Let's start with the positives. This treatment truly works wonders on my hair. After just a few uses, I noticed a significant improvement in the texture and overall health of my hair. It feels softer, smoother, and looks much healthier. The mask effectively reverses the damage caused by bleach, color, chemical services, and heat, which is exactly what I was looking for.
The application process is simple and convenient. I just apply the mask to my damp hair, It's a quick and easy addition to my hair care routine.
However, I do have to mention that the price of this product is quite high considering the size of the bottle. While I understand that quality comes at a cost, I was a bit disappointed with the amount of product I received for the price I paid. It would be great if the company could adjust the pricing to make it more affordable for regular use.
Despite the price concern, I have to say that the K18 Leave-In Repair Hair Mask Treatment is effective and delivers results. If you're willing to invest in your hair care routine and don't mind the higher price point, this product is worth considering. Just be aware of the bottle size and its impact on the overall value for money.
In conclusion, the K18 Leave-In Repair Hair Mask Treatment is a powerful solution for repairing dry or damaged hair. It works wonders, but the price may be a deterrent for some. If you're willing to splurge a bit, you won't be disappointed with the results.
I was skeptical to not use conditioner at all and only use 3 pumps of this (I usually use conditioner twice), but I am a believer now. My hair hasn’t looked this healthy in months.
I used to apply 3 different leave ins before. Now, I just use 3-4 pumps of K18. It’s really amazing. Just try it.

La primera semana lo usé 3 veces y después solo 2 o 1 a la semana y deja el cabello realmente suave y muy manejable para estilizar.
Había probado el No. 3 de Olaplex, que también es bueno pero definitivamente el K18 es mejor. Lo combino con shampoo de Olaplex.
