    Great value for the large K18. I pay more using my cosmetology license so I don’t know how they do it, but it’s great. Arrived in new condition and on time. Seller ships quickly. 👍

    This is a counterfeit bottle of K18. First thing that tipped me off is consistency and smell is not the same as the previous bottle I bought from my hairdresser at the salon. Additionally, the font is wrong, the hole at the bottom is not on the outside, the K18 on the front of the bottle is skinnier than the font on an authentic bottle. I believe the box is authentic. You can see the difference in size of the logo on the bottle vs the box in attached photos.

    LOVE K18!

    I've tried Olaplex and it did absolutely nothing for my hair. I was really skeptical about K18 because you aren't supposed to use conditioner before applying this. I had to shampoo with a clarifying shampoo AND go without conditioner?! My hair was so tangled after my shower. But I followed directions and literally within seconds of applying k18 my hair felt so much healthier! Impressed beyond words. SO impressed that I bought 3 more bottles because I knew this product will forever be in my arsenal! After ONE use my hair felt silky and soft! Something my hair hasn't been in months since my last balayage. Seriously, if your hair is damaged you NEED this!

  • Must-Try for Bleached Hair

    Use Olaplex since its introduction, this compliments it very nicely. A single pump transforms my unruly hair - soft, frizz-free and gloriously shiny. Used consecutively after chemical services and one a week thereafter. If you use silicone-laiden styling products, use a gentle clarifying shampoo weekly.

  • Genie in a bottle

    It has allowed me to grow my hair out longer. I had not been able to get it past the shoulder length till I started using this and now it is past my bra strap and still growing and healthy. I have honestly never used another product like it that repairs the hair without making it look greasy.

  • K18 is Awesome

    K18 saved my hair after it was ravaged by Covid. I lost almost half of my hair two months after having covid. It was terrible! It was frizzy and knotted. So happy I discovered K18! It is pricey but so worth it. I continue to use it every 3 weeks to keep it healthy. It's a miracle worker for the hair!

  • Hair is strong and soft!

    This product is amazing! Just remember to squirt the product in your palm and continuously RUB PALMS TOGETHER until it forms into a solid white consistency. Then you can apply it to your hair. Never use conditioner in the shower (beforehand) if you are planning to use this product that day.
