This is my hair rn, only 2 weeks after I cut my dreadz from bottom, I only left 2 or 1.5cms, it's about 4cms now
Swim at least 3x a week at ocean and don't wash your hair at home afterwards, keep the salty water. I guarantee you it works! Wish I took pics when I first cut it! Also when it rains take a shower outside, and Don't shampoo! Water is essential for hair
