The Effect of Blue Light on the Scalp and Hair Follicles

Blue light, a component of solar radiation, penetrates the scalp and hair follicles, causing oxidative stress, inflammation, and cell damage, which can lead to hair loss and other scalp issues. The study highlights the biological mechanisms by which blue light affects hair growth cycles and regeneration processes, emphasizing the importance of protective strategies such as antioxidants, filters, and reducing light exposure to mitigate these effects.
