Piling on the Moisture - LOC method

Today is the first of too many cold days to come here in Nagoya. I am not a fan of the colder months at all. You see, I'm an island girl hailing from Jamaica - land of sun, wood and water, so the cold is just too much for me. It wreaks havoc on everything from my sinuses to my skin and it doesn't bypass my hair in the process. It leaves both my skin and my hair screaming for moisture!

How do I put back what the cold, dry air takes away from my hair? Typically, I'd moisturize and seal, but this won't cut it in the winter. I've got to pull out the big guns, enter the LOC method of moisturizing.

Layering it on - M & S

Whether relaxed or natural, black (people's) hair is inherently dry! Many of us struggle with this (myself included) and attempt to combat dryness in various ways. We deep condition, steam, co-wash, and use leave-ins on a weekly basis, but there is one vital measure used to keep dryness at bay on the daily! What is it?

Moisturizing and sealing. 

Straight hair - Hair Repair & Jojoba oil
Curly styles - Water, Wave Nouveau & Coconut oil

This is the act of applying water or a water-based product to our strands to provide our hair with much needed moisture and then using a layer of oil on top of our water-based product to ensure that it isn't readily evaporated. 

Why do it?
