What Are the Signs of Hair Loss?
The signs of hair loss include:
In men, thinning hair on the scalp, a receding hairline, or a horseshoe-shaped pattern that leaves the crown of the head exposed.
In women, thinning of hair in general, but mainly at the crown; complete balding is rare.
In children or young adults, sudden loss of patches of hair; known as alopecia areata.
Complete loss of all hair on the body; a rare disease called alopecia universalis.
Especially in children, patches of broken hairs and incomplete hair loss, usually on the scalp but sometimes involving the eyebrows; the child is most likely rubbing or pulling out hair, a condition called trichotillomania.
Excessive shedding of hair, but not complete baldness, after various illnesses and drug treatments, rapid weight loss, anemia, stress, or pregnancy; a condition known as telogen effluvium.
