    How to wash 18 inch clip in hair extensions?

    So you been wearing your hair extensions for a couple weeks and they’re starting to smell a little less than fresh and now it’s time for your first wash so what do you need to do? 

    If you have synthetic hair extensions then we suggest washing or cleansing them after every 15 wears which is roughly once a month.

     Human hair extensions require you to do a little bit more and we suggest you wash them after every five or so wears, which is on average about every fortnight. 

    The process is a little different for each type of 18 inch clip in extensions and we will focus on synthetic hair first.

     Remember we told you that synthetic hair is made from artificial fibers, therefore you don’t need to treat them like natural hair when you wash them. All you really want to do is cleanse them of any extra dirt or debris from while you have been wearing them.

    You can rinse them quickly under warm running water holding the 18 inch clips together and letting the water trickle down the length of the hair. Then using a mild shampoo, smooth this over the hair and then give it a rinse.

     Synthetic hair can get tangled very easily so you don’t want to swish or scrub. If you don't hold it together you end up with a knotted mess that is unusable. 

    You don’t need to use a conditioner or any fancy creams or serums, just make sure all of the dirt and shampoo is rinsed out thoroughly and allowed to air dry flat. Once it is dry, you can then use a large brush or wide tooth comb to gently detangle, as when its wet it becomes very elastic and can snap. 

    Washing human hair 18 inch clip in extensions is really easy and just follows the same steps as you would wash your own hair. You can choose to do it under running water or in a bowl filled with warm soapy water.

     When conditioning the hair extension, try not to get any of the product too close to the roots or where the 18 inch clips are as it can damage the hair and make them greasy in the long run. Aim for a least 2 inches down.

     Where ever possible, always try to deep condition or leave the conditioner to soak in for a least 30 minutes before rinsing.

     You can expect some shedding with these extensions, so always be gentle and detangle with your fingers first to minimise any extra hair loss.

     Dry the 18 inch clip-in extension on a flat towel or smooth surface will work to reduce the possibility of damage when compared to using a blow dryer or other heaterd tools. 

    Just before the hair is completely dry, when it’s still a little bit damp to the touch, you can add a little oil such as Argan or jojoba or a serum to help smooth and coat the strands.

     When the hair is completely dry, you can store them as usual without styling beforehand unless you plan to year the straightaway.
