@masassippi: Horse oil shampoo is a popular hair care product in Japan, often found in hotels and inns (ryokan) as part of their amenities. It's known for its moisturizing properties, with horse oil being similar to human sebum and easily absorbed by the skin and hair. This makes it effective for moisturizing dry hair and scalp, and it's also believed to help with dandruff and itchy scalps. #japan #japantravel #hotel #shampoo #hotsprings
