Dryness has a few different culprits and isn’t caused by just one thing. There are environmental, styling, and genetic factors that could be underneath strands lacking moisture.
Some of the most common causes of dry hair are using shampoo too frequently or the wrong kind of shampoo, over-styling your hair, weather conditions, forced air from heaters (especially during the winter), using heat tools, and having specific genes that run in your family.
Knowing what factors cause dry hair is vital because you can better tailor your solution. For instance, dry hair caused by the constant use of hot tools will need a different approach from dryness that appears in colder months. Take a look at your haircare routine and lifestyle, and consider the time of year. This will help you narrow down the root cause.
