You can pin your hair in to a bun and wear a beanie so that they’ll stay in shape and be protected from the element, you can choose to take it off at work, however, I won’t recommend this during hot and humid days for comfort’s sake. I also find that washing your hair in the morning and not completely dry them off, which mean they’re still rather moist will help to keep them look natural as they gradually dry off outside, you can add leave-on hair cream/anti-frizz at the same time too if you have them. Alternatively, you can go to salon and get a straight hair perm so that you don’t have to manually do it anymore everyday, although once the root hair start growing long your original problem will come back again and it’s not cheap to perm hair.
