I have Irish/welsh ancestry with curly auburn hair. I live in a humid climate so I'm battling frizz 7/12 months a year. This orchid oil treatment is something I've been using since 2016. This prevents my hair from being "poofy". It doesn't get rid of the frizz straglers on top of my head 100% but I also don't use a whole lot. I just use enough (2 full pumps) to prevent my hair from becoming a poofy web. It also helps keep my hair healthy. If I stop using it for a period of time when my bottle runs out, I can tell my hair is more coarse and tangled when I wash or brush it. I can't tell the oil is in my hair, it's very light and leaves my hair silky. The best way to prevent frizz is combining this with the orchid cream. I just don't use the cream all the time because it leaves a heavier texture on my hair.
