Whether you are dyeing your hair or adding some curls with a curling iron, either process can leave your tresses looking dull. Why does this happen? In a nutshell, chemicals as well as heat styling sucks the internal moisture from hair strands, thus making it brittle and fragile.
Not exactly the look most of us are going for; so then, we need to use products that will help combat these issues. To avoid breakage (an enemy to hair growth), it is best to look for heat-shielding and hydrating products that contain silicone. Silicone coats the hair and helps seal in moisture.
