I just learned about plopping about two weeks ago, but I hadn't found the time to try it. I figured the beach was as good a place as any to go a little bohemian with the hair, and if it looked bad I could always fall back on the puff.
Here are the basic steps -
1. If you like (and I like) you can separate your hair into sections. I've done two (front & back) and four depending on mood.
2. Thoroughly rinse hair with cold water - as cold as you can stand. This can happen after a DC, after a co-wash - whenever.
3. Squeeze a bit of excess water from hair and add product - I go in this order: conditioner, oil, gel. I separate any overly large frizzy feeling clumps into smaller sections, and smooth hair with my hands instead of "combing" my fingers through the length.
4. Once all sections have been rinsed, and product applied, do another quick cold water rinse - just enough to get the texture nice and goopy
From that point on you can follow these instructions:
