[Problem] To provide a gel-type composition for hair which easily crumbles, gives a fresh feeling to hands and is highly compatible with hair. [Solution] A gel-type composition for hair comprising an anionic polymer (A), a cationic polymer (B) and water (C), wherein: the content of the anionic polymer (A) is controlled to from 0.2 mass% inclusive to 1.0 mass% exclusive relative to 100 mass% of the gel-type composition for hair； when the anionic polymer (A) alone is dissolved or dispersed in water (C) and then the obtained solution or dispersion is neutralized, the viscosity is 1550-170000 mPa.s inclusive； the ratio of the cationic polymer (B) to the anionic polymer (A) is controlled to 0.17-1.80 inclusive: the viscosity of the gel-type composition for hair is 1.0-8.0 times exclusive as high as the viscosity of the solution or dispersion obtained by dissolving or dispersing the anionic polymer (A) alone in water (C) followed by neutralization； and the pH value thereof at 25°C is 5.50-8.20 inclusive.
