Olaplex vs Keratin: What’s Right for Your Hair? | Wembley

Olaplex and Brazilian keratin are both professional hair treatments, but they are designed to address different problems.

Olaplex is primarily a bond-building, repair-focused treatment for hair affected by chemical, thermal or mechanical stress. Brazilian keratin is primarily a smoothing treatment used to reduce frizz and make the hair easier to manage.

The simplest way to choose between them is therefore:

If your main concern is damage, think repair. If your main concern is frizz and manageability, think smoothing.

At Glowing Touch Hair Salon in Wembley, Olaplex / Repair Treatment, deep-conditioning treatments and Brazilian keratin are available from 424 High Road, Wembley, HA9 6AH.

Olaplex vs Keratin: What’s the Main Difference?

The two treatments should not be treated as interchangeable.

Neither treatment is automatically better.

The correct choice depends on what you actually want to improve.

What Is Olaplex?

Olaplex is a professional bond-building hair-care system commonly used for hair that has been exposed to bleaching, colouring, heat or other forms of stress.

Olaplex describes its technology as targeting damaged disulfide bonds within the hair structure. You can read more about the brand’s bond-building technology on the official Olaplex website.

In practical salon terms, Olaplex or another repair-focused treatment may be discussed when hair has experienced:

• repeated highlights;
• balayage;
• bleaching;
• colour correction;
• permanent colour;
• frequent heat styling;
• visible breakage;
• or general over-processing.

The important distinction is that Olaplex is not primarily a straightening treatment.

It is chosen because of hair condition rather than because someone wants naturally wavy or curly hair to become straight.

What Is Brazilian Keratin?

Brazilian keratin is a professional smoothing treatment.

Its main purpose is generally to make hair:

• smoother;
• less frizzy;
• easier to blow-dry;
• easier to manage;
• and often straighter-looking.

The amount of texture reduction varies according to:

• the product used;
• hair type;
• application method;
• heat;
• and the client’s starting texture.

A keratin treatment should therefore not automatically be described as permanent straightening.

Some clients may retain substantial movement while finding that the hair becomes easier to style and less prone to frizz.

How Does Our Wembley Hair Team Decide Between Repair and Smoothing?

At Glowing Touch Wembley, the useful starting point is not:

“Which treatment is better?”

It is:

“What problem are we trying to solve?”

The consultation can be thought about in three parts.

1. Hair Condition

The stylist considers whether the main concern is:

• breakage;
• bleach damage;
• over-processing;
• dryness;
• fragility;
• or previous chemical stress.

If condition is the main issue, a repair-focused treatment may be more relevant.

2. Hair Behaviour

The stylist also looks at whether the main problem is:

• frizz;
• puffiness;
• difficult blow-drying;
• excessive styling time;
• or unwanted texture.

If those are the main concerns and the hair is suitable, a smoothing treatment may be more appropriate.

3. Desired Result

There is a major difference between wanting:

“My hair to feel stronger and less compromised.”

and:

“My hair to look smoother and take less time to style.”

Those are different objectives and should not automatically lead to the same treatment.

Which Is Better for Damaged Hair?

If damage, breakage or heavy chemical processing is the main concern, Olaplex or another repair-focused treatment is generally the more relevant option to discuss.

For example, this may apply to hair affected by:

• repeated bleaching;
• frequent highlights;
• colour correction;
• over-lightening;
• or significant heat styling.

A keratin treatment may make damaged hair appear smoother, but smooth-looking hair and structurally healthy hair are not the same thing.

A sleek finish can temporarily improve appearance and manageability without meaning that all underlying damage has disappeared.

Which Is Better for Frizzy Hair?

If the main problem is frizz, puffiness or difficult styling, Brazilian keratin may be the more relevant treatment.

A smoothing service may help some clients reduce:

• frizz;
• styling time;
• reliance on straighteners;
• excessive blow-drying;
• and difficulty creating a polished finish.

But condition still comes first.

Hair that is severely compromised should be assessed before an additional chemical and heat-based service is planned.

“My Hair Is Bleached and Frizzy” — Which Should I Choose?

This is where the decision becomes more nuanced.

Hair can be damaged and frizzy at the same time

.

In that situation, the stylist needs to assess condition before treating frizz as the only problem.

If the hair is highly fragile, breaking or over-processed, the priority may be:

• repair-focused care;
• conditioning;
• reducing further chemical stress;
• or delaying a smoothing service.

If the hair remains suitable for smoothing, the stylist can then discuss whether keratin fits the client’s goals.

The treatment decision should follow the condition of the hair rather than simply choosing the service that promises the sleekest result.

“My Hair Isn’t Damaged but Takes Forever to Straighten”

This is a different problem.

If the hair is in suitable condition but the main issue is:

• frizz;
• puffiness;
• styling time;
• or difficulty achieving a smooth finish,

a Brazilian keratin treatment may be more aligned with the desired result than a bond-repair treatment.

Olaplex is not primarily designed to make naturally textured hair behave like chemically smoothed hair.

“My Hair Feels Dry After Highlights but I Don’t Want It Straighter”

In this case, smoothing may not be the goal at all.

A repair-focused or conditioning treatment may be more relevant if you want to improve how the hair feels while retaining its natural wave, curl or movement.

This is a good example of why “keratin makes hair look healthy” is not enough reason to choose it.

The treatment should match the outcome you actually want.

What Olaplex Cannot Do

Olaplex can be useful within a repair-focused hair-care plan, but it should not be treated as a universal fix.

Olaplex does not:

• permanently straighten hair;
• turn curly hair into straight hair;
• make severely split ends physically rejoin;
• erase every effect of heavy over-processing instantly;
• make unlimited future bleaching risk-free;
• or replace cutting where damaged ends need removing.

It is also not identical to a deep-conditioning mask.

Repair-focused care and conditioning can complement one another, but they address different aspects of how the hair feels and behaves.

What Keratin Cannot Do

Brazilian keratin also has limitations.

A smoothing treatment does not:

• permanently change natural texture;
• guarantee completely straight hair;
• reverse every form of chemical damage;
• make fragile hair automatically safe for further processing;
• or remove the need for ongoing hair care.

The result also depends on the exact product used.

Two treatments both marketed as “keratin” do not necessarily have identical formulas or produce identical results.

Does Olaplex Straighten Hair?

No.

Olaplex is not designed primarily to straighten naturally curly, wavy or textured hair.

The hair may feel smoother or easier to manage after a repair-focused treatment, but this is not the same as deliberately reducing natural texture.

If your main objective is a straighter or significantly smoother finish, tell your stylist clearly.

That will help distinguish a repair goal from a smoothing goal.

Does Keratin Repair Damaged Hair?

Keratin smoothing can make hair feel smoother and appear shinier, but visual smoothness should not automatically be interpreted as complete structural repair.

If your hair is damaged following bleach, repeated colouring or heavy processing, condition should be assessed separately from frizz.

In some cases, repairing and conditioning the hair may be more important than immediately smoothing it.

Olaplex vs Deep Conditioning: What’s the Difference?

These services are also not identical.

A simple way to understand the Wembley treatment menu is:

Olaplex / Repair Treatment

Focused on bond-building and repair support for compromised hair.

Deep Conditioning Mask

Focused on conditioning, softness and improving the feel of dry hair.

Brazilian Keratin

Focused mainly on smoothing, frizz reduction and manageability.

Someone with chemically processed hair may discuss repair.

Someone with dry-feeling but otherwise healthy hair may discuss conditioning.

Someone whose main concern is frizz and difficult styling may discuss smoothing.

The correct treatment depends on the actual problem.

Can You Have Olaplex After Highlights or Bleaching?

Repair-focused treatments are commonly discussed with clients whose hair has been chemically lightened.

Glowing Touch Wembley offers Olaplex / Repair Treatment alongside:

• balayage;
• full-head highlights;
• half-head highlights;
• full-head colour;
• and colour correction.

The amount of support your hair needs depends on its existing condition and how much chemical processing it has undergone.

Olaplex should not be treated as permission to over-process hair, but it may form part of a wider colour and hair-care plan.

Can Coloured Hair Have Keratin?

Potentially.

But tell your stylist about previous:

• bleach;
• highlights;
• balayage;
• permanent colour;
• colour correction;
• previous keratin treatments;
• and significant breakage.

A client with healthy coloured hair and a client with heavily compromised bleached hair should not automatically receive the same smoothing plan.

For more detailed information about keratin on chemically treated hair, read our Wembley keratin treatment guide.

Can You Have Olaplex and Keratin?

Potentially, but having two different concerns does not mean both services should automatically be performed together.

A stylist needs to consider:

• hair condition;
• previous colour;
• previous keratin;
• the smoothing product being used;
• desired result;
• and whether the hair can tolerate the planned services.

The correct sequence can vary.

Rather than independently booking both because one says “repair” and one says “smoothing”, explain what you dislike about your hair and what result you want.

That gives the stylist much more useful information.

Is Brazilian Keratin Suitable for Every Client?

No treatment is automatically appropriate for every client.

The exact smoothing product matters, particularly because formulations can differ.

UK product-safety authorities recalled a professional keratin hair treatment in March 2026 after it was found to contain formaldehyde, a substance prohibited for that cosmetic use. You can read the UK Government product recall notice.

This does not mean every professional keratin treatment contains the same ingredients.

It does mean clients should know what product is being used.

Useful questions include:

• What smoothing product will you use?
• Is it suitable for my hair condition?
• What result should I expect?
• How much heat is involved?
• What aftercare is required?

Our dedicated keratin treatment guide covers this topic in more detail.

Olaplex vs Keratin After Balayage

If you have recently had balayage, first identify what has changed about the hair.

Hair Feels Weaker or More Compromised

A repair-focused treatment may be more relevant.

Hair Is Healthy but Frizz Is the Main Problem

A smoothing treatment may be worth discussing.

Hair Is Both Bleached and Frizzy

The condition needs to be assessed before deciding whether additional smoothing treatment is appropriate.

Glowing Touch already has a separate guide explaining balayage vs keratin treatment in Wembley if your question is whether you need a colour service or a smoothing service.

Does Olaplex Need Repeating?

There is no single schedule that suits every client.

Whether a repair-focused treatment is repeated depends on:

• existing condition;
• how often the hair is coloured;
• bleaching;
• heat styling;
• mechanical stress;
• home care;
• and your stylist’s assessment.

Hair that continues to undergo significant chemical processing may require more ongoing support than untreated hair.

The treatment plan should therefore respond to what is happening to the hair rather than follow an arbitrary fixed timetable.

How Long Does Keratin Last?

Brazilian keratin is temporary.

How long the smoothing effect lasts can vary with:

• the product used;
• hair type;
• washing frequency;
• aftercare;
• styling;
• and subsequent chemical treatments.

Because this subject is already covered in detail elsewhere on the site, see our Wembley keratin guide for further information.
