Some people are under the impression that the less they wash their hair, the longer their extensions will last, that’s not true at all. Hair extensions are usually applied with a small bead, so any products containing oil and any excess oil build up will make the extensions slip out. So, it is recommended that you wash your hair more rather than less to avoid oil buildup, especially if you already have naturally oily hair.There is no special prep needed before your shower. At the GVAhair we strictly use 100% human Slavic hair and as long as you are using high quality hair extensions, you should have nothing to worry about.What Products Should I Use?Sulfate-free is absolutely the way to go. These products don’t create as much lather in the shower, but don’t worry because they still get the job done and they maintain the integrity of your extensions. You’ll want to avoid oils, extracts, hydrolyzed silk, wheat protein, or silicone. All of the above will make the extensions slip out. Also your extensions need to be conditioned just like your own hair. Just make sure you are conditioning from mid-length and definitely make sure you don’t apply conditioner on the attachments.
