Hair exists in a variety of textures. Three main aspects of hair texture are the curl pattern, volume, and consistency. All mammalian hair is composed of keratin, so the make-up of hair follicles is not the source of varying hair patterns. There are a range of theories pertaining to the curl patterns of hair.
The inner root sheath or internal root sheath of the hair follicle is located between the outer root sheath and the hair shaft. [1] It is made of three layers: Henle's layer, Huxley's layer, and the cuticle. [2] The inner root sheaf serves to protect growing hair. [3]
Layered hair: A women's hairstyle where different sections of the hair are cut at different lengths to give the impression of layers. Liberty spikes: Hair that is grown out long and spiked up usually with a gel Lob: A shoulder-length hairstyle for women, much like a long bob, hence the name. Mullet: Hair that is short in front and long in the back.
Layered hair is a hairstyle that gives the illusion of length and volume at the same time, using long hair (in the back) for the illusion of length, and short hair (in the front) for volume, as an easy style to manage. Hair is arranged into layers, with the top layers (those that grow nearer the crown) cut shorter than the layers beneath.
A dense subcutaneous layer of fat and fibrous tissue that lies beneath the skin, containing the nerves and vessels of the scalp. A: Aponeurosis. The epicranial aponeurosis or galea aponeurotica is a tough layer of dense fibrous tissue which anchors the above layers in place. It runs from the frontalis muscle anteriorly to the occipitalis ...
Anatomy of hair Diagram of the hair shaft, indicating medulla (innermost), cortex, and cuticle (exterior.) The medulla is the innermost layer of the hair shaft. This nearly invisible layer is the most soft and fragile, and serves as the pith or marrow of the hair. Some mammals don't have a medulla in their hair. The presence or absence of this ...
The hair follicle is an 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]
Guard hair or overhair is the outer layer of hair of most mammals, which overlay the fur. Guard hairs are long and coarse and protect the rest of the pelage (fur) from abrasion and frequently from moisture. They are visible on the surface of the fur and usually lend a characteristic contour and colour pattern.
