BKT Nanoplasty vs Cezanne Keratin Smoothing: What's Right for Your Hair?

If you want smoother, more manageable hair, you may be comparing a keratin treatment with a professional straightening service.

While both options can reduce frizz and make everyday styling easier, they are designed to achieve different results. The right choice depends on how much smoothing or straightening you want, your natural hair texture, its current condition and your usual styling routine.

At D’OR Hairstylists, we offer two professional options:

• BKT nanoplasty for a more pronounced straightening result and longer-lasting smoothing

• Cezanne Express keratin smoothing for frizz control, softer texture and easier styling while retaining some natural movement

What Is BKT Nanoplasty?

BKT is the professional nanoplasty treatment used at D’OR. It is an acid-based smoothing and straightening treatment that works alongside heat styling to reduce frizz, relax curl and create a noticeably smoother, straighter finish.

BKT describes its nanoplasty treatment as semi-permanent, with results generally lasting approximately four to eight months. However, this timeframe is a guide rather than a guarantee.

Your individual result and how long it lasts will depend on factors including:

• Your natural hair texture

• The strength and condition of your hair

• Your colour and chemical treatment history

• The formula selected by your stylist

• Your washing and styling routine

• The professional homecare products you use

What Results Can You Expect From BKT Nanoplasty?

BKT nanoplasty can create a noticeably smoother and straighter result, although the degree of straightening varies between clients.

Your starting texture, hair condition and resistance will all affect the final outcome. Some resistant hair types may require more than one treatment to achieve the desired result.

Although many clients experience a significant reduction in curl and daily styling time, we cannot promise completely straight, wash-and-go hair after the first appointment.

BKT also describes its treatment as cumulative. This means repeated treatments may produce a stronger or longer-lasting straightening effect over time. Because of this, we cannot guarantee that your original curl pattern will return completely.

The treatment may also lighten existing hair colour. Your stylist will discuss this with you during your consultation and recommend the best timing for your colour and nanoplasty appointments.

Who Is BKT Nanoplasty Best Suited To?

BKT nanoplasty may suit you if you would like:

• A more pronounced straightening result

• A significant reduction in frizz and curl

• Smoother, more manageable hair

• Less reliance on daily heat styling

• Results that can last for several months

• A longer-term change to the appearance of your natural texture

A consultation is essential before proceeding. Your stylist will assess your natural texture, hair condition, treatment history and desired finish before explaining what is realistically achievable.

What Is Cezanne Keratin Smoothing?

Cezanne Express is the keratin smoothing treatment used at D’OR. It is designed to reduce frizz, soften the hair’s texture and make everyday styling easier.

Unlike BKT nanoplasty, Cezanne is not primarily chosen to create a significantly straightened finish. It may relax some curl and reduce bulk, but it will not necessarily leave your hair completely straight.

Cezanne can be an excellent option if you like having some natural wave or movement but want your hair to feel softer, smoother and easier to manage.

How Long Does Cezanne Express Last?

Cezanne Express is advertised to last for up to 10 weeks. However, results vary according to your hair type, homecare routine, washing frequency and lifestyle.

The result gradually wears off rather than creating a permanent change to your hair.

Using the professional homecare recommended by your stylist can help support the condition of your hair and maintain your smoother result for longer.

Who Is Cezanne Keratin Smoothing Best Suited To?

Cezanne Express may suit you if you would like:

• Less frizz

• Softer, smoother-looking hair

• Improved manageability

• Faster and easier daily styling

• Reduced bulk

• Some relaxation of your natural curl or wave

• A polished finish that retains natural movement

Does a Keratin Treatment Make Your Hair Completely Straight?

Cezanne keratin smoothing is designed primarily to reduce frizz, soften texture and improve manageability. Although it can relax some curl and make hair appear straighter, it does not guarantee a completely straight finish.

If your main goal is a more significant reduction in curl, BKT nanoplasty may be the more suitable option. However, the result will still vary according to your natural texture, hair condition and resistance.

Can You Have BKT or Cezanne on Coloured Hair?

Coloured, lightened or previously chemically treated hair can respond differently to smoothing and straightening services. Before recommending a treatment, your stylist will consider your hair’s strength, elasticity, condition and complete colour history.

BKT nanoplasty may lighten existing colour, so the timing of your colour appointment will need to be carefully planned.

Are Smoothing and Straightening Treatments Damage-Free?

No professional smoothing or straightening treatment should automatically be described as chemical-free or damage-free.

A smoother appearance does not mean a treatment is suitable for every person or every head of hair. The formula, heat application, current condition of your hair and previous services must all be considered.

This is why your consultation is such an important part of the process. If your hair is not currently suitable for your preferred service, your stylist may recommend an alternative treatment or a plan to improve its condition first.

Does D’OR Offer Permanent Hair Straightening?

D’OR does not offer or promote permanent hair straightening. Instead, we provide BKT nanoplasty and Cezanne Express keratin smoothing. These services allow us to recommend different levels of smoothing and straightening based on your hair, lifestyle and desired finish.

Your Consultation Comes First

Choosing between BKT nanoplasty and Cezanne keratin smoothing should begin with a personalised consultation.

Your D’OR stylist will consider:

• Your natural hair texture

• Your colour and treatment history

• Your hair’s current strength and condition

• The amount of curl or frizz you want to reduce

• Whether you want a straighter finish or to retain natural movement

• Your daily styling routine

• The maintenance and homecare involved

We will then explain which treatment is most suitable, what result you can realistically expect and how to care for your hair afterwards.

Your stylist can also recommend professional homecare products to support your result. If you need help choosing new products or using products you already own, please ask—we are always happy to help.
