Hyperbaric Oxygen Therapy Hair Growth

Hyperbaric Oxygen Therapy (HBOT) is scientifically proven to stimulate hair growth, but it works best as a “Cellular Re-activator” for dormant follicles rather than a cure for total baldness.

HBOT’s central role is to attack the root cause of hair follicle degeneration: hypoxia (Hypoxia). Breathing in 100 percent pure oxygen at a pressure of 1.5 to 2.0 ATA (absolute atmospheric pressure), your plasma can absorb up to 15 times more oxygen than usual. This extreme state of oxygenation triggers two mechanisms that are critical for hair regeneration:

Angiogenesis (Angiogenesis): forces the body to create new microvessels (capillaries) around shrinking hair follicles, reestablishing nutrient supply lines that have been cut by DHT or aging.

Cycle Resetting: Significantly reduces inflammation around the hair follicle and forcibly pushes the follicles stuck in the “resting phase” (Telogen) back to the “anagen phase” (Anagen).

Understanding The “Cellular Re-activator” Mechanism

To understand how hyperbaric oxygen therapy promotes hair growth, we need to look at the bottom drivers of hair loss. In addition to hormones, the most important thing is oxygen hunger (oxygen Starvation) at the cellular level. Hair follicles are one of the most metabolically active cellular tissues in the human body, and they require huge amounts of oxygen and energy to maintain hair production. When hair follicles begin to be miniaturized (miniaturize) due to aging or genetic factors, the local microenvironment becomes “hypoxic”.

HBOT acts as a “cell activator” in a way that changes the physical rules of oxygen delivery. Under normal circumstances, oxygen is transported mainly by red blood cells. However, in the hyperbaric chamber (pressurized to 1.5 to 2.0 ATA), the laws of physics (especially Henry’s law) come into play, allowing oxygen to be dissolved directly into the plasma. This causes a surge in oxygen levels in the plasma-up to 15 times the normal level. This supersaturated oxygenated plasma can reach tissues with impaired blood circulation-which is where red blood cells usually don’t get in-and reach deep into the scalp to “wake up” hair follicles that have been dormant due to lack of fuel.

New Blood Vessel Formation

The first specific biological mechanism triggered by this influx of oxygen is angiogenesis. This refers to the physiological process of differentiating new blood vessels from existing ones.

Hair loss tends to accelerate when the blood supply to the hair follicles is impaired. Factors such as DHT (dihydrotestosterone) and aging cause the capillaries that feed the hair roots to contract and restrict blood flow. This is equivalent to cutting off the necessary nutrients for the hair to grow thick.

The germinal regimen of hyperbaric oxygen therapy is actually “forcing” the body to initiate angiogenesis. By signaling the release of vascular endothelial growth factor (VEGF), HBOT encourages the creation of a new microvascular network around the atrophied hair follicles. This actually plays a 3 role:

Rebuilding “supply lines”: restoring the delivery of vital nutrients.
Energy supply: ensure that dormant hair follicles get the energy needed to restart protein synthesis.
Reversing miniaturization: combating the process of hair follicle atrophy due to restricted blood flow.

HBOT Resets The Hair Cycle

The second key mechanism of HBOT is its ability to manipulate the hair growth cycle by controlling inflammation, specifically, moving hair follicles from the “telogen” to the “anagen” phase “.

Combating Perifollicular Inflammation

A major obstacle to hair growth is perifollicular inflammation (perifollicular inflammation)-1 chronic, low-level swelling around the hair root that actually signals the follicles to stop growing and shed their hair shafts. This inflammation usually causes the hair follicle to be trapped in the resting phase (resting/shedding phase) for a long time. HBOT is the potent anti-inflammatory treatment. By filling the scalp tissue with oxygen, it can significantly reduce the inflammation around this hair follicle. Once the inflammation subsides, the suppression of the hair follicle is relieved.

Transition To The Growing Period

When the inflammation is cleared and oxygen levels are restored, so-called “cycle reset” occurs. Hair follicles are forced out of dormancy and pushed back into anagen (Anagen). This is why users of hyperbaric oxygen therapy often report that abnormal shedding stops at first, followed by thickening of existing hair-as more hair follicles enter the active growth phase at the same time.
