In 1907, Eugène Schulaire, the founder of the brand, invented the world's first non-toxic synthetic hair dye and named it L'Oreal. Today, L'Oréal has grown from a workshop laboratory to a global cosmetics powerhouse. The advantage of L'Oréal Mousse products is that their positioning is relatively high-end, and the quality and safety of big-name products are excellent. However, judging from the feedback from major buyers and major beauty review users, the stereotyped effect of its mousse products is average, the price is also high, and the cost performance is not high.
