## Description

K18 Leave-In Molecular Hair Mask, Repairs Dry or Damaged Hair, Reverse Hair Damage from Bleach, Colour, Chemical Services & Heat, 50ml : desertcart.co.uk: Premium Beauty

Review: The best! - Regular heat and bleach is used on my hair and was incredibly damaged. This helped to reverse the damage in 6 weeks and I now use it as maintenance once a week. It is very pricey but definitely worth the money if used correctly. Shampoo, towel dry hair, apply and wait 4 minutes minimum then condition as normal. I also use a hair mask after conditioner and my hair has never felt better.
Review: Great - Really helps damaged or dry hair. Fantastic product

## Questions & Answers

**Q: How does the K18 mask work?**
A: The K18 Mask works as a treatment to reverse damage in 4 minutes. It’s powered by our biomimetic K18PEPTIDE to seamlessly fit in and reconnect broken polypeptide chains at the molecular level.

**Q: What is the K18PEPTIDE?**
A: K18PEPTIDE is a biotech-developed peptide that mimics hair’s structure to reverse damage by reconnecting polypeptide chains and disulfide bonds broken during damage from bleach + colour, chemical services, and heat.

**Q: Why skip conditioner?**
A: Conditioner leaves a film that blocks our peptide from penetrating effectively. Once the 4-minute wait time is up, feel free to use a conditioner, a leave-in, or any type of product.

**Q: I noticed there’s alcohol in the formula, isn’t that bad for you?**
A: We like to keep our formulas minimal, only using the exact amount of ingredients needed to get the peptide where it needs to go. Here the alcohol serves as an agent to optimise the hair environment for the K18 Mask to work on a deeper level.

**Q: When should I expect to see results?**
A: Most see results after 2-3 uses. The more damaged the hair, the more dramatic the results so it may vary depending on your hair type and level of damage.

### ⭐⭐⭐⭐⭐ Great
*by K***E on 10 February 2026*

Really helps damaged or dry hair. Fantastic product

### ⭐⭐⭐⭐⭐ Expensive but worth it
*by B***L on 20 February 2026*

I have used this once and the difference already is significant. My hair was fried after a disaster with a home colour and then colour correction, my ends were crispy and my hair was looking very sorry for itself. I worried about not conditioning my hair but it didn’t matter as the K18 made it feel fabulous, so soft and smooth. Yes it’s expensive but when the only other option it to cut my long hair off it is worth every penny. Hopefully with more use I will see even more improvement. Yes I definitely recommend this.
