I'm 6 years into my loc journey and going through the exact same thing now, lol. It happens, but I did finally buy 3 boxes of black permanent hair dye today, and I'm going to dye mine tonight! 🙌🏾 Your locs turned out beautifully ❤ Also, new subbie!!
Your locs are beautiful and frame your face well. You may consider doing an ACV rinse for the build up . Wash hair with clarifying shampoos and really warm water to dissolve oils .
