🌞 Why Your Hair Needs Sun Protection Too
Most people apply sunscreen to protect their skin from UV rays, but forget that hair and scalp are equally vulnerable. UV radiation can:
- Break down keratin (the building block of hair)
- Fade hair color (natural or dyed)
- Cause dryness, split ends, and frizz
- Lead to scalp burns or even DNA damage
According to a study in the Journal of Photochemistry and Photobiology, prolonged sun exposure leads to protein degradation in hair shafts Source.
“Sunlight causes irreversible changes in hair structure, especially in colored and chemically treated hair,” says Dr. Rebecca Kazin, MD, FAAD.
DIY hair sunscreens made with natural oils, herbal infusions, and antioxidants can offer broad-spectrum UV protection without harmful chemicals like oxybenzone.
