There are many signs of hair damage and weakness due to heat exposure that you may not recognize. One of the most obvious signs is when the cuticle of our hair is broken. You can notice your hair losing its natural shine, appearing dry and dull. Also, when the hair becomes dehydrated and lacks moisture and water, split ends will occur. Breakage, frizziness, and even changes in hair texture should also be mentioned. You should be aware of these signs to find an instant solution.
