Ultraviolet (UV) radiation is a type of radiation energy that reaches the Earth from the sun and is classified into three types based on their wavelength: UVA, UVB, and UVC. Among the three, UVA and UVB rays penetrate the Earth’s atmosphere and reach our skin and scalp. Although the impacts on the skin are widely understood, they also carry notable consequences for the scalp. 

When the scalp is exposed to UV rays, they can cause DNA damage and oxidative stress in cells, resulting in diminished cellular function. Specifically, UVB rays directly harm DNA, increasing the risk of skin cancer and the breakdown of collagen, thus contributing to the aging of the scalp. Collage is crucial for maintaining the elasticity and strength of the skin, so its breakdown can contribute to issues related to scalp health.

In the short term, scalp damage caused by UV rays can cause dryness and inflammation. However, the effects of long-term exposure are more serious, significantly compromising the health of the scalp, which in turn affects hair growth. Optimal hair growth depends on a conducive scalp environment. However, UV damage impacts the hair follicles and dermal papilla cells, leading to a reduction in hair growth, degradation of hair quality, and eventual hair loss. 

Effective measures to protect the scalp from UV rays include wearing a hat when outdoors and using scalp care products with UV protection like “CRES Senon Scalp Lotion.” By incorporating UV protection into your daily routine, you can maintain healthy hair and a healthy scalp. 

UV exposure poses invisible risks to our scalp. Since scalp health directly correlates to hair beauty, proper UV protection is crucial every day. Let’s protect our scalp and hair health in the long term by implementing preventive measures grounded in scientific knowledge.
