This winter, I've been baggying nightly, bunning daily, and consistently moisturizing and sealing. Last winter, I moisturized and sealed daily, but my ends looked and felt a hot mess. For me, I'm going to say that it's a mixture of baggying and bunning...the baggying gives my hair moisture and tucking my ends away keeps them from losing it.
I baggy overnight with Qhemet Amla and Olive Heavy Cream, and in the morning, I take off my baggy, seal with a blend of Vatika Oil and Castor Oil, and bun my hair up. I leave it there until night, which is when I take it down, play with it a little, and then baggy it for the next day. hth.
