    Parece funcionar, solo lo he usado 2 veces, debido a que lavo mi cabello 3 veces por semana. Leí los reviews y vi videos para ver como se usa exactamente, mi cabello no es muy largo así que use 5 y no 3 como aconseja el instructivo. Se ve menos seco y más brilloso. Realmente no tengo problemas graves con mi cabello pero 5 días de 7 debo traerlo recogido por eso compre el producto.

    Let me tell you…I was a bit thrown off at the size (I got the $30 one) but this thing has lasted me over a month with every other day use and I’ve been doing 2-3 sometimes 4 pumps per use. It has saved my damaged hair big time. I had burnt up hair sticking all over the place and this stuff has made my hair so soft and healthy feeling. I’ll definitely be repurchasing!

    Love Love Love K18 Leave in repair hair mask.
    My hairdresser introduced this to me and gave me a home sample to try, the results were magical/
    My blonde highlighted hair is back to being soft, shiny and no more fly aways, the ends of my hair are like they have been renewed.
    This product is meant to be used for 4-6 washes after highlights but I love it so much I use it now instead of conditioner, washing my hair every 3 days, it’s so much more economical too.
    Give it a try, you will not be disappointed.

    Everyone, including my hairdresser, kept telling me how great the K18 products are but I never wanted to spend the money and actually just go get it. Finally I caved after needing to blow out my hair more and getting it balayaged. I have naturally curly hair that is very frizzy but when I tell you this product made my hair SO soft and frizz free I mean it! I’ve been searching for salon blowout at home for years without any success. This product has finally given me that! Additionally, I’ve used it when I have my curly hair days and my curls so so soft, bouncy, and vibrant. Can’t emphasis enough how great this is!!!! Absolutely worth the money. You only need a few pumps anyway.

    One $30 for what seems like such a small amount is ridiculous. Does the product work? I guess so but since it’s out of my price range lol I couldn’t give a full month review on it . It’s so little . Like come on now !!! Would I buy again no cause I want my moneys worth lol will be looking into a dupe of this product . Because it’s just too expensive for what seems like not a months worth of product .

    I’ve done one treatment so far and as small as it may be. I can see a difference already. It feels different. Moves different etc. I have curly hair and severely over processed my hair out of ignorance and impatience lmao. Curly hair can take years to “heal” vs straight or wavy hair. I’ve tried sooooo many things. Including olaplex. What olaplex doesn’t tell you is not everyone can use their product. It may be too heavy for certain hair types. And it really didn’t work that well. One time with k-18 and I’m already noticing a difference. It’s expensive for the size but a little goes a very long way.

    Always hesitant to buy beauty products online, but let me just say… the hype for the K18 hair mask is very deserved.

    I have very fine, straight, long & dense hair. I have also been subjecting it to a lot of bleach as of recently & so for the first time in my life I’ve started to have to worry about my hair health. I’ve seen a lot of influencers promote this so I figured I would try it, & even after 1-2 uses I was so impressed. I would suggest using it consecutively for 4-5 showers to see maximum results, and then just as needed afterwards.

    This teeny bottle has been lasting me SO long, but only if you know how to use it properly. You apply this AFTER showering, on damp hair, after only shampooing (no conditioner or masks in the shower). I was worried my hair would be completely unmanageable without condition, but this product is also an amazing detangler.

    Then I split my hair in 4 sections (2 layers on top and 2 on bottom) because I have a ton of hair. Then for each section you use 1-2 pumps ONLY, and then aggressively rub your hands together until the product becomes opaque white. That’s how you get the most out of it.

    I bought K18 as my hair was really dry brittle and frizzy and I must admit after using this 5 times since purchased on 8th Oct I have noticed that gradually my hair has a lot more strength and body which it has never had before so I’m really impressed so far

    K18 is hands down the best product I have ever used on my hair. There is a salon treatment which is followed by applying this product on towel dried hair after each shampoo at home. You shampoo and you never have to use conditioner again. That also shortens your drying time. I have been stopped on the street and complemented on how amazing my hair looks. I have used it for a little over a year and never before have I been stopped by strangers anout my hair.

    I saw K18 on social media of course. I have very dry, mid length curly hair. I bought the small size and it is quite small for the price, used about 10-12 pumps the first time. It did make my hair somewhat softer and shinier but it only lasts the time that you are using it, It doesn’t work for future softness or just healthier hair in general. I wouldn’t purchase this again.
