Hair Straightening Products - Professional Smoothing Systems

Hair straightening products are advanced systems designed for professional salon work. Their purpose is not only to smooth and straighten the hair, but also to improve its overall condition, reduce frizz, minimise excess volume and give the hair a healthier, shinier and more polished appearance.

Modern straightening treatments differ in their technology, active ingredients, smoothing intensity and the type of hair they are designed for. This category includes advanced nanoplasty systems, organic protein straightening treatments, aminoplasty and modern smoothing formulas with a reconstructive and restorative effect.

On this page you will find detailed information about the professional hair straightening lines available at Diana Beauty. This makes it easier to compare their properties, understand the differences between the technologies and choose the right system for the hair type and the desired final result.

What type of hair are professional straightening products designed for

Professional hair straightening products are especially suitable for hair that is:

• frizzy and difficult to style,
• wavy, curly or very tightly curled,
• dry, porous and sensitive to humidity,
• dull and rough to the touch,
• damaged by styling and chemical treatments,
• blonde, bleached or coloured, when it needs both smoothing and colour control,
• thick, resistant and difficult to discipline,
• in need of volume reduction and a long-lasting smooth finish.

How the different hair straightening systems differ

Not every straightening treatment works in the same way. Some systems are based on nanotechnology and organic chemistry, while others rely on proteins, amino acids, organic acids or smoothing and reconstructive complexes. The differences also include the longevity of the result, suitability for blonde hair, the way the formula interacts with colour and the level of nourishment the treatment provides beyond straightening itself.

That is why choosing the right straightening line is just as important as performing the treatment correctly. Blonde and sensitised hair needs a different approach than natural, dark, thick or afro hair. Below you will find a detailed overview of the key professional hair straightening systems available at Diana Beauty.

Bioliss Bioplasty

Bioliss Bioplasty is a premium straightening system created for professionals who expect more than just straight hair. It is designed to improve the quality, porosity and overall appearance of the hair along its full length. This is a hybrid treatment that combines effective straightening with deep hydration, improved smoothness and a visible reduction in frizz.

The advanced Bioliss formula is based on the natural power of organic acids and has been developed in a way that helps preserve the disulfide bonds of the hair while strengthening its structure. This is especially important because after the treatment the hair is not only straighter and softer, but also more resistant to daily stress, friction and humidity.

Bioliss delivers the effect of perfectly smoothed hair regardless of the curl pattern. After the treatment, the hair becomes silky, shiny, more elastic and visibly less prone to frizz. It is a strong option for clients who want a long-lasting, elegant smoothing result without weighing the hair down or creating a stiff artificial finish.

Bioliss performs very well on different hair types, but it is especially interesting for blonde hair. Thanks to its well-balanced pigments and the way the formula works, it can support a cleaner, cooler visual effect on bleached and coloured hair without unnecessarily compromising its condition. Coloured hair may appear visually lighter by several tones, while natural hair keeps its original tone.

Another advantage of this line is that it does not contain formaldehyde, carbocysteine or their derivatives. Bioliss is also a vegan formula. This makes it a very modern salon option that combines strong performance with greater comfort during the service.

Effect and treatment profile: long-lasting straightening, deep hydration, improved porosity, reduced frizz and a very elegant final finish. The result may last up to 8 months. The treatment is thermoactive, so regular blow-drying after washing is important to maintain the effect properly.

NanoBlue Nanoplasty

NanoBlue is a professional nanoplasty line designed primarily for blonde, bleached, toned and colour-sensitive hair. It is a system created for clients who want long-lasting straightening, very strong smoothing and at the same time better control over warm, yellow tones.

The NanoBlue formula is based on nanotechnology and organic chemistry, which allows it to deliver a spectacular smoothing and straightening effect while also supporting the hair structure. A distinctive feature of this line is its blue-violet pigment, which helps neutralise yellow tones in blonde hair and supports a visually cooler final result.

NanoBlue makes it possible to achieve very straight, shiny and visibly less voluminous hair while offering strong anti-frizz control even in humid conditions. This makes it especially valuable when working with blonde hair that becomes difficult to manage, dry and prone to puffiness after bleaching.

This nanoplasty line can act not only as a smoothing treatment, but also as a supportive restorative service because it helps strengthen the hair structure and improve the final appearance of the hair. After the treatment, the hair becomes softer, more organised, more resistant to humidity and easier to style on a daily basis. It is an excellent system for clients who want the long-lasting effect of straight hair together with a more refined and cooler-looking blonde result.

NanoBlue does not contain formaldehyde, carbocysteine or similar substances. It also stands out with a more pleasant scent and a more comfortable salon experience than older, heavier straightening technologies. For weaker or drier hair, supportive preparation such as Pre Nano Botox can be used before the main treatment.

Effect and treatment profile: long-lasting straightening and smoothing with a strong focus on blonde hair and control of yellow tones. The result may last around 10-12 months. This is one of the strongest options for blonde clients who want extremely smooth, shiny and visually cooler-looking hair.

NanoGold Nanoplasty

NanoGold is a professional nanoplasty line designed mainly for natural, darker, coloured, thick, frizzy and difficult-to-straighten hair. It is intended for clients who expect maximum volume reduction, very strong smoothing and a long-lasting straight hair effect.

Like the entire Diana Beauty nanoplasty range, NanoGold is based on nanotechnology and organic chemistry. It works with strong straightening power while also supporting the regeneration of the hair structure. As a result, the hair becomes not only straighter, but also more resistant, smoother and less likely to frizz or lose its shape when exposed to humidity.

NanoGold performs particularly well when the hair is strong, dense, coarse, naturally wavy or curly and needs more decisive control. It is one of the best lines for hair that quickly loses its shape without professional smoothing, becomes puffy and is difficult to keep sleek and polished.

This line gives a very visible smoothing effect, reduces frizz and creates a long-lasting organised result. The hair feels softer, reflects light better and requires less everyday styling effort. It is especially practical for clients who want long-term styling comfort and a strong reduction in volume.

If the hair is dry, porous or weakened, Pre Nano Botox or protective support products can be used before the treatment. This allows NanoGold to be better adapted even to more demanding hair types.

Effect and treatment profile: very strong, long-lasting straightening, volume reduction, smoothing and regeneration for natural, darker and harder-to-manage hair. The result may last around 10-12 months.

Golden Protein

Golden Protein is an organic smoothing and straightening treatment based on a protein formula, designed mainly for natural, darker, coloured and unruly hair that needs smoothing combined with reconstruction. It is a line for clients who want straighter, softer and visibly regenerated hair without heavy or irritating technologies.

The treatment formula is based on safe organic chemistry and includes ingredients such as glyoxylic acid, arginine, proteins, panthenol and coconut oil. This combination makes it possible to straighten the hair while also replenishing structural losses. The treatment does not work only on the surface, but supports a change in the hair fibre alignment while maintaining softness and a healthier-looking finish.

Golden Protein is a very interesting option for clients who want the effect of smooth, straight hair without having to leave the product on the hair for days. One of the major advantages of this line is that the product is rinsed out at the end of the service, so the result is visible the same day and the client enjoys more comfort immediately after leaving the salon.

This line performs very well in reducing frizz, improving shine, smoothing the surface and rebuilding the hair. It is especially suitable when the hair is hard to control but at the same time needs more softness, elasticity and a better feel to the touch. It is a straighter, smoother finish with a more nourishing and reparative character rather than an aggressive one.

The product does not contain formaldehyde, carbocysteine or their derivatives. It does not irritate the eyes or respiratory tract, which makes it more comfortable for everyday salon work. It is a system that balances control over the hairstyle with visible improvement in the hair’s cosmetic quality.

Effect and treatment profile: smoothing, straightening and reconstruction in one procedure. The hair becomes softer, shinier and more regenerated, and the result may last around 5-8 months.

Blue Protein

Blue Protein is the protein treatment variant designed primarily for blonde and bleached hair, especially when the goal is not only straightening but also better control of warm undertones. It is a line that combines smoothing, regeneration and an aesthetic colour-supporting effect to help achieve a cleaner, cooler visual blonde result.

Like Golden Protein, Blue Protein is based on a safe organic formula and works as a straightening treatment while rebuilding the hair at the same time. What makes this line different is the presence of a blue-violet pigment that helps neutralise yellow tones. Because of this, Blue Protein is especially valuable when the client wants to combine smoothness with a better-looking blonde shade.

Blue Protein performs very well on blonde, bleached and more delicate hair types. It helps achieve smooth, straight and shinier hair while delivering a more refined colour result than classic smoothing treatments without pigment support.

For some hair types it is also possible to create a hybrid mixture of Golden Protein and Blue Protein. This can work well on dry hair that needs both smoothing and toning support. At the same time, the amount of Blue Protein should not be too high, because the strong pigment can affect the final shade too intensely.

Blue Protein is designed for blondes that should look not only smooth and healthy, but also cleaner in tone. The treatment offers a high level of working comfort and immediate client satisfaction because, just like Golden Protein, the result is visible right after the service is completed.

Effect and treatment profile: straightening, smoothing, regeneration and support for a cooler-looking blonde effect. The result may last around 5-8 months.

LumiLiss Nanoprotein Treatment

LumiLiss Nanoprotein Treatment is a premium straightening and smoothing line created for clients who expect a luxurious smooth finish, glass-like shine and a visible improvement in the overall condition of the hair. It is a system that combines long-lasting smoothing with a more care-oriented character and a very elegant final effect.

LumiLiss stands out thanks to its formula rich in natural oils and nourishing ingredients such as amla oil, coconut oil, rice oil, jasmine oil and shea butter. This blend helps not only to smooth the hair, but also to improve softness, elasticity, shine and the general quality of the hair along the full length.

This line works especially well for clients who want smooth and glossy hair without making it look heavy or flat. LumiLiss effectively reduces frizz, excess volume and rough hair texture, while still maintaining a softer and more luxurious finish.

It is a very interesting option for hair that needs not only straightening, but also strengthening support. When working on blonde, sensitised or weakened hair, it is especially important to take care of the structure beforehand. That is why, before LumiLiss, it can be worth introducing a preparatory restorative step if the hair is fragile, overly porous or affected by multiple chemical services.

Effect and treatment profile: long-lasting smoothness, reduced frizz and volume, a glass hair effect and a luxurious improvement in the condition of the hair. The result may last around 6-8 months.

Shinique Sleek Elixir - Aminoplasty

Shinique Sleek Elixir is an exclusive aminoplasty created for demanding salons and clients who expect a comprehensive effect from the treatment: visible smoothing, reconstruction, volume reduction and aesthetic colour control. It is a modern premium straightening system designed to create a refined, elegant final finish.

The formula contains an active amino acid complex, Allium Cepa onion extract, cysteine, cysteamine, plant oils and butters. This composition works on several levels: it supports reconstruction of the hair structure, smooths the surface, improves elasticity and helps reduce breakage. For this reason, the treatment is not just a straightening procedure, but a combination of control and strong support for the overall condition of the hair.

Shinique Sleek Elixir also performs very well on blonde hair because it can support colour protection and help neutralise yellow tones. This is an important advantage when working with clients who want straight, shiny hair but do not want to lose the cleaner aesthetic of a cooler blonde shade.

This line offers a very high level of comfort in salon work. The absence of formaldehyde and aggressive fumes makes the service more comfortable for both the stylist and the client. The system can also be personalised, and for more demanding hair it is worth considering a reconstructive support treatment beforehand, for example with Fiber Restore.

Effect and treatment profile: very smooth, shiny, straight hair with reduced volume, improved elasticity and better resistance to breakage. It is an excellent option for clients who want a premium smoothing result without the harsher character of classic straightening systems.

Shinique Keratin Flow

Shinique Keratin Flow is a professional smoothing treatment based on a strongly restorative formula, created for all hair types from natural to bleached. It is a system for frizzy, hard-to-control hair that needs a visible reduction in volume together with an improvement in the appearance of the full length.

Its effect is based on an advanced technology that uses glyoxylic acid, hydrolysed keratin and an exclusive composition of butters and plant oils. Because of this, Keratin Flow does more than smooth the hair. It also supports reconstruction of the hair fibre, improves softness, adds shine and helps create a sleek mirror-like finish.

This is a particularly interesting treatment for clients who are looking for long-lasting smoothing without the heavy, suffocating experience often associated with older straightening technologies. Keratin Flow has been developed to create a very aesthetic final effect without excessively drying out the hair.

The line performs especially well when the hair needs stronger discipline, reduced bulk and a more polished, reflective finish. It is a strong choice for salons that want to work with a product that combines long-lasting smoothing with visible support for the cosmetic quality of the hair.

Effect and treatment profile: long-lasting smoothing, strong volume reduction, shine, a mirror-like finish and an overall improvement in hair quality. It is a very good option for hair that is difficult to control and needs both discipline and reconstruction.

How to choose the right hair straightening system

Choosing the right straightening system depends mainly on the hair type, its current condition, the level of sensitisation, colouring history and the desired final effect. Blonde and bleached hair requires a different approach than natural, thick, tightly curled or highly resistant hair.

• for blonde and bleached hair that needs control of yellow tones, the best options are usually NanoBlue, Blue Protein and Shinique Sleek Elixir,
• for natural, darker, thick and harder-to-manage hair, very good choices include NanoGold, Golden Protein and Shinique Keratin Flow,
• for clients who want a premium result, glass-like shine and a more luxurious finish, it is worth considering LumiLiss or Bioliss,
• for hair that needs straightening combined with stronger regeneration, Golden Protein, Blue Protein, LumiLiss and Shinique Sleek Elixir are especially interesting options,
• for weakened, dry, porous or sensitised hair before the main straightening service, it is worth considering a preparatory or strengthening stage, for example with Pre Nano Botox, Fiber Restore or Pro Complex.

A well-chosen straightening system makes it possible to achieve not only a better smoothing result, but also greater working safety and a more predictable final outcome.

Aftercare after a hair straightening treatment

Proper aftercare after a straightening treatment has a huge impact on how long the result lasts. Even the best-performed treatment will lose quality faster if the hair is washed with aggressive shampoos, exposed to too much heat or left without the right level of hydration and protection.

After the treatment, it is best to use care products matched to the specific line, especially when the manufacturer provides a dedicated home care range. These products help maintain the correct pH balance of the hair, extend the smoothing effect and reduce the risk of quickly washing out the active ingredients responsible for the final result.

In many technologies, regular blow-drying after washing is especially important, particularly when the treatment is thermoactive. It is also worth avoiding strongly cleansing shampoos, aggressive anti-dandruff formulas, random drugstore toners and other products that may weaken or shorten the durability of the straightening result.

A well-planned home care routine means not only longer-lasting straight hair, but also better shine, more softness, less frizz and greater comfort in everyday styling.
