I have wihte flakes on my pubic hair is it sry skin or crabs? i have white flakes on my pubic hair it don't itch but my body itches is it just really dry skin?

Human : Human pubic lice or "crabs" are typically very small but can be seen attached to the pubic hair and may have a characteristic bluish-gray color around the area. They skin can become a bit red and itchy and may develop some white flakes. They are spread from sexual contact. I would see a dermatologist so that they can differentiate between crabs and other common conditions that can occur in that area such as eczema, psoriasis, etc.

Pubic lice: Blue spots may show on the skin where the lice have been feeding. Nits (eggs) may noted on the pubic hairs. Lice can cause significant itching.
