How Often Should You Wash Hair Extensions
Just like your own hair, human hair extensions will accumulate residue through normal wear. However, you do not need to wash the hair extensions everyday to keep consistent results. The hair should be washed as infrequently as possible or when you notice that the hair appears dull or acquires an odor. If you are wearing the hair all day, every day, you can wash them after 3 to 4 wearings.
