After using SMOOTH.AGAIN.RINSE for two weeks, my thick hair feels much smoother and less frizzy. The Monoi Oil gives it a soft, shiny finish without weighing it down. I notice less tugging when styling and my hair holds its shape better.

It works well for my coarse hair. The keratin helps repair split ends and makes the strands more manageable. I still need to detangle carefully, but daily use has made a noticeable difference.
