Which Hair Structure Contains Melanin to Give Hair Its Natural Color?

Understanding the hair structure and the role of melanin in determining natural hair color is essential for anyone interested in hair care and styling. This article aims to provide a clear and concise overview of the topic, highlighting the positive aspects and benefits of knowing which hair structure contains melanin. Whether you are a hairstylist, hair enthusiast, or simply curious about your own hair, this information will prove valuable.

I. Importance of Melanin in Hair Color

  • Melanin: The pigment responsible for hair color
  • Determining hair color: Different types and amounts of melanin
  • Role of melanocytes: Cells that produce melanin

II. Hair Structure and Melanin Distribution

  • Hair follicle: The structure from which hair grows
  • Hair shaft: The visible part of the hair
  • Melanin distribution: Concentrated in the cortex of the hair shaft

III. Benefits of Understanding Melanin and Hair Structure

  • Hair color knowledge: Helps in making informed decisions about hair dyeing and styling
  • Hair health: Understanding melanin distribution aids in maintaining hair's natural strength and resilience
  • Hair care routines: Tailoring hair care products and practices to
Cortex. As the middle layer, the cortex gives your hair its appearance, texture, and elasticity. This is where you'll find melanin, the pigment which gives your hair its color. Hair becomes grey when a lack of melanin is produced in the hair shaft.

What part of the hair contains the pigment responsible for the hair color?

The cortex forms the main bulk and pigment (colour) of your hair. It consists of long keratin filaments, which are held together by disulphide and hydrogen bonds. The health of your cortex depends largely on the integrity of the cuticle protecting it.

What substance in the cortex gives natural color to the hair?

It gets its natural color from a type of pigment called melanin. The formation of melanin begins before birth. The natural color of our hair depends upon the distribution, type and amount of melanin in the middle layer of the hair shaft or cortex.

What does the hair medulla do?

The medulla is the inner layer of the hair and is loosely packed and disorganized. The medulla does not really do anything, but its DNA tells us from which species it comes, and from where on the body that hair would have been found.

Where is melanin found in the hair structure?

Melanin granules are mainly in the cortex, their long axis being parallel to the hair surface. The cuticle cells contain few or no melanosomes. Usually, no melanin is seen in the cells of the inner root sheath. The distribution of melanosomes in the upper part of the outer root sheet resembles that in epidermis.

What does a human hair cuticle look like?

The cuticle is your hair's protective layer, composed of overlapping cells — like fish scales or roof tiles, but facing downwards. A healthy cuticle is smooth and flat. This gives your hair shine and protects the inner layers from damage.

What does an unhealthy hair cuticle look like?

What does a damaged cuticle look like? A damaged cuticle layer looks rough, ragged and uneven. When the cuticle layer is raised, individual hair strands can't fall in smooth, sleek, flat alignment. The overall effect of a raised cuticle layer is dry, dehydrated hair that looks dull, puffy and frizzy.

Frequently Asked Questions

What does a cuticle look like?

The cuticle is the transparent skin located above and around the nail base. The lunula is the half-moon shape seen at the base of the nail. The lunula is located above the cuticle.

What provides hair color in the cortex?

Melanin The cortex of the hair shaft is located between the hair cuticle and medulla and is the thickest hair layer. It contains most of the hair's pigment, giving the hair its color. The major pigment in the cortex is melanin, which is also found in skin.

What substance in the cortex gives the hair color?

Melanin Elongated cells form a fibrous substance that gives strength and elasticity to the hair. The cortex also houses the pigment (melanin) that gives hair its natural color.

Does the cortex may contain pigment granules?

The cortex is the main body of the hair composed of elongated and fusiform (spindle-shaped) cells. It may contain cortical fusi, pigment granules, and/or large oval-to-round-shaped structures called ovoid bodies.


Which section of the hair shaft contains pigment granules that give hair color?
Cortex Cortex. The cortex gives hair its color and shape. There are three main features found in the cortex – melanin (the pigment that gives hair its color), cortical fusi (irregular shaped air spaces of varying size), and ovoid bodies (large solid structures that are round with regular margins).
Where are pigment granules located in human hair also where are they most concentrated?
Melanin is concentrated inside melanosomes, which are specialized pigment-producing organelles. These melanosomes are first created by melanocytes, then transferred to keratinocytes in hair follicles, and later relocated to the hair shaft/cortex (6, 7).
Where are pigment granules stored?
Within the melanocyte, the pigment melanin is synthesized and stored in an organelle, the melanosome. Later, the pigment is transferred to the keratinocyte in a new organelle that is positioned near the nucleus to protect the genetic material against the harmful effects of UV radiation.
What is hair made up of?
Most of the cortical cells are composed of a protein known as keratin (Robbins, 2012). At the molecular level, keratin is a helical protein (Pauling & Corey, 1950). There are two types of keratin fibres that exist in hair: type I with acidic amino acid residues and type II with basic amino residues.

Which hair structure contains melanin to give hair its natural color?

What is the chemical makeup of the hair? Essentially composed of keratin, hair also contains other elements and molecules that contribute to its appearance and behaviour. The overall chemical composition of hair is 45 % carbon, 28 % oxygen, 15 % nitrogen, 7 % hydrogen and 5 % sulphur. The hair shaft is essentially composed of keratin.
What is the composition on hair? In addition to water, the elements that compose the chemical composition of hair are: keratin, lipids, minerals and pigments. Keratin is a protein found in the cortex. Keratin is composed of 18 amino acids.
What are the three main parts that makeup hair? The three inner layers become the hair, made up of the cuticle, the cortex and the medulla (although the medulla isn't always present, especially in hairs with a thinner diameter).
  • Is hair made up of cells or not?
    • Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells.
  • Pigment granules that impart hair with color are found in which layer of the hair?
    • Pigment granules that impart hair with color are found in the: Cuticle. Medulla. Cortex. Both A and B. Scale pattern. Which feature of hair is MOST important 
  • Which hair structure contains melanin to give hair its natural color
