The total time of bonding depends on factors like the adhesive used, your skin type, the climate, and your lifestyle. We recommend you only remove it and get it cleaned every 1-2 weeks to extend the lifespan of the hair system. If you don’t sweat a lot and live in a dry climate, you can leave it on for longer time, about 3-4 weeks.If you attach a lace hair system with liquid adhesive, we don’t recommend you to wear it for more than two weeks in a row. If you wear it for too long time, the adhesive will penetrate through the lace which makes it very difficult to clean.How long you can wear a bonded hair system before removing and cleaning it will depend on the attachment method and adhesive you choose, how your body reacts to the adhesive, and how much hold time you’re hoping to get. Ultimately, each person experiences a different hold time; there are a few different reasons for that. Everybody’s body chemistry is different and breaks down the adhesive differently.The term “body chemistry” refers to variables like scalp oil, perspiration, and hormones. For example, someone with an active lifestyle may have a shorter hold time, because the salts, oils, and bacteria released during perspiration cause the adhesive to break down faster than someone who has a sedentary lifestyle. Similarly, those with oily skin typically need to remove their systems more frequently, because scalp oils break down the bond faster. In general, most people wear their hair systems for a week or two before removing, cleaning, and reattaching.
