Similar to face slugging, hair slugging consists of placing a moisturizing oil in your hair and then positioning your tresses in a sock to protect them while you sleep. The trend has taken off since TikTok user Monique Rapier demonstrated this old practice to a new generation of people with dry hair.

Monique recommends applying a lightweight oil to your hair and then using a fuzzy sock to protect your hair from friction while sleeping. By the way, she makes collecting long hair in a small sock seem like a magical feat. She says she's been doing this practice for a year and has never had shinier, silkier locks. Monique claims this nightly routine also protects hair from split ends and breakage. Her hair does have an immense shine to it and looks like it could be featured in a shampoo commercial, but again this may not be for everyone. If your hair is very oily, certain styling products may worsen the problem, reports Self.

Also, you might want to make sure that you aren't using your best pillowcases when you first try it out, or use a sleeping bonnet. Until you get the hang of tying up the perfect sock-covered ponytail, you might stain your bedding.
