Thermosilk: Vegan Keratin Smoothing Treatment for Frizzy Hair

Frizz, excess volume and hair that takes forever to style can make your daily routine harder than it needs to be. Thermosilk Professional Anti-Frizz Treatment is designed to help create smoother, more manageable hair with a professional three-step smoothing system.

Combining vegetable keratin, amino acids, Argan oil, pro-vitamin B5 and Tanino, Thermosilk helps smooth the hair fibre, reduce frizz and control unwanted volume.

The result? Hair that looks smoother, feels softer and can be much easier to manage.

What makes Thermosilk different?

Thermosilk is designed for professionals looking for an effective anti-frizz and hair-smoothing treatment with an ingredient-conscious approach.

The formula is:

• 100% vegan

• Formaldehyde-free

• Paraben-free

• Never tested on animals

Rather than simply focusing on straightening the hair, Thermosilk is designed to reduce frizz and volume while improving manageability, making it a versatile option for clients who want a smoother finish without necessarily wanting completely straight hair.

According to the manufacturer's product information, Thermosilk can reduce frizz by nearly 80% after the first application, with results lasting up to 12 weeks. Individual results will vary depending on hair type, condition and aftercare.

A professional smoothing treatment for different hair types

Thermosilk can be used on hair that has undergone different chemical treatments, making it suitable for a range of clients when the hair is in appropriate condition.

As with any professional smoothing service, the condition of the hair should be assessed beforehand. This is particularly important for bleached, coloured or previously damaged hair.

The recommended flat-iron temperatures are:

• Coloured or damaged hair: 150°C / 300°F

• Blonde hair: 125°C / 250°F

• Natural hair: 180°C / 350°F

Using the correct temperature and professional technique is essential to achieving the best possible result while protecting the integrity of the hair.

What's included in the Thermosilk system?

The complete professional kit contains everything needed for the three-step treatment:

Step 1 – Preparation Cleaner Shampoo | 500ml

The preparation shampoo thoroughly cleanses the hair and prepares it for the smoothing treatment.

Step 2 – Defrizant Keratin Treatment | 1000ml

The main treatment is applied in sections and left to process before being rinsed and followed by the finalising mask.

Step 3 – Finaliser Mask | 500ml

The finaliser helps condition the hair before the treatment is completed with blow-drying and heat activation.

The complete process is designed to leave the hair smoother, more controlled and easier to style.

Is Thermosilk suitable for sensitive clients?

If you're particularly conscious about the ingredients used in your hair treatments, Thermosilk may be an option worth considering.

Its vegan, paraben-free and formaldehyde-free formula makes it appealing to clients who prefer to avoid certain ingredients.

However, it's important not to confuse this with being suitable for everyone with allergies or sensitivities. No cosmetic or hair treatment can be guaranteed allergy-proof.

If you have known allergies, sensitive skin or a history of reactions to hair products, always check the full ingredient list and carry out the appropriate patch test before treatment.

How long do the results last?

Thermosilk results can last up to 12 weeks, although longevity depends on the individual.

Hair type, washing frequency, heat styling, environmental factors and aftercare can all influence how long the smoothing effect remains.

Using suitable professional aftercare can help maintain the condition and appearance of treated hair between services.

What can you expect from a Thermosilk treatment?

Thermosilk is designed to help you achieve:

✨ Less visible frizz
✨ Reduced unwanted volume
✨ Smoother-looking hair
✨ Improved manageability
✨ A shinier, more polished finish
✨ Easier everyday styling

It's a particularly useful option for anyone who enjoys the look of smooth, polished hair but wants to spend less time fighting with frizz and styling.

Professional use only

Thermosilk Professional is for professional use only and should always be applied according to the manufacturer's instructions.

It is not suitable for children or pregnant women.

Hair should be assessed before treatment, and the appropriate precautions and patch testing should be followed, particularly for clients with known sensitivities.
