Keratin Treatment Tutorial



Our product contains amino acids, keratin protein, and wheat protein, which are the best components for restoring and repairing damaged hair. When the hair cuticle absorbs the keratin protein and is sealed by heat, it gives your hair a shiny, glossy look. It also re-energizes hair stems and reduces hair breakage and split ends.

Simply a great, highly effective formula to have healthy, silky, shiny, frizz-free, and beautiful straight hair.

  • Regenerates and repairs damaged hair.
  • 100% free from formaldehyde
  • Naturally straight hair
  • No more frizzy hair
  • No More curly hair
  • Non-toxic and safe
  • No harsh fumes

Before and After

How to use

The Keratin Treatment package contains:

1. Jason Makki Cleansing Shampoo
2. Jason Makki Keratin Protein Treatment
3. Jason Makki Keratin Mask

Step 1: Wash hair 2 times with Purifying Shampoo. Any oils or conditioners left on the hair may affect the effect and penetration of the treatment. Then dry the hair completely with a hair dryer.

Step 2: Apply KERATIN PROTEIN TREATMENT evenly to your hair using a comb and brush. Always start at the nape of the neck, apply the product about half an inch from the roots, and then use a fine-tooth comb to distribute the cream evenly to the ends of the hair (don't apply on the scalp).

Next Step:

  • Remove excess cream with a comb.
  • Leave the cream on the hair for 30 minutes.
  • After 30 minutes, dry the hair completely with a blow dryer.
  • Set the Jason Makki hair straightener to 240°C or 450°F.
  • Starting at the nape of the neck, grasp the sectioned hair with a heat-resistant comb and slowly move the straightener from the roots to the ends, about 8-12 times gently until there is no more smoke. If you do not do this part properly, you will not get a perfect result

Step 3: Apply the KERATIN MASK evenly to the hair and leave it on for 5 minutes. Rinse the hair with water (no shampoo), blow dry, and style as desired. You can rinse the hair without shampoo within 48 hours.

Note: Strongly recommend doing the treatment with a professional stylist or taking the products to a salon and asking them to do it for you. We have done this procedure for more than 5000+ clients. If you are confident doing it at home, make sure the above process is doable for you, and then purchase our products. Transparency is our priority.



Wash your hair with JASON MAKKI Keratin Shampoo and Conditioner for the best results on daily basis.

Apply Jason Makki Keratin MASK for 3-5 minutes on hair strands to deeply nourish your hair, enhance shine and prolong the results of keratin treatment. Apply 2-3 times a week after keratin shampoo.


This product helps to achieve naturally straight hair. Jason Makki Keratin Treatment is suitable for wavy and soft curly hair.

If you have strong curls or afro hair, we recommend repeating the treatment after 1 week. Please note that this product is 100% formaldehyde free, so the formula is less strong, non-aggressive, yet effective and safe. We recommend having this treatment done by a professional ironer or hairdresser for 100% results.

Repeat the keratin treatment every 2 months to maintain the result.

The package comes with an instruction paper for proper use.

There is a 50% chance that white hair gets affected by the heating process and turns slightly yellowish. Also, darker hair color might get one shade lighter and it depends if you have colored your hair or not. Solution for white hair: yellowish color can fade out within 10 washes. If it’s necessary you can apply hair color. It's a common effect due to the heating process, not the keratin product.
