5 stars out of a maximum of 5

I never write reviews until now. I had my hair badly bleached recently and the damage was so severe I had to use extensions while trying to recover the rest. I genuinely didn’t expect much, but this product does exactly what it says. I let K18 work on its own for the first four washes, following the instructions carefully. I washed my hair, skipped conditioner, towel dried, and then applied the product. Around the fourth wash I started to see improvement. From the fifth wash, I introduced a homemade pre wash mask to boost the results, and that is when I saw a real transformation. I used aloe vera, honey, and conditioner for about 30 minutes before washing. This helped retain moisture, keep hydration in the hair, and minimise the drying effect of shampoo. This combination with K18 truly brought my hair back to life. I can now say my hair feels saved. The rest will grow back, but this product is now part of my routine for good. Thank you to whoever created it.

I was so lucky to learn about this Product when somebody made a mess of a Colour on my hair. I am a colorist myself, I didnt know about this NEW range. It is K18 and restores the broken ladder that occcur when you do a permanent colour. Hairdressers will know what I'm talking about. What a difference and I never shampoo /blowdry my hair without it. OR ts sister K18 Spray for PRE Colour.
