does babies hair fall out with cradle cap
Cradle cap Cradle cap is seborrheic dermatitis that affects infants. It presents on the scalp as greasy patches of scaling,[2] which appear thick, crusty, yellow, white or brown.[3] The affected regions are not usually itchy and do not bother the child.[2] Other affected areas can include the eyelids, ear, around the nose, and in the groin. Hair loss can also occur.[3]
Hair follicle The hair follicle is a dynamic organ found in mammalian skin.[1] It resides in the dermal layer of the skin and is made up of 20 different cell types, each with distinct functions. The hair follicle regulates hair growth via a complex interaction between hormones, neuropeptides and immune cells.[1] This complex interaction induces the hair follicle to produce different types of hair as seen on different parts of the body. For example, terminal hairs grow on the scalp and lanugo hairs are seen covering the bodies of fetuses in utero and in some new born babies.[1] The process of hair growth occurs in distinct sequential stages. The first stage is called anagen and is the active growth phase, catagen is the resting stage, telogen is the regression of the hair follicle phase, exogen is the active shedding of hair phase and lastly kenogen is the phase between the empty hair follicle and the growth of new hair.[1]
