With proper maintenance, links can last from three to five months. That means being mindful of the products you're using, and how often. "With microlinks, it's recommended for you to wash and condition your hair once a week," McKnight said. "Just be sure not to get any conditioner or oils close to the scalp as this can cause link slippage."
McKnight also advises brushing or combing your hair daily for the best results, but be careful to use gentle strokes. "These hair extensions are attached to your real hair and they are clamped on, so you'll want to be gentle when brushing and combing - you do not want to vigorously pull or tug when brushing/combing as this can cause slipping or worse be damaging to your hair."
