Keratin Hair Treatments: Everything You Need to Know Before Booking

Keratin Hair Treatments: Everything You Need to Know Before Booking

Smooth, glossy, manageable hair sounds simple—but for anyone who battles frizz, humidity, excessive styling time or unruly hair every morning, it can feel anything but simple.

That's why keratin smoothing treatments have become one of the most popular professional salon treatments.

But what exactly does a keratin treatment do?

Does it permanently straighten your hair?

Can you still curl your hair afterwards?

How long does it last?

And importantly, are all keratin treatments the same?

At Chroma Hair & Co in Highgate Hill, Brisbane, we believe clients should understand exactly what's being used on their hair and what results they can realistically expect.

Here's everything you need to know before booking a keratin smoothing treatment.

What Is a Keratin Hair Treatment?

A keratin treatment is a professional smoothing service designed to make hair smoother, more manageable and less prone to frizz.

Despite commonly being called "keratin straightening", the goal isn't necessarily to make every client's hair completely straight.

Instead, smoothing treatments can help:

• Reduce frizz

• Improve manageability

• Reduce styling time

• Smooth the hair

• Improve softness and shine

• Make blow-drying easier

• Relax unwanted volume

• Create a more polished finish

The final result depends heavily on your natural hair type, condition and desired outcome.

For some clients, the biggest difference is straighter-looking hair.

For others, it's simply being able to walk outside on a humid Brisbane day without their beautifully styled hair immediately becoming frizzy.

Keratin Smoothing vs Permanent Straightening

This is an important distinction.

A keratin smoothing treatment isn't the same as chemical permanent straightening.

Traditional permanent straightening changes the structure of the hair to create a permanently straighter result on the treated section.

Keratin smoothing is semi-permanent.

Over time, the smoothing effect gradually reduces and your natural texture returns.

That makes it an attractive option for clients who want smoother, easier-to-manage hair without committing to permanent straightening.

Why Do People Love Keratin Treatments?

For many clients, it's not necessarily about having perfectly straight hair.

It's about making their everyday routine easier.

Imagine going from spending 30–45 minutes fighting with your hair every morning to being able to dry and style it significantly more easily.

For clients with thick, frizzy or difficult-to-manage hair, that can make an enormous difference.

Keratin smoothing can be particularly beneficial if you experience:

Frizz

Humidity can cause the hair cuticle to react and create that familiar fluffy appearance. Smoothing treatments can make the hair far more manageable.

Long blow-drying times

Thick or coarse hair can take considerable time to dry and style.

Unmanageable volume

Some clients love their natural volume. Others would prefer less of it. Keratin smoothing can help create a sleeker, more controlled result.

Hair that doesn't stay styled

If your beautifully smooth blow-dry quickly turns frizzy, a smoothing treatment may make styling considerably easier.

Why We Use EVY Professional E-Smooth at Chroma Hair & Co

Not all smoothing systems are the same, which is why we're particular about the products we choose to use in our salon.

At Chroma Hair & Co, we use EVY Professional E-Smooth.

EVY describes E-Smooth as a smoothing and semi-permanent straightening system using low-molecular-weight amino acids, organic acids and vegetable proteins, with ingredients including hyaluronic acid, polypeptides and ceramides. The system is designed to smooth and reduce frizz while supporting the condition and manageability of the hair.

For us, choosing a professional smoothing system isn't simply about creating beautifully smooth hair.

We also care about what we're using around our clients and our team every day.

What About Formaldehyde in Keratin Treatments?

This is something we believe clients should be able to ask about openly.

Some hair-smoothing and straightening products can contain formaldehyde or formaldehyde-related ingredients, or release formaldehyde gas during the heating stage of the treatment.

The U.S. Food and Drug Administration warns that formaldehyde exposure can irritate the eyes, nose, throat and lungs. Formaldehyde has also been classified as a human carcinogen by the International Agency for Research on Cancer, with higher or prolonged exposure linked to certain cancers.

This is one of the reasons we're selective about the smoothing system we use at Chroma.

EVY E-Smooth is marketed as a formaldehyde-free smoothing system, rather than relying on traditional formaldehyde-based smoothing chemistry.

For clients considering any smoothing treatment—not just at Chroma—we encourage you to ask your stylist exactly what product is being used.

The FDA similarly recommends asking salons whether their smoothing products contain formaldehyde, formalin or methylene glycol, and whether an ingredient list or Safety Data Sheet is available.

Knowing what's being applied to your hair matters.

Will a Keratin Treatment Make My Hair Completely Straight?

Not necessarily—and this is one of the biggest misconceptions about keratin treatments.

The result depends on:

• Your natural texture

• Hair thickness

• Hair condition

• Previous chemical services

• How resistant your hair is

• Your desired result

Some clients achieve significantly straighter hair.

Others maintain some natural movement but experience dramatically reduced frizz and easier styling.

During your consultation, we'll discuss what you're hoping to achieve and what we realistically expect from your hair.

Can You Have Keratin on Coloured Hair?

In many cases, yes.

Clients frequently have both professional colour and smoothing services as part of their overall hair plan.

However, timing matters.

If you regularly colour, lighten or highlight your hair, your stylist should consider your entire hair history before performing another chemical service.

This is particularly important for blonde hair.

Hair that's already been extensively lightened may require a different approach from healthy, untreated hair.

At Chroma Hair & Co, maintaining the integrity of your hair always comes before chasing a particular result.

Can Blondes Have Keratin Treatments?

Potentially, yes—but blondes require additional consideration.

Lightened hair can be more porous and vulnerable than untreated hair, particularly if it has undergone repeated bleaching.

That's why we assess your hair before recommending a smoothing service.

If your hair isn't in suitable condition, we may recommend improving its condition before proceeding.

Beautiful hair should never come at the expense of healthy hair.

How Long Does a Keratin Treatment Last?

Results vary depending on your hair, lifestyle, washing frequency and home-care routine.

Unlike permanent straightening, smoothing treatments gradually wear away.

How you care for your hair afterwards can make a considerable difference to how long you enjoy your results.

Your stylist will advise you on an appropriate maintenance schedule based on your individual hair.

How Should I Look After My Hair Afterwards?

Your home-care routine matters.

Using unsuitable products can affect both your hair's condition and the longevity of your smoothing treatment.

We generally recommend:

• Professional shampoo and conditioner

• Products recommended for your particular smoothing service

• Regular nourishing treatments

• Heat protection whenever styling

• Avoiding unnecessary excessive heat

• Following your stylist's washing and aftercare instructions

At Chroma Hair & Co, we use and recommend professional haircare from EVY Professional, NAK Hair and Milk_Shake, depending on your individual hair needs.

Rather than recommending the same products to everyone, we'll help you build an aftercare routine based on your hair type, colour and treatment history.

Is Keratin Worth It?

For the right client, absolutely.

The value of a smoothing treatment isn't just how your hair looks when you leave the salon.

It's what happens the next morning—and the morning after that.

If you regularly spend significant amounts of time blow-drying, straightening and controlling frizz, having hair that's easier to manage can completely change your routine.

A keratin smoothing treatment may be particularly worthwhile if:

• Brisbane humidity constantly affects your hair

• You straighten your hair regularly

• Your hair becomes frizzy after blow-drying

• You have thick or difficult-to-manage hair

• You want smoother hair without permanent straightening

• You'd like to reduce your daily styling time

Who Might Not Be Suitable?

Keratin smoothing isn't automatically the right service for everyone.

Your stylist may recommend against—or delay—a smoothing service if your hair is excessively compromised, fragile or otherwise unsuitable for the process.

That's why consultation is important.

Sometimes the best professional advice we can give is not to perform a service yet.

Instead, we may recommend treatments, trims or a longer-term hair plan before reconsidering smoothing.

Keratin Treatment FAQs

Is a keratin treatment permanent?

No. Keratin smoothing treatments are semi-permanent and gradually wear away over time.

Will keratin make my hair completely straight?

Not necessarily. Results depend on your natural texture, hair condition and desired result. Many clients choose keratin primarily for frizz reduction and easier styling rather than completely straight hair.

Does keratin help with frizz?

Yes. Frizz reduction and improved manageability are among the main reasons people choose professional smoothing treatments.

Can I still curl my hair after a keratin treatment?

Generally, yes. A smoothing treatment doesn't necessarily mean you're committed to wearing straight hair every day.

Can I have keratin if my hair is coloured?

Often yes, but your stylist needs to assess your colour history, hair condition and timing of other chemical services first.

Can blonde hair have a keratin treatment?

Potentially. Because lightened hair can be more fragile and porous, we recommend having its condition professionally assessed first.

Does EVY E-Smooth contain formaldehyde?

EVY E-Smooth is marketed as a formaldehyde-free smoothing system. EVY describes its smoothing technology as using amino acids, organic acids and vegetable proteins.
