DHT, a hormone generated from testosterone that is suspected to be a factor in some people’s hair loss. Can impair circulation and rob hair follicles of blood and essential nutrients. However, despite the fact that it seems as though blood supply keeps follicles happy and healthy. There is still debate about whether a decreased blood supply is actually to blame for hair loss. That is, if there is a relationship between alopecia and blood circulation.
According to studies, the length of the anagen, or growth, stage, of your hair growth cycle, has a significant impact on the length of your hair. Blood flow in the scalp, the mechanism that transports oxygen and nutrients to the hair follicle. Is the cornerstone of these activities. The blood flow to your hair follicles can be impacted by a variety of things. Including your lifestyle, the items you use and don’t use, your diet, and your heredity. All this can be related between alopecia and blood circulation.
In an effort to determine whether improving blood flow to the scalp and to the hair roots promotes hair development. We closely examine the connection between alopecia and blood circulation.
The structure of the hair follicle
The epidermis, also known as the outer layer of skin. The dermis, also known as the middle layer of skin. And the subcutis, also known as the hypodermic layer of skin. Form the three primary layers that make up your skin, including the skin on your scalp. The base of your hair follicles can be found in the lower part of the dermis. Close to the boundary between the dermis and the subcutaneous fat tissue.
The lower third of the hair follicle is encased in a dense vascular plexus. Which can be thought of as a network of blood vessels. It is also tangled up in nerve. Which can be traced all the way back to our brains and nervous systems because of this. This is what causes our hair to “stand up,” or become erect. Whenever our bodies are exposed to cold temperatures. Or when we are experiencing intense emotions such as fear.
Importance between alopecia and blood circulation
When it comes to the circulation of blood to the hair. The subcutaneous fat tissue that lies beneath the skin. Plays an extremely important role.
Your blood vessels benefit from this by receiving a gentle cushioning from it. Which relieves the unwanted pressure that was previously placed on them. In that case, the absence of this cushioning may cause them to shrink. Which in turn will result in a diminished supply of blood to your follicle. You can think of this as a soft soil for the root network of a plant to develop in. It is much easier for the root to develop in softer soil. That is soil that has a fatty tissue underneath it – than it is in soil that does not.
The fact that hair follicles are able to renew and reconstruct themselves over the course of the hair cycle. Is suggestive of the presence of stem cells that are intrinsic to the follicles themselves. It was previously believed that stem cells were located at the bottom of the follicle. However, recent research has shown that these cells are actually located in the bulge region. Which is the shared part in the middle of the outer root sheath.
Not only the hair follicles, but also the sebaceous glands and the epidermis. Can be regenerated with the help of bulk stem cells. Which have a high capacity for proliferating (multiplying) and a high regenerative potential. As a side effect of chemotherapy. Some patients experience this as a contributing factor in their hair thinning.
Alopecia and Blood Circulation
A vicious cycle known as hair follicle miniaturization occurs when a hair follicle doesn’t receive enough blood. In this stage, the follicle gets smaller and needs less blood flow. The pace of hair development and hair thickness are further slowed down by the reduced blood flow, which also supplies less nutrition to the follicle.
No matter how they are consumed—as supplements or as part of a healthy diet—those nutrients never make it to the hair follicle. As a result, terminal (thick and visible) hair may eventually develop into vellus (transculent) hair.
Hair follicle minituarization can happen for a variety of reasons as we age, some of these includes:
- The presence of receptors for the by-product of testosterone, dihydrotestosterone (DHT), in the hair follicle sack is what causes androgenic alopecia.
- Women with PCOS or those using hormone replacement therapy (HRT) are also susceptible to developing androgenic alopecia. Foods that create inflammation in the body, such as processed foods high in sugar (white bread, pastries, candies, pop soda, etc.), which increase insulin, can cause the body to produce androgens in women.
- Hair follicle miniaturization, hair loss, and hair thinning are additional side effects of oestrogen decrease in menopausal women.

Does deficiency in blood circulation cause baldness?
When new grafts are transplanted into places that do not have a good blood supply, the blood supply does rise. This is true even if there is a strong correlation between the amount of hair and the amount of blood supply, it has even been discovered that scars or skin grafts with no hair will have an increased blood supply.
Due to the fact that these places have been implanted with new follicles that will survive, changes in the scalp circulation are not completely known. Another possible factor in hair loss is the constriction of the muscles in the scalp. This is especially common in those who have concerns with dystonia, which is a disorder characterized by abnormal muscular contractions, as well as other illnesses such as temporomandibular joint dysfunction.
This illness, which is more often referred to as TMD, causes people to clench their teeth and grind their teeth during the night, which can lead to chronic tension in the muscles of the forehead and scalp. Finally, according to a recent study, anxiety can play a role in hair loss, which may be related to a decrease in blood flow and circulation.
How to make more blood flow to the scalp?
Popular treatments for hair loss as a result of low blood flow include the following:
- The inversion method, which physically induces higher blood flow to the scalp
- Scalp massages, which stimulate blood flow to the head
- Caffeine, which is a common stimulant included in hair growth serums
- Derma rolling to induce microwounding and the formation of collagen, in addition to enhancing blood flow.
- Castor oil, which contains ricinoleic acid as its primary active ingredient, is known to stimulate the formation of keratinocytes and increase blood flow to the hair follicles.
All of these things help the multiplication of stem cells, which is necessary for supporting new hair development and strengthening existing hair follicles. A condition known as hair miniaturization, which is typically associated with aging, has been observed to go into remission when topical stimulants for blood flow have been applied on multiple occasions.
