The medulla is the innermost layer of the hair and is made up of densely packed cells. It is the only part of the hair that has a direct connection to the blood supply. The medulla is responsible for the hair’s color, texture and strength.

What does the medulla in hair do?
The medulla is the innermost part of the hair shaft. It is made up of loosely packed cells and is not visible to the naked eye. The medulla is responsible for the hair’s strength and elasticity. It also helps to distribute the natural oils that keep the hair healthy and shiny.
Does everyone have a medulla in their hair?
The short answer to this question is, yes, everyone has a medulla in their hair. However, the medulla is not always visible and can be quite thin. The medulla is the innermost layer of the hair shaft and is responsible for transporting nutrients and oxygen to the hair follicle. It is also responsible for making the hair shaft rigid, which helps to protect the hair from damage.
The medulla is not always visible because it can be quite thin. In some cases, it may only be visible when the hair is wet. The medulla can also be obscured by the hair’s cortex and cuticle. If the hair is light in color, the medulla will be more visible. If the hair is dark in color, the medulla will be less visible.
The medulla is important for hair health, because it helps to transport nutrients and oxygen to the hair follicle. The medulla is also responsible for making the hair shaft rigid, which helps to protect the hair from damage.
What does a hair medulla look like?
The hair medulla is the innermost part of the hair shaft. It is a core of soft, spongy tissue that is surrounded by harder hair cells. The medulla is made up of cells called keratinocytes, which are the same cells that make up the hair shaft and the scalp.
The medulla is responsible for the hair’s color and texture. It contains pigment cells that produce melanin, the substance that gives hair its color. The medulla also contains cells that produce keratin, the tough, protein-based substance that makes hair strong and resilient.
The medulla is not always visible. In thin, fine hair, it may be hidden by the hair shaft. In thick, coarse hair, the medulla may be visible as a core of soft tissue in the center of the hair shaft.
The medulla is not a necessary part of the hair shaft. It can be removed without damaging the hair. However, the medulla is important for the health of the hair. It helps to protect the hair shaft and keep the hair healthy and strong.
What does it mean if you don’t have a medulla in your hair?
When you look at a strand of hair under a microscope, you’ll see three main regions: the cuticle, the cortex, and the medulla. The cuticle is the outermost layer, and it’s made up of tough, dead cells that protect the cortex and the medulla. The cortex is the middle layer, and it’s made up of living cells that contain the hair’s color and texture. The medulla is the innermost layer, and it’s made up of delicate, living cells.
If you don’t have a medulla in your hair, it means that the innermost layer is missing. This can be caused by a number of things, including genetics, age, and illness. It doesn’t usually cause any problems, but it can make the hair more prone to breakage.
What happens if medulla is damaged?
The medulla is a part of the brain that is responsible for a variety of essential bodily functions, such as breathing, heartbeat, and blood pressure. If the medulla is damaged, one or more of these vital functions may be affected.
Damage to the medulla can result from a number of causes, including stroke, head injury, or infection. Symptoms can vary depending on the specific function that is affected. For example, if the medulla is damaged and results in a loss of breathing, the person may experience shortness of breath, difficulty breathing, or even respiratory failure.
If the medulla is damaged and results in a loss of blood pressure, the person may experience dizziness, lightheadedness, or even fainting. Damage to the medulla can also cause a change in heart rate, such as a slowed heart rate or an irregular heart rhythm.
If you experience any of these symptoms, it is important to seek medical attention right away. The medulla is a vital part of the brain and any damage can be serious. Treatment will depend on the specific cause of the damage and may include medication, therapy, or surgery.
What are the 3 stages of hair growth?
There are three stages of hair growth – anagen, catagen, and telogen.
The anagen phase is the active growth phase of the hair follicle, and it can last anywhere from two to six years. During this phase, the hair follicle is fed by the dermal papilla, which is located at the base of the follicle.
The catagen phase is the transitional phase, and it lasts two to three weeks. During this phase, the hair follicle begins to shrink, and the cells that make up the hair shaft die.
The telogen phase is the resting phase of the hair follicle, and it lasts around three months. During this phase, the hair follicle is dormant, and the hair shaft is released from the follicle and falls out.
Does African hair have a medulla?
There is a lot of debate surrounding the presence of a medulla in African hair. Some people believe that the medulla is not present in African hair, while others believe that it is. So, what is the truth?
Well, the fact is that there is no definitive answer to this question. Different people seem to have different opinions on the matter. However, there is some scientific evidence that suggests that the medulla may be present in African hair after all.
A study that was published in the journal ‘PLoS One’ in 2016 looked into the presence of a medulla in African hair. The study involved examining the hair of people from different African countries, as well as people from other parts of the world. The results of the study showed that the medulla was present in the African hair samples, but not in the other hair samples.
This study provides some evidence that the medulla may be present in African hair. However, it is important to note that more research is needed in order to confirm this. So, at this point, it is still unclear whether or not African hair has a medulla.
