The question was asked – how do I re-freshen up my locs? I do want to say there are some DIY things that you can do like add a little essential oil to water and spritz it on your hair. There can be some problems with that however. Too much essential oil can increase scalp sensitivity if you do not know how to mix the proportions correctly. A quicker fix would be to buy the Sisterlocks Fresh Hair Mist and spritz that on your hair from time to time. They typically have a very light natural enjoyable fragrance. This is also great for dreads or traditional locks.
