What is the cuticle of the hair?
The hair’s outermost layer, the cuticle, is made up of overlapping shingles, also known as scale cells. The cuticle is part of what makes up the hair shaft. These cells function defensively to protect the inner structure of the hair. By doing so, these cells help to regulate the water content of the hair fiber.
How does the cuticle layer affect the appearance of hair?
The appearance of the hair depends largely on the health of the cuticle, the protective sheath of the whole hair. If you’re on a journey to grow long hair, take this quote to heart. The cuticle layer of human hair is the most important factor in hair growth. Without a healthy cuticle layer, you can expect to never reach your long hair goals.
What are the scales of the cuticle layer made of?
The scales of the cuticle layer are made up from a special protein called keratin. Keratin is fibrous, high-sulfur protein found in hair, skin, and nails. Now keratin does indeed give such delicate things such as hair and nails strength, but that doesn’t mean that it can’t be damaged.

A thin coat is painted on a glass microscope slide or, if the lacquer is thinned with acetone, a drop may be allowed to run down the surface of the slide. The hair to be cast is placed on the slide and allowed to dry. When the surface has dried, the hair is removed to reveal the scale pattern.
How many layers of cuticle scale does coarse hair have?
Each hair shaft is made up of two or three layers: the cuticle, the cortex, and sometimes the medulla. The cuticle is the outermost layer. Made of flattened cells that overlap like the tiles on a terra-cotta roof, the cuticle protects the inside of the hair shaft from damage.
What is the cuticle of an insect?
The cuticle is the outer covering of the insect and is its exoskeleton to which the muscles are attached (Fig. 1). The outermost layer is called the epicuticle; under this is the exocuticle followed by the endocuticle.
Why is the cuticle a vital component of the natural nail?
The cuticle plays an important role in the health of your nails. They provide a protective cover for the tissue that grows new cells that build the nails. As you know, your nails are constantly growing -- that's why you have to keep clipping them.

What is the function of the earthworm's cuticle?
The worm's skin is protected by a thin cuticle and kept moist by a slimy mucus. This lets it absorb the oxygen it needs and expel carbon dioxide. If a worm is dried up by the sun, it will die because the exchange of gases can't take place.
Why do cuticles stay flat?
All cuticle layers aren’t created the same. In fact, the cuticle layer and how its scales naturally align varies according to hair type. For straight, type 1 hair, the cuticle layer hugs the cortex very tightly and the layer’s scales naturally lay flat. This is why straight hair shines more often and tends to stay moisturized for a longer period of time than any other hair type. For curly hair types, the cuticle layer’s scales are naturally raised and don’t lay flat. As a result, curly hair tends to shine less and doesn’t feel as smooth to the touch. Raised cuticles are also the reason why curly hair tends to look frizzy and tangles easily. If your hair falls in between straight and curly, the alignment of the cuticle layer will depend on how tightly your hair curls or waves. Since curlier hair textures have naturally raised cuticles, it’s important that people with highly textured hair take extra care to preserve their hair’s cuticle.
What is the cuticle layer of hair?
If you look at the cuticle layer of the hair under a microscope, it looks very similar to the layout of shingles on a roof. The shingle like structure of the cuticle layer are made up from protein scales within the layer that overlay on top of each other to keep moisture within the hair shaft.
How does the cuticle layer react to the pH of water?
The cuticle layer opens and closes or react s to the pH in substances we use on our hair, including water. Hair has a “happy pH” it likes to be at, between a range of 4 to 5.5, and it’s within this happy pH range that the cuticle layer is able to remain closed. On the other end, when the cuticle layer comes into contact with substances that are outside of this happy pH range, it reacts by opening or raising its scales. Every substance you put on your hair has a pH level, and your hair will react to that pH level by lifting or closing the cuticle layer.
How does the cuticle layer protect the hair strand?
How the Cuticle Layer Functions and Protects the Hair Strand. The cuticle layer consists of protein-based scales that open and close when “activated.”. When these scales rise, chemicals and ingredients can pass through the cuticle layer to the control center of the hair strand, the cortex. The cortex determines the hair strand’s color, curl ...
What determines the color of hair strands?
The cortex determines the hair strand’s color, curl pattern, thickness, and texture. In order for chemical processes, such as hair color or relaxers, to be effective on the hair strand, they have to get past the cuticle layer (think of the cuticle layer as the big brother in large family of kids who protects the younger, more vulnerable kids). ...

How does heat affect the cuticle of hair?
The hair cuticle can be damaged by the overuse of heat from hot tools such as flat irons and curling irons. In addition, chemical treatments such as perms and texturizers can be just as damaging.

What is the function of the cuticle?
Functions of the Hair Cuticle. The cuticle protects the ‘brain’ of your hair: the cortex. The cortex tells the hair strand what to do, from its color, texture and curl pattern to thickness. Additionally, the cuticle helps prevent damage to the cortex. When the cortex is damaged, the hair strand cannot repair itself.
How do cuticles work?

Answer
The cuticle is a transparent outer layer of the hair shaft. It is made of scales that overlap one another and protect the inner layers of the hair (Figure 3-4). The scales point from the proximal end of the hair, which is closest to the scalp, to the distal end, which is far- thest from the scalp
