* Palms of the hands: The skin on the palms is specialized for grip and touch.
* Soles of the feet: Similar to the palms, the soles are adapted for walking and sensation.
* Lips: The vermilion border (the red part) of the lips does not have hair follicles.
* Mucous membranes: This includes the inside of the mouth, nostrils, and eyelids.
* Nipples: The nipple itself has no hair follicles. However, the areola (the darker skin around the nipple) may have some hairs.
* Some parts of the genitals: Specifically, the head of the penis and the inside of the vagina.
* Eyelids (the margin of eyelids has eyelashes, but the skin on the eyelid itself does not grow hair)
* Scar tissue: Hair follicles are destroyed in scar tissue.
It's important to note that there can be variations between individuals, and certain medical conditions can cause hair growth in unusual places.
