The invention discloses high-transparency cationic guar gum and a preparation method and application thereof.The preparation method comprises the steps that 100-200 parts of guar gum is added into 300-500 parts of organic solvent, then 10-30 parts of strong alkaline matter is added, the temperature is increased to 60-85 DEG C, and a reaction is conducted for 2-4 hours; after the reaction is finished, adding 60-80 parts of alkylene oxide, and reacting for 3-4 hours at the reaction temperature of 65-70 DEG C; after the reaction is finished, reducing the reaction temperature to 45-50 DEG C, adding 50-80 parts of a cationic etherifying agent, and reacting for 1 hour; and after the reaction is finished, reducing the reaction temperature to 30-40 DEG C, neutralizing with organic acid, carrying out suction filtration, and washing and drying a filter cake to obtain the high-transparency cationic guar gum. The transparent shampoo has the advantages of being high in light transmittance and low in viscosity, the cation
