How often do I wash my clip in Extensions? By Hair Extension AngelsOctober 25, 20160 Back to Home If you happen to wear Clip in Extensions often. At least three times per week. Hair Extension Angels recommend to wash them at least twice per month, or if you see that they are getting little dull or loosing their softness definitely give your extensions a wash with luscious Mon Platin products and Nywele shampoo and conditioner. These products are infused with luxurious Argan oil that will keep hair hydrated and taken care of, so you can wear it for a long time. Back to Home
