No, hair oil is not inherently bad for your hair when exposed to the sun. In fact, applying hair oil can provide a protective layer that shields your hair from sun damage.
According to experts, using oil on your hair occasionally during the summer can help prevent dryness, brittleness, and dullness caused by the sun's harmful UV rays. Coconut oil is a popular choice for summer use due to its lightweight nature.
However, it is important to note that some hair oils might attract more heat and potentially increase the risk of damage if you're constantly under the sun.
While oiling your hair won't cause dandruff, it's always a good idea to use a hair oil specifically designed for sun protection if you're concerned about damage.
Overall, hair oil can be a beneficial addition to your hair care routine, especially during the summer months.
