Care and maintenance for white and gray hair

White and gray hair, in both humans and pets, requires specific care due to a lack of melanin. In pets, the absence of pigment makes the coat and skin more vulnerable to ultraviolet radiation, increasing the risk of sunburn, dermatitis, and skin cancer. Veterinarians recommend hydration and sun protection for animals with light coats, noting that some whitening shampoos may cause dryness.

For humans, gray hair often experiences changes in texture and shine. Home remedies, such as a mixture of honey and coconut oil, can help restore moisture and luster. Additionally, temporary cosmetic solutions like hair retouching sprays from brands such as L’Oréal Paris and Wella are increasingly used to camouflage roots without the need for permanent dyes.
