The Science behind Hair Type
Genes are not the only thing that contribute to your type of hair. Your environment can also have a big impact on your hair. With humid weather your hair can get frizzy or curly, while cold winter air can make your hair dry and static-prone.
Your hair also changes as you get older, it becomes thinner and finer. As you age your hair gets drier because the oil glands in your scalp start to shrink.
The way you treat your hair and style can also cause a change in its texture. Bleaching, straightening, and coloring your hair can make it more dry and brittle. Also relaxing your hair can get rid of waves and curls. Perms can do the opposite and give you curls. The hair cream you use also influences your hair texture.
