In 1927, during the Showa period in Japan, the Oshima Tsubaki Group was born in Izu Island and is known for specializing in the production and sale of camellia oil and its products. Tsubaki Oshima Co., Ltd. has a registered capital of 180 million yen and a dedicated oil refinery. The brand's hair oil is a well-established product with a high reputation in the industry, and its formula is pure vegetable oil instead of synthetic silane, which is good and safe for hair nourishment. It should be noted that vegetable oils are more oily, so fine and soft hair should be used with caution, and the dosage must be controlled to prevent excessive use and counterproductiveness.
