Changes in Hair Texture
What causes hair to become wavier?
There are several reasons for an individual with straight hair to find their hair has become wavier or even curlier. Causes include age related genetic programming, endocrine disorders (ie hypothyroidism), scarring alopecias, hair trauma (from heat or chemicals), androgenetic alopecia, medications (ie retinoids, minoxidil) and a variety of inflammatory disorders.
