Causes of Hair Loss
Before delving into how red light therapy can help with hair loss, it is important to understand the different causes of hair loss. Hair loss can be caused by genetics, hormonal changes, medical conditions and treatments, environmental factors, and lifestyle choices. Genetics play a significant role in hair loss, with male and female pattern baldness being the most common type of hair loss caused by genetics. Hormonal changes, such as those that occur during pregnancy, menopause, or thyroid imbalances, can also lead to hair loss. Medical conditions such as alopecia areata, scalp infections, and chemotherapy can also cause hair loss.

Finally, lifestyle choices such as poor nutrition, smoking, and excessive hairstyling can also lead to hair loss.
Red Light Therapy for Hair Loss
Red light therapy for hair loss is a non-invasive treatment that has gained popularity in recent years due to its potential effectiveness in promoting hair growth and improving the overall health of hair.
