Hair is a protein filament that grows from follicles found in the dermis. Hair is one of the defining characteristics of mammals. The human body, apart from areas of glabrous skin, is covered in follicles which produce thick terminal and fine vellus hair. Most common interest in hair is focused on hair growth, hair types, and hair care, but hair is also an important biomaterial primarily composed of protein, notably alpha-keratin.
Hair removal, also known as epilation or depilation, is the deliberate removal of body hair or head hair.
Cosmetics are composed of mixtures of chemical compounds derived from either natural sources or synthetically created ones. Cosmetics have various purposes. Those designed for personal care and skin care can be used to cleanse or protect the body and skin. Cosmetics designed to enhance or alter one's appearance (makeup) can be used to conceal blemishes, enhance one's natural features, add color to a person's face, or change the appearance of the face entirely to resemble a different person, creature or object. Cosmetics can also be designed to add fragrance to the body.
Hair loss, also known as alopecia or baldness, refers to a loss of hair from part of the head or body. Typically at least the head is involved. The severity of hair loss can vary from a small area to the entire body. Inflammation or scarring is not usually present. Hair loss in some people causes psychological distress.
Waxing is the process of hair removal from the root by using a covering of a sticky substance, such as wax, to adhere to body hair, and then removing this covering and pulling out the hair from the follicle. New hair will not grow back in the previously waxed area for four to six weeks, although some people will start to see regrowth in only a week due to some of their hair being on a different human hair growth cycle. Almost any area of the body can be waxed, including eyebrows, face, pubic hair, legs, arms, back, abdomen, chest, knuckles, and feet. There are many types of waxing suitable for removing unwanted hair.
In human anatomy, and in mammals in general, the mons pubis or pubic mound is a rounded mass of fatty tissue found over the pubic symphysis of the pubic bones.
Facial feminization surgery (FFS) is a set of reconstructive surgical procedures that alter typically male facial features to bring them closer in shape and size to typical female facial features. FFS can include various bony and soft tissue procedures such as brow lift, rhinoplasty, cheek implantation, and lip augmentation.
The hair follicle is an organ found in mammalian skin. 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. 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 the uterus and in some newborn babies. The process of hair growth occurs in distinct sequential stages: anagen is the active growth phase, catagen is the regression of the hair follicle phase, telogen is the resting stage, exogen is the active shedding of hair phase and kenogen is the phase between the empty hair follicle and the growth of new hair.
A unibrow is a single eyebrow created when the two eyebrows meet in the middle above the bridge of the nose. The hair above the bridge of the nose is of the same color and thickness as the eyebrows, such that they converge to form one uninterrupted line of hair.
Threading is a method of hair removal for both men and women originating in India and Central Asia. It has gained popularity in Western countries, especially with a cosmetic application.
An eyelash is one of the hairs that grows at the edges of the top and bottom eyelids, spanning outwards and away from the eyes. The lashes grow in up to six layers on each of the upper and lower eyelids. Eyelashes serve to protect the eye from debris, dust, and small particles, and are highly sensitive to touch, thus providing a warning that an object is near the eye. The eyelid margin from which lashes grow is among the most sensitive parts of the human body, with many nerve endings enveloping the roots of the lashes, giving it sensitivity to very light tactile input even at the tips of the lashes, enabling it to trigger the blink reflex when touched. Eyelashes are also an important component of physical attractiveness, with prominent lashes drawing attention to the eyes.
Hair transplantation is a surgical technique that removes hair follicles from one part of the body, called the 'donor site', to a bald or balding part of the body known as the 'recipient site'. The technique is primarily used to treat male pattern baldness. In this minimally invasive procedure, grafts containing hair follicles that are genetically resistant to balding are transplanted to the bald scalp.
Eye liner or eyeliner is a cosmetic used to define the eyes. It is applied around the contours of the eye(s). It is often used to create various aesthetic effects.
Eyebrow restoration is a surgical procedure to reposition the eyebrow. With advancing age, a common occurrence is descent of the eyebrow, or brow ptosis. A similar condition is eyelid ptosis. Eyebrow repositioning is a commonly performed procedure in cosmetic surgery. The brow is repositioned, optimally, for the wishes of the patient as well as to correct the descent.
Cosmetics in the 1920s were characterized by their use to create a specific look: lips painted in the shape of a Cupid's bow, kohl-rimmed eyes, and bright cheeks brushed with bright red blush.
Plucking or tweezing can mean the process of human hair removal, removing animal hair or a bird's feathers by mechanically pulling the item from the owner's body. In humans, hair removal is done for personal grooming purposes, usually with tweezers. An epilator is a motorised hair plucker. Those under the influence of deliriants or trichotillomania may pluck their own hair out of habit.
Madarosis is a condition that results in the loss of eyelashes, and sometimes eyebrows. The term "madarosis" is derived from the ancient Greek "madaros", meaning "bald". It originally was a disease of only losing eyelashes but it currently is the loss of both eyelashes and eyebrows. Eyebrows and eyelashes are both important in the prevention of bacteria and other foreign objects from entering the eye. A majority of patients with madarosis have leprosy, and it was reported that 76% of patients with varying types of leprosy had madarosis.
Prepubertal hypertrichosis, also known as childhood hypertrichosis, is a cutaneous condition characterized by increased hair growth, found in otherwise healthy infants and children. Prepubertal hypertrichosis is a cosmetic condition and does not affect any other health aspect. Individuals with this condition may suffer with low self esteem and mental health issues due to societal perceptions of what a "normal" appearance should be. The mechanism of prepubertal hypertrichosis is unclear, but causes may include genetics, systemic illnesses, or medications.
A makeup brush is a tool with bristles, used for the application of makeup or face painting. The bristles may be made out of natural or synthetic materials, while the handle is usually made out of plastic or wood. When cosmetics are applied using the appropriate brush, they blend better onto the skin.
Male grooming refers to men paying attention to fashion and enhancing their own appearance. This interest has become increasingly apparent in popular culture.
