I didn't have any high expectations for this product since my hair is always frizzy and no product I have purchased and used has ever helped tame my frizzy, dry looking hair, but I figured I would give it a try anyway since it was on sale. I watched Lador's YouTube video on how to use this and they used a milk frother to mix the 1:1 ratio water/fill up. I didn't have one, but figured I could use a mascara/eyebrow brush to use as a whisk. It worked perfectly! I was able to get the mixture to a thick hair mask texture in 15 seconds or so. I left the mixture in my hair for 20 minutes after shampooing and then rinsed it out. My hair immediately felt incredibly soft! My ends looked healthy and shiny! The frizz on the top of my head was significantly reduced. This fill up has given me my best hair yet! I actually had a good hair day/week for once! I intend to continue purchasing this and can't wait to see how my hair improves.
