it can be dye or bleach it ?
yes ,the hair can be colored under #30 very well. As a general rule it is easier to darken the hair than to lighter we recommend to dye darker, not lighter since the hair extension has been natural black, it is difficult to fade the original color. Improper dying will ruin the hair[Smile]We highly recommend having your hair dresser dye the extensions as you will get the results you want, coloring them yourself always poses a high risk of not coming out the shade you want . If you can’t get to a salon, always use a good quality hair dye and test a small sample first[Smile]Usually we don't suggest you bleached the hair,
