Lord Kartikeya takes care of health, family life, healthy children, and assets such as land, etc. 

Those who are suffering with Rahu, Ketu, Kala Sarpa Dosha (In the Vedic chart, people whose planets sit between Rahu and Ketu.), and those having sarpa shap (curse of the snake) should worship Karthikeya.

Karthikeya has six heads and is an embodiment of perfection. He is a war god and brave leader of God’s forces, created to destroy the demons which represent the negative tendencies in all of us. Karthikeya tends to the spiritual growth of aspirants, having the fire and energy to lead the army towards moksha. He represents transmutation of sexual energy and utilizing such energy for spiritual evolution.
