I've found that the best way to stave off a case of the crispies is to invest in one of the cheapest beauty items out there: the disposable plastic shower cap. I originally bought a pack of 20 to use in conjunction with deep treatments, however I more frequently use them to sleep in using the "Baggy Method."
If you haven't heard of baggying before, simply put, it is tucking your hair away under a plastic cap to preserve the moisture as much as possible. The best time to do this in my opinion is overnight when hair is prone to dryness due to cotton pillowcases and scarves, and the friction of rubbing against the fabric. I've found that even when I start with dry hair at night, my hair is damp in the mornings due to condensation (from my body heat). So to take advantage of this, I rub a little olive oil or conditioner over my hair before applying the cap, then tie my silk scarf over the cap. In the morning I just fluff and go!
I've also been practicing filling in my brows. Shapely brows are a great, free accessory for all naturals. Practice makes perfect! Just be sure find a color brow pencil or powder that closely matches your hair color. I'm almost there...thanks to Tdavis for the inspiration :)
