What is Genetics of Baldness?
BY DR. DEEPTHI SRINIVAS · PUBLISHED FEBRUARY 19, 2021 · UPDATED FEBRUARY 21, 2021
Baldness is also known as alopecia, it is the most common problem faced by all age sector people. It is nothing but absence or hair fall from a region. It is most commonly seen on the scalp , but can be seen in other body regions as well. So the next question arises in the mind, Why is baldness seen? What are the causes? Is there a cure for it?
Let’s see the answer below in the article.
Causes of baldness include hereditary, certain medical conditions, hormonal changes, lifestyle and as a normal sign of aging. So genes for baldness are transferred to the next generation? Answer is yes. Baldness is inherited to the next generation. If the parent or parents are blad , it is more likely found that the child will inherit it.
Types of baldness
Alopecia totalis (complete hair loss in the scalp region)
Alopecia areata (hair loss seen in patches)
Diffuse alopecia ( hair loss seen in diffuse pattern)
Many other types may also be seen based on various factors. But above 3 types are most commonly seen.
So which are the genes involved in transmitting to next generations?
The most important genes involved in these characteristics are AR GENE. These genes are usually seems to be present on the X chromosome. It is an autosomal dominant gene. Not only this gene determines baldness in an individual ,there are various other genes, believed to be more than 65 various genes which are involved in baldness not only genes causes baldness, but lack of nutrition, hormonal imbalance, aging can also cause baldness. Baldness due to these factors can be tried to be reversed by various medical , natural or surgical procedures, but baldness due to genetics cannot be reversed as the hair follicle is permanently damaged or is dead.
Let’s see how a male or female child inherits this genes. We know that we have 23 pairs of chromosomes. In which the male child inherits XY chromosomes from the parents and the female child seems to inherit the XX chromosome from the parents. As the AR gene is seen to be present on the X chromosome, male children are more likely to inherit the baldness as compared to the female child who is recessive or carrier of the genes and just transmits the characteristics to the next generations. While in the male it is the dominant characteristic seen.
As seen in the above image, male children seem to be affected more than the female children. The sex of the child cannot be controlled , but preventing from the future generations from becoming bald can be saved.
Implanting healthy lifestyle in the child from the early days,with foods rich in vitamin E help in forming healthy hair follicles. Balanced diet , adequate hydration to the body, reducing stress helps to strengthen the hair and slow the process of baldness.
So what are the various treatments available?
Yes baldness is definitely a curable disease.
Laser therapy
Artificial replacements
Hair transplantations
Plasma injections
Diet counselling
Topical medical applications
No matter which gender , baldness might affect anyone due to present day stress, lifestyle wherein we can see ballness at every young age. Though external beauty is not of much importance when compared to the internal beauty , in the present day people with baldness are very less acceptable. This inturn lowers the confidence of the individual.
Hence people must be well educated about the medical process of baldness and to make the fact to go out from the society to treat people being bald as aliens and to accept them as normal. With increased technology, any disease can be treated. Let it be a genetic disease or even a small virus. Medicine as always provide stronger impact, along with the will power of an individual.
