The Benefits of Color-Treated Hair


The Benefits of Color-Treated Hair

The human hair is a nonliving fiber that grows from follicles, tube-like sacs on the skin and scalp. It is a collection of keratinized protein. As hair ages, the cells mature, losing their nucleus, and emerge from the scalp. A person’s natural color and texture depend on her genetics and lifestyle. However, her hair can still be colored as she likes. Here are some of the benefits of color-treated hair.

The earliest evidence of hair on humans can be traced to the common ancestor of mammals (synapsids). Fossils of synapsids rarely show soft tissues, and fossils of the basal synapsid stock bear transverse rows of rectangular scutes similar to those of modern crocodiles. This means that the age at which hair developed could not have been earlier than 299 million years ago.

Hair’s origins can be traced back to a common ancestor of mammals, the synapsids. Fossils of synapsids do not usually show hair, but the earliest synapsid stock bore transverse rows of rectangular scutes, similar to those of crocodiles. The age of this acquisition of hair cannot have been earlier than 299 million years ago.

As hair grows, it develops new cells at the base of the root, which grow through the skin. As new cells form, these cells are cut off from nourishment, start keratinization, and die. The dead cells make up the shaft of the hair. This process takes several years, and hair is present everywhere on the body except the palms. The human body is covered with follicles, which produce fine vellus hair and thick terminal strands.

Hair has three layers: the cortex is the most obvious, and it contains most of the hair’s pigment. This is where the hair grows, and is the reason why hair has a distinct color. The medulla is the innermost layer of the hair, and it is where most of the melanin is found. The cortex is the main component of the hair, but the outermost layer is called the cuticle. The cuticle is one thin layer of cells arranged in a scale-like pattern.

The hair shaft is made of three layers: the cuticle, the cortex, and the medulla. The cuticle cell layer is flat and square, and it is adhered tightly to the cortex cells. It is attached to the cortex cells, which are located in the middle of the shaft. It also has the function of providing a barrier against physical and chemical insults. The medulla cells are flat and square. These layers are also the most visible part of the body.

The inner root sheath is the innermost layer of the hair shaft. This layer is called the cuticle and interlocks with the hair cuticle to secure the presumptive hair to the follicle. In addition, the outermost layer of the inner root sheath is called the Huxley layer, and the outermost is the Henle’s layer. These layers are keratinized and form the base of the hair.
