Technically yes, we have had plenty of customers bleach their extensions and be very happy with the results, however we strongly do not recommend getting hair extensions bleached, I know Its like a catch 22.
Bleaching is a very harsh and harmful chemical process, It may change the curl pattern and may alter the quality and longevity of your hair extensions, It may also cause excessive dryness that will lead to tangles.
If you decide to go lighter it is recommend you take the extensions to a professional. We would advise you to only dye one small weft prior to coloring the full set to make sure you are satisfied with the resulting shade.
Dying, toning, or bleaching is done at the customer's discretion.
