Yes you can color halo extensions. Because our hair is 100% human hair all collections can be dyed. Just note that you should only use semi or demi permanent hair dye. You should never ever lift the color, only deposit it. You want to keep the hair healthy. Color darker, never lighter. For best results we recommend salon assistance by a professional familiar with coloring extension hair. We always recommend to first dye a test strand to see how the hair takes to the color before proceeding to dye the complete set of hair. It is not recommended to drastically change the color as extension hair is double processed already. Processes such as coloring, straighten, waving and bleaching.
When working with dark colors it is not advised to bleach or lighten them. It is best to start with a lighter color you desire and add darker pieces or sections to match your hair. Seek an experienced professional for best results as they have access to professional grade color systems. Allowing you to keep the hair healthy in the process as many on the shelf coloring systems have harsh chemicals.
