Burned hair in fire
I burned a big portion of my hair and I immediately got it soaking wet, towel dried and used an entire bottle of k18 oil and here is what it looks like 2 days later

Perfect post-blowout oil to lock in smoothness and
I absolutely love this hair oil! I always use it right after blow-drying my hair as a finishing touch. It works amazingly well to maintain the smoothness of my ends and ensures that there is absolutely no frizz left behind. It leaves my hair looking super sleek, shiny, and feeling incredibly soft without weighing it down. It’s definitely a premium product that is worth every penny for blowout maintenance!
