Provided is a hair cosmetic product, including a first agent having a basic agent and a second agent having an oxidant. The first and second agents are used in a dual-structured container, which contains a structure to separately propel the first and second agents from the container by a propellant at the same time. The dual-structured container has two independently established spaces for filling the first and second agents, and the spaces are in the interior of the space for filling compressed gas of pressurized propellant. The viscosities of the first and second agents are both within the range of from 7000 to 30000 mPa．s at 25℃.本發明揭示一種毛髮用化粧料，其係包含：含有鹼劑之第1劑及含有氧化劑之第2劑。此第1劑及第2劑係於雙重容器中使用者，該雙重容器具備藉由噴射劑將該第1劑及第2劑互相分離、同時吐出之結構。雙重構造容器，係在填充有加壓用噴射劑之壓縮氣體填充空間的內部分別獨立地設置第1劑填充用空間及第2劑填充用空間。第1劑及第2劑皆是以液狀被吐出，第1劑及第2劑的黏度於25℃皆為7000至30000mPa.s之範圍內。
