If you wear clip-in hair extensions every day, you will encounter one big problem: bald spots! Clip in hair extension wefts are heavier and they will place a lot of weight on your hair, which pull the hair and make it strained over time. Heavy daily usage of clip in hair extensions, especially clip in hair extension sets over 180 grams, will break your hair off! The weight off the clip in wefts is too heavy. They will pull out hair one by one, eventually leaving gaps and bald spots.
