Yes, hair can become less curly as you age. This is usually caused by a combination of genetics and changes in growth patterns. As adults approach their golden years, you can expect their hair to thin and their natural curls to become less defined. While these changes are usually genetically predetermined, there are a couple of other reasons why they may occur.
For example, poor diet, illness, hormonal changes, and even certain medications can all have an impact on curly hair and how it grows as you age. If you notice any dramatic changes to your hair, curl pattern, or begin to experience sudden and dramatic hair loss, we recommend speaking with your doctor.
