Does this suit me?

It’s best for:

  • Curly, wavy, coarse and frizz prone hair

Professional treatment compatibility

This treatment is designed for professional keratin smoothing protocols. Hair is cleansed twice with JUSTK Keratin Purifying Shampoo, dried completely, treated in small sections and processed for 25 minutes. The treatment is then rinsed with water without shampoo before the hair is blow dried completely and flat ironed.

Flat iron temperature should be selected according to hair condition. The supplied professional guide recommends lower temperatures for severely damaged hair and higher temperatures for hair without damage. Correct assessment, controlled sectioning and even product distribution are important parts of the service.

Frequently asked questions

What results is Justk Ultra Smooth designed to provide?

It focuses on maximum smoothing, curl reduction, frizz control, softness and shine. It is a strong choice when the desired result is straighter, sleeker and easier to manage hair rather than light curl softening.

What makes this treatment different from a basic keratin treatment?

The formula combines Glyoxylic Acid with two keratin ingredients and an extensive conditioning oil blend. Argan, Jojoba, Coconut, Avocado, Sunflower, Grape Seed, Sweet Almond, Wheat Germ, Soybean and Macadamia oils provide broad conditioning support alongside the smoothing system.

Does the treatment need to be rinsed before flat ironing?

Yes. After the 25 minute processing period, rinse the treatment with water without shampooing. Blow dry the hair until completely dry before beginning the flat iron stage.

What temperature should be used when flat ironing?

Temperature depends on hair condition. The supplied guide lists 380°F to 410°F (193°C to 210°C) for severely damaged hair, 410°F (210°C) for medium damage and 450°F (232°C) for hair without damage. A professional should assess the hair before selecting the temperature.

What is the professional tip for an even smoothing result?

Work in small sections and use a fine tooth comb to distribute the treatment evenly while removing excess product. During the sealing stage, keep sections controlled and select heat according to the hair’s condition.

Is Justk Ultra Smooth Maximum Smoothing Keratin Treatment formaldehyde free?

JUSTK identifies the product as formaldehyde free. The supplied ingredient list does contain Glyoxylic Acid, so formaldehyde free should not be interpreted as acid free. This is a professional heat activated smoothing treatment and should be used according to the manufacturer’s salon protocol.

How to use

Steps

  1. Wash the hair twice with JUSTK Keratin Purifying Shampoo to thoroughly cleanse the hair and remove product buildup.
  2. Blow dry the hair until it is 100% dry.
  3. Pour approximately 2–3 oz (60–90ml) of JUSTK Ultra Smooth Maximum Smoothing Keratin Treatment into a non-metallic bowl.
  4. Starting at the nape, work through the hair in small sections. Apply the treatment evenly, then use a fine-tooth comb to distribute the product through each section and remove excess.
  5. Leave the treatment on the hair for 25 minutes.
  6. Rinse the treatment from the hair with water. Do not shampoo.
  7. Blow dry the hair again until it is completely 100% dry.
  8. Divide the hair into small sections. Starting at the nape, use a flat iron to straighten and seal the treatment into the hair.
  9. For ongoing maintenance, use JUSTK Keratin Daily Care Shampoo and Conditioner.

Professional tip

Apply the treatment evenly without oversaturating the hair. Fine, controlled sections during application, blow drying and flat ironing help create a more consistent smoothing result from roots to ends. Always select the flat iron temperature and number of passes according to the hair's condition, texture and chemical history.
