i love this product so much, it was so useful for my hair

I wasn't able to see any results after using the product.

This has saved my bleached, dry and brittle hair..saw a difference after a couple of uses..

Have just finished the 15ml size having bought it in November. Will definitely continue to purchase! It leave hair feeling soft and silky and overall more manageable particularly after the 3rd or so use.  Initially I was most concerned about not using conditioner with it as I have quite knotty hair, however having to brush hair out before using it wasn’t a problem after the second use!

I love that I can skip conditioner and use this on wet hair. It leaves my hair very soft and healthy looking. I used this in my husbands hair and it makes a huge difference in his dry brittle and curly hair.

It's no miracle worker, but I honestly understand the hype. The only hair product I honestly feel did repairing to my hair and I've gotten compliments on my hair after using. Strongly recommend for damaged hair or as prevention for hair that is colored or styled often.

The title said it all. Used olaplex 3 before but this treatment changed my hair. I have severely bleached hair and do heat styling every other day and my hair is still soft and smooth even I've gone into maintenance time frame now (once every 3-4 washes not once a week) The only downfall is that it can make an oily scalp oilier on treatment days

Way better than Olaplex. Noticed instant changes in hair, could not stop touching the healthy feeling hair. Price is a downside though

As someone who purchased this hair mask with high hopes, I was sorely disappointed with the results. Not only did it not work as expected, but it also had a negative impact on my hair's manageability. The day after using the mask, I found that my hair was difficult to control and I had to wash it even though I usually only wash my hair every three days. This was frustrating and inconvenient, to say the least. To make matters worse, I later discovered that this hair mask contains professional cleaning components that can penetrate the skin, making it potentially dangerous to use. This was concerning and left me feeling uneasy about using the product again in the future. Overall, I cannot recommend this hair mask due to its disappointing results and potentially harmful ingredients. If you're in the market for a hair mask, I would suggest looking elsewhere for a safer and more effective option.

I have thin fine hair, not bleached but with a little bit of a heat damage. K18 really works on my hair, it makes my hair looks thicker and more healthy. You can see best results after 2-3rd use.
