1. Hemangioma of the head grows very rapidly, and will grow and expand with the growth of children, gradually invading the surrounding skin and deep tissues, and even causing thrombocytopenia syndrome in severe cases, which is life-threatening.

2. Hemangioma of the head will grow rapidly in the first 6 months, which is very invasive. In a short time, normal body tissues will be seriously damaged, leading to the continuous expansion of eyelids, lips, nose, ears and other tissues. The hemangioma of the baby's head is irregular and purple, which is easy to fester, bleed, infect, necrosis and scar.

3. Hemangiomas in the head are exposed outside the skin, which is easy to cause bleeding, infection and scar. The baby's skin itself is very fragile. Sometimes because the affected area will make the child uncomfortable, it will scratch back and forth, which is easy to cause bleeding in the affected area. Once hemangioma bleeds, it is difficult to stop bleeding, and the wound does not heal for a long time, which is easy to cause infection.

4. Hemangioma of the head can cause occupying lesions, compress nerves, tendons and other tissues and organs, and cause complications such as pain and deformity.
