easier to brush through the hair during drying. They’re great for anyone who loves that fresh-from-the-salon look.

Smoothing Cream

Best for thick, coarse, frizz-prone, or unruly hair.

These products help relax the hair, tame flyaways, and control humidity. If your hair seems to double in size the moment you step outside, a smoothing cream can make a huge difference.

One thing I want to point out…

More products don’t automatically equal better hair.

In fact, one of the biggest mistakes I see is someone layering four different styling creams because they’re trying to get the “perfect” result.

Usually all they’ve done is make their hair feel heavy.

I always recommend starting with one styling product that solves your biggest concern.

Need more volume? Reach for a mousse or volumizing spray.

Need smoother hair? Try a blowout or smoothing cream.

Want better curls? Start with a curl cream.

Once you’ve mastered one product, you can always build from there if your hair needs it.

Step 4: Dry and Style Your Hair

Now comes the fun part.

Blow dry.

Diffuse.

Air dry.

Whatever works best for your hair.

By this point, everything underneath is working together.

Your leave-in is helping with moisture.

The Olaplex No. 9 is protecting against heat.

Now your styling products are creating shape and hold.

Now all you have to do is bring it to life.

Step 5: Finish the Look

Once your hair is completely dry, it’s time for the finishing touches.

Unlike your leave-in conditioner or treatment serum, these products aren’t meant to absorb into the hair. Their job is to enhance the style you’ve already created.

Think of them as the accessories.

You wouldn’t put on your earrings before getting dressed, and you wouldn’t apply lipstick before washing your face. Finishing products are the last step because they’re designed to perfect your look, not build it.

Here’s a quick guide to what each one does.

Hair Oil

Best for: Dry, dull, frizzy, or damaged hair.

A lightweight hair oil adds shine, smooths flyaways, and helps dry ends look healthier. Focus on the mid-lengths and ends, and remember—a little goes a long way. If your hair looks greasy after using oil, you’re probably using too much.

Texture Spray

Best for: Fine to medium hair that needs volume or a lived-in look.

Texture spray creates separation, movement, and body. It’s perfect if you’re going for beachy waves, messy buns, or that effortless “second-day hair” look. If your hair tends to fall flat, this is one of my favorite finishing products.

Shine Spray

Best for: Hair that looks dull after styling.

If you’ve ever left the salon wondering why your hair looked shinier than when you style it at home, this is often the missing step. A light mist of shine spray can instantly make healthy hair look even healthier. Just keep it away from your roots so your style doesn’t look oily.

Flexible Hairspray

Best for: Holding your style without making it stiff.

Not all hairsprays leave your hair crunchy. Flexible formulas help your style last while still allowing movement. It’s my go-to for everyday styles because you can brush through it and still touch your hair without feeling like you’re wearing a helmet.

Finishing Cream

Best for: Thick, coarse, curly, or frizz-prone hair.

Finishing creams help tame flyaways, soften the ends, and smooth the overall shape of your style. They’re especially helpful on humid days or anytime your hair needs a little extra polish without adding hold.

Remember just like with the styling products…

Not every hairstyle needs every finishing product.

If your hair already looks smooth and shiny, you probably don’t need both a hair oil and a shine spray.

If your curls are holding beautifully, you may not need hairspray.

Choose the product that solves the problem you actually have.

One pump of oil can completely transform dry ends.

One quick spray can give fine hair the texture it’s been missing.

The goal isn’t to use more products.

It’s to use the right product for the result you want.

That’s how you get hair that looks effortless instead of overdone.

The Biggest Mistakes I See Behind the Chair

Using Hair Oil Instead of Heat Protectant

Hair oil and heat protectant are not the same thing.

Hair oil helps smooth and soften.

Heat protectant helps reduce damage from high temperatures.

They each have a purpose.

Applying Hair Products to Soaking Wet Hair

Unless the directions specifically tell you otherwise, I prefer applying most leave-ins and styling products after gently towel drying.

If your hair is dripping, you’re diluting the product before it even has a chance to work.

Putting Everything on Your Roots

Your scalp usually doesn’t need more moisture.

Your ends almost always do.

Most styling products belong from your ears down.

Using Too Much Product

This one is so common.

People assume if one pump works…

Three pumps must be even better.

Unfortunately, hair doesn’t usually work that way.

Most products are highly concentrated.

Start small.

You can always add more.

Taking product away is much harder.

“But Rachel…My Hair Still Feels Heavy.”

This is where I start asking questions.

Does your hair actually need different products?

Or does it simply have months of buildup sitting on it?

Sometimes people buy new shampoo.

Then new conditioner.

Next a new leave-in.

After that a new styling cream.

When really…

The products weren’t the problem.

The buildup was.

If your hair feels coated, waxy, dull, or like your products have stopped working, I highly recommend reading my article What Is a Chelating Treatment?

Sometimes healthier hair isn’t about buying something new.

Sometimes it’s about removing what’s already there.

My Everyday Routine Behind the Chair

If someone sat down and asked me to build them a simple routine, it’d probably look something like this:

1. Shampoo
2. Conditioner
3. Leave-In Conditioner
4. Olaplex No. 9
5. Styling Product
6. Blow Dry or Diffuse
7. Hair Oil (if needed)
8. Hairspray or Texture Spray

That’s it.

No twelve-step routine.

No products fighting each other.

Just a routine where every product has a purpose.

My Final Thought

The beauty industry is really good at convincing us we need to be applying more hair products.

But after more than 21 years behind the chair, I’ve learned something.

Great hair usually isn’t about owning more products.

It’s about understanding the ones you already have.

When each product has a job, your routine becomes simpler.

Your hair becomes more predictable.

And suddenly, getting ready in the morning feels a whole lot easier.

That’s always my goal.

Not to sell you ten bottles.

To help you make the bottles you already own work better.

Frequently Asked Questions

Can I use hair oil before blow drying?

Generally, no. Hair oil isn’t designed to replace a heat protectant. If you’re using heat, apply a dedicated heat protectant first. Save your hair oil for after styling unless the specific product directions say otherwise.

Do I need every product in this routine?

Not at all. A great routine doesn’t have to be complicated. Start with the basics and add products only when they solve a problem you actually have.

Should I apply products to wet or damp hair?

Most leave-in conditioners, heat protectants, and styling products perform best on clean, towel-dried hair. Hair that’s dripping wet can dilute products and make them less effective.

How do I know if I’m using too much hair product?

If your hair feels heavy, greasy, sticky, or flat shortly after styling, try cutting your usual amount in half. You might be surprised how little product your hair actually needs.
