    The paint was an excellent value. Delivery took a while, but that’s not abnormal these days! Item was described as new. Upon receipt, the box was not in the original packing sleeve, it was taped shut with some scotch tape (applied by a consumer), some of which was torn, and the box was a bit damaged. I didn’t contact the seller, so they may have addressed the problem if I did, but, it’s the only time I’ve ever bought a new item that was not new upon receipt (and I’ve made many eBay purchases).

    I can't really rate this item until I use it which may be awhile before I run out of ink and install it. The item arrived quickly in a sealed HP box so the item was as described with an expiration date of Sept 2026. Very good seller.

    Shipping was very fast and the book was well packaged. It was in a plastic bag and then secured in a bubble mailer within a bubble mailer. It was described as near mint condition which I disagree with- the sleeve was torn and the hardback has several dents in it. The rest of the listing and condition is accurate- it has the sprayed edges and is hand signed by the author.

    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.

    This works for me!

    I love the K18 Hair Mask, it really helps with frizz and my curly hair. This was a great value but I have not had a chance to use the product I got from Ebay yet, I am assuming it is new and the same hair mask I've been buying from the retail stores.

    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!
