This is basically an upside down dutch braid (crossing the outside strand under the middle strand). This is my favorite look during the weekends for running errands.
Here's a few tip to get you started:
1. To get rid of grease and give your pony tail some volume and texture spray on dry shampoo. Go with your favorite brand or I would recommend Klorane Gentle Dry Shampoo with Oat Milk. It's gentle for any hair type.
2. You don't have to use a finishing spray to hold your hair. If you want a light, loose and effortless effect you can leave it as is.
