K18 · Molecular Repair

K18 Molecular Repair Hair Oil 30 ml is a lightweight, silicone-free oil that works on two levels of the hair strand. K18 peptide strengthens damaged hair from within, while natural oils smooth the surface. The result: less frizz and more shine.

What it does for you

• Strengthens damaged hair, which otherwise frizzes more easily.
• Smooths frizz and flyaways without weighing hair down.
• Shine and more vibrant color.
• Heat protection when drying and flat-ironing.
• Leaves no residue, even on fine hair.

How to use it at home

1. On damp, towel-dried hair, apply 1-3 drops from mid-lengths to ends.
2. For the strengthening effect, wait 4 minutes before styling.
3. Dry and style as usual.
4. On dry hair, use 1-3 drops as a finishing touch for flyaways and shine.
5. Add gradually, only if your hair needs it.

For what hair type

For all hair types, especially hair damaged by bleaching, dyeing, or heat, and prone to frizz. Even on fine hair, used in small amounts, it does not weigh it down.

Active ingredients

• K18PEPTIDE: a biotechnologically developed peptide that mimics the structure of hair. It reconnects keratin chains and disulfide bonds broken by bleaching, dyeing, chemical treatments, and heat.
• Avocado and sunflower oils: nourish and smooth the hair strand's surface.
• Squalane and hemisqualane: add shine and tame flyaways without a greasy film.

What else you need

• K18 Molecular Repair Leave-In Mask
• K18 Damage Shield Shampoo
• K18 Damage Shield Conditioner
• K18 Peptide Prep Detox Shampoo

ProBeauty Tip. Apply the oil to the ends first, then use only what remains in your palms on the lengths. The ends are the most damaged and need it the most.

K18 Professional Molecular Repair Hair Mist Spray treatment 150 ml is the lightweight, leave-in spray that starts the K18 salon treatment. It strengthens hair before bleaching, dyeing, or other chemical services. You can also use it on its own as a treatment, together with the K18 mask.

What it does for you

• Hair prepared for bleaching, more resistant to chemical services.
• Strength and elasticity restored at the molecular level.
• Soft, smooth, and moving hair, without being weighed down.
• Works on all hair types, because it works inside the hair shaft.
• Safe on color-treated hair, vegan and cruelty-free.

How to use it at home

1. Wash your hair with a clarifying shampoo, without conditioner.
2. Dry your hair well with a towel and divide it into 4 sections.
3. Spray 6–12 pumps on each section, depending on length and density.
4. Immediately apply a little K18 Molecular Repair mask on top.
5. Wait 4 minutes, without rinsing, then style as usual.

For what hair type

For any hair type, especially bleached, dyed, or chemically treated hair. It has a pH of 7.5-8.0, which opens the cuticle so the peptide can reach the hair shaft. Before bleaching, it is usually applied to barely damp hair and then styled.

Active ingredients

K18 Molecular Repair Hair Mask is a leave-in mask that works at a molecular level on damaged hair. It helps hair affected by bleaching, dyeing, chemical treatments, and heat regain its strength, softness, and elasticity. It is available in a salon-size 150 ml format and a small 15 ml format.

What it does for you

• Repairs the hair from within, where bleaching and heat have broken the bonds.
• Stronger, more elastic hair, even after bleaching.
• Soft, smooth, and moving hair, from the first use.
• Easy detangling, thanks to the cream texture.
• Leave-in: apply, wait, and style.

How to use it at home

2. Dry it thoroughly with a towel.
3. Apply a small amount of mask to the lengths and ends of the hair, starting from the ends and working towards the roots.
4. Leave it on for 4 minutes. Do not rinse.
5. Comb through, add styling products, and style as usual.

For what hair type

For all hair types, especially bleached, dyed, permed, or frequently heat-styled hair. If you use many products, wash first with a clarifying shampoo. It has a pH of 5.0-6.0 and is safe for dyed hair.

Active ingredients
