K18 Airwash is the best invention ever
K18 Airwash is the best invention ever. I have really thick long hair and used to have to wash it 4 times a week and now I only wash it twice a week cause Airwash keeps it looking and feeling fresh 🤩 honestly life changing, buy it!

Problem rectified
My order did not arrive to me and was delivered to the wrong address. Once I contacted K18hair.ie, they quickly remedied the situation and I received my shipment within days. The fault had been on the part of the Courier and not K18hair.ie

Excellent products
Excellent products. I got the shampoo, conditioner, leave in mask, molecular hair repair kit. These are not cheap. However only a tiny amount is needed. They work really well.

I absolutely adore this brand
I absolutely adore this brand. I have blonde highlighted hair and it has never been in such good condition as it has been since I started K18, even my hairdresser has commented on the great condition of my hair. I've been using their shampoo, conditioner, hair oil and leave in mask for over a year now, total game changer. Also fastest delivery.
