Some hair products make hair feel better for a day. K18 is different: it is the leave-in treatment that actually rebuilds the broken keratin chains inside damaged hair, and it does it in four minutes, with no rinsing. If your hair has been through bleach, colour, keratin or protein treatments, chemical straightening or years of heat, this is the repair step stylists across the world reach for first, and now you can order it in Egypt.
Why you will love this K18 hair mask
The formula is a light, silky cream that disappears into towel-dried hair. One or two pumps is all most people need, so even the 15 ml mini lasts for several treatments and the 50 ml bottle keeps you covered for months. Results are visible from the first use: softer, stronger, smoother hair with more bounce, and they keep improving with each application.

- Repairs hair in just 4 minutes, leave-in with no rinse needed
- Restores strength, softness, smoothness and bounce

- Highly concentrated: a little goes a long way
- Immediate results that get even better over time
- Allure Best of Beauty 2022 and Readers’ Choice 2024 award winner
What it does
Hair is held together by keratin chains linked by polypeptide bridges. Bleach, colour, heat and chemical services break those chains, which is why damaged hair feels weak, rough and stretchy. K18’s patented, bioactive K18PEPTIDE™ is small enough to reach the innermost layer of the hair and reconnect those broken chains, restoring the strength and elasticity of the original structure rather than coating the surface. That is why the repair is real, cumulative and not washed away with the next shampoo.
Who it is for
Anyone with damaged, weak or over-processed hair: bleached and highlighted blondes, regular colour clients, hair that has been chemically straightened or protein treated, and anyone who uses a straightener or curling iron most days. It suits every hair type and texture, and it is a favourite in Cairo salons for reviving hair worn down by heat and sun.
How to use it
Shampoo to remove dirt and oil, then skip conditioner so it does not block the K18PEPTIDE™ from reaching the innermost layers. Towel-dry, then apply 1 to 3 pumps of the 50 ml (or 3 to 6 pumps of the 15 ml mini) depending on length and density, starting at the ends and working up towards the roots. Wait 4 minutes, then comb, add your usual products and style as normal. For damaged hair use it during the first 4 to 6 washes, then once a week or as needed to maintain healthy hair.
