Secrets of Beautiful Hair: What Hair and Scalp Looks Like

Hair is not only an expression of our individual style, but also a fascinating biological formation that is striking in its structure and function. Let's take a closer look at what hair and scalp look like and what lies beneath the surface of our scalp.

Hair Structure:

                                                                                                         

 

1. Hair Follicle:

Hair grows from hair follicles located in the scalp. These small roots are responsible for the growth and development of hair. Each follicle contains blood vessels that supply nutrients and oxygen, which is essential for hair growth.

 

2. Hair Shaft:

The hair shaft is the visible part of the hair that is above the surface of the skin. The shape and texture of the hair shaft affect how the hair looks. It can be straight, curly, or somewhere in between.

 

3. Keratin:

The main component of the hair shaft is keratin, which is a solid protein that also makes up the nails and cuticles. Keratin provides hair with strength and structure.

 

4. Cuticula:

The hair shaft is surrounded by a thin layer called the cuticle. The cuticula is composed of thin scales that resemble roof tiles. The protective function of the cuticle is to retain moisture and prevent possible damage to the hair shaft.

 

Hair Skin:

                                                                                         

1. Sebáceous Glands:

The scalp contains small sebaceous glands called sebaceous glands. These glands produce an oil known as sebum, which moisturizes the hair and skin and protects it from drying out.

 

2. Follicular Bags:

Around the hair follicles are follicular sacs that contain small muscles known as arrector pili muscles. These muscles are responsible for what we call "goose bumps" or the feeling of hair on our skin when we get a bite.

 

3. Blood Vessels:

Hair is connected to blood vessels, which allows the supply of nutrients and oxygen to the hair follicles. Good blood circulation is crucial for healthy hair growth.

 

4. Melanocytes:

The scalp contains cells called melanocytes, which produce a pigment called melanin. Melanin determines hair colour - eumelanin for dark colours and pheomelanin for light colours.

 

Conclusion:

 

The overall appearance of hair and scalp is the result of a complex biological process. To maintain healthy and beautiful hair, it is crucial to take proper care of it. Proper washing, appropriate products and a healthy lifestyle can make a significant difference in the appearance and condition of your hair. And now that you know what's going on beneath the surface, you can better understand your hair's needs and give it the appropriate care.
