Sun and hair loss
Contrary to some popular rumors, the sun does not actually contribute to hair loss. However, it’s always a good idea to protect your hair and scalp against the sun’s harmful UV rays with a hat or scarf, or use UV hair protectant products such as a liquid sunblock. Long term exposure to UV rays may damage your hair, leaving it dry and brittle, and more prone to breakage as well as split ends. So, don’t forget to deep condition your hair on a regular basis.
In order to keep your scalp and hair healthy during the summer, consider limiting your time in the sun or wearing a loose hat in order to protect your scalp. Doing additional conditioning treatments and washing your hair less during the summer may also help to protect the follicles and scalp. Just like the rest of your skin, you want to make sure it is getting enough moisture to stay healthy. Drinking enough water will also ensure your skin is properly hydrated.
While it’s normal to lose up to about 100 hairs a day in the shower and from hair brushing, there may be many possible reasons why your hair is falling out. Some of the most common causes of hair loss include aging, stress, nutritional deficiency (poor diet), medications, and genetic predisposition for hair loss called androgenetic alopecia (male or female pattern hair loss). But most often, hair loss in women is the result of a hormonal imbalance. Child birth, menopause, birth control, and thyroid disorder can trigger hormonal changes, which in turn can cause thinning hair or loss of hair in females.
