What are the ingredients? Is there Argan oil in it?

I have no idea what the other post is about. The ingredients are posted here already but they are as follows:Perilla Seed Oil, Rosehip Oil, Saw Palmetto Oil, Argan Oil, Copaiba Oil, Rosemary Essential Oil, Peppermint Essential Oil, Vitamin E (d-alpha tocopherol), Lemon Eucalyptus Essential Oil, Lemongrass Essential Oil, Provitamin B-5 (d-panthenol), Carrot Seed Essential Oil, Clove Bud Essential Oil, Candelilla Wax, Vitamin A (retinyl palmitate), Nutmeg Essential OilIt is a pretty incredible list of ingredients actually.

Why is everyone reviewing a shampoo, when this is about a leave-in serum. Isn't it?

You’re right, it is a leave-in serum. A bit oily to my taste, but quite efficient

These reviews are so crazy, the picture advertises a serum, but everyone is reviewing a shampoo. go figure.

Must be different things. I have the shampoo; been using it for about 4 years. Really like it. The shampoo is green, and is not a serum. Not sure what you are seeing. Reminds me, I need to order more! Thanks!
