Actually, I tend to just scrub my hair vigorously with shampoo... Since I wash it like this every day, it often gets dry and frizzy. That's why I use a hair treatment occasionally! What kind of treatment do you use? I don't use it every day; I use a treatment once a week. It is the Park Joon Protein LP Fit Treatment. It comes in a huge size, so you can use it at a great value. Just be careful, though, because using the wrong treatment can cause a lot of irritation. You can feel your hair becoming silky and bouncy right after using it.
