Blood supplies hair and skin with essential nutrients, oxygen, and hormones necessary for their growth and health. It delivers vitamins, minerals, and amino acids that support cellular regeneration and repair. Additionally, adequate blood flow helps maintain hydration and overall vitality of the skin and hair follicles. This nourishment is crucial for healthy hair growth and skin appearance.
Lice live off the hair, the skin and blood from your scalp

Albinism is an ABSENCE of skin, eye and hair color. The skin will usually appear pinkish- that is the color of the blood in the fine blood vessels.
Blood vessels in the scalp provide nutrients and oxygen to hair follicles, enabling them to grow. As long as the blood vessels are healthy and continue to supply the required nutrients, the blood stream will feed the hair follicles, supporting their growth. If there are any issues with blood flow or nutrient supply, it can affect the health and growth of the hair follicles.
Hair grows from hair follicles, which are found within the skin of mammals. Each hair follicle is connected to blood vessels and nerves, allowing hair to grow and be nourished with essential nutrients.
When you pull out a hair, you typically don't bleed because hair follicles are not surrounded by blood vessels; they are located in the dermis layer of the skin, which contains the blood supply. The hair itself is made of keratin and is not living tissue, so removing it usually doesn't affect the surrounding skin or cause damage to blood vessels. However, if the hair is pulled out forcefully or if the skin is irritated, it may cause minor bleeding or soreness.
The dermis contains blood vessels that supply skin cells and hair roots with essential nutrients and oxygen. These blood vessels also help remove waste products from cellular metabolism. This nourishment is crucial for maintaining healthy skin and supporting hair growth. Additionally, the blood vessels play a role in regulating body temperature through the dilation and constriction of blood flow.
Ticks feed on their hosts by piercing the skin and slowly sucking blood through the broken tissue. The spiro-chete enters the host as the tick fills itself with blood
