I live in a normally cold state, but the weather here has been mild thus far.
I haven't altered my routine too much. I cut out my glycerine spritz (I felt like it was drying my hair out). I do twistouts on a weekly basis using SM curl milk + a little oil for sealing (usually castor oil and EVOO). I retwist sometime midweek and then cowash on the weekend. Tis all. None too complicated
...but we'll see what happens when the snow finally hits.
