A hair follicle anchors each hair into the skin. The hair bulb forms the base of the hair follicle. In the hair bulb, living cells divide and grow to build the hair shaft. Blood vessels nourish the cells in the hair bulb, and deliver hormones that modify hair growth and structure at different times of life.

The scalp receives a rich arterial supply via the external carotid artery and the ophthalmic artery (a branch of the internal carotid). There are three branches of the external carotid artery involved: Superficial temporal – supplies the frontal and temporal regions.

Summary: Researchers at Massachusetts General Hospital (MGH) have been able to grow hair faster and thicker on mice thanks to a protein that promotes blood vessel growth in their skin.

While the relationship has not been well defined, the blood supply is an essential component of successful hair follicle growth, maturation, and maintenance. The lymphatic vasculature within the dermis supplies the hair follicles as well and participates in the skin immune response.

MORE WAYS TO BOOST BLOOD FLOW

1. Hydrate better!
2. Drink more green tea.
3. Limit salt intake.
4. Take a good multivitamin/mineral, vitamin D, magnesium and an omega-3 EPA/DHA supplement daily.
5. Support your memory with ginkgo biloba extract.
6. Enjoy an ounce of dark chocolate every day (for the cocoa flavanols)

Symptoms of poor blood flow to the brain

• slurred speech.
• sudden weakness in the limbs.
• difficulty swallowing.
• loss of balance or feeling unbalanced.
• partial or complete loss of vision or double vision.
• dizziness or a spinning sensation.
• numbness or a tingling feeling.
• confusion.

Now what were those simple things that must be practiced for increasing oxygen to the brain? Here they are: 1) Breathe easily and normally with your belly in a relaxed way. 2) Breathe through your nose under normal conditions and not your mouth. 3) Take short walks throughout the day.

Contrary to accepted knowledge, blood can bring more oxygen to mice brains when they exercise because the increased respiration packs more oxygen into the hemoglobin, according to an international team of researchers who believe that this holds true for all mammals.

Despite its name, vitamin O is not a vitamin. It claims to be a liquid form of oxygen that can be used as a medicine. However, vitamin O is more likely to be nothing more than water and minerals.

Symptoms of low blood oxygen levels

• shortness of breath.
• headache.
• restlessness.
• dizziness.
• rapid breathing.
• chest pain.
• confusion.
• high blood pressure.

Dizziness, lightheadedness and/or fainting spells: Feeling dizzy or lightheaded and/or fainting is a common indication that your body is not getting the oxygen it needs. A floating feeling or feeling the frequent need to yawn may also occur.

When your body is low on oxygen, you feel tired. Fatigue comes more quickly when your lungs can’t properly inhale and exhale air.

If blood oxygen levels are too low, your body may not work properly. Blood carries oxygen to the cells throughout your body to keep them healthy. Hypoxemia can cause mild problems such as headaches and shortness of breath. In severe cases, it can interfere with heart and brain function.

There is no evidence that any smartphone technology is accurate for the measurement of blood oxygen saturation for clinical use. Furthermore, the scientific basis of such technologies is questionable. Oxygen saturation levels obtained from such technologies should not be trusted in the clinical assessment of patients.

The Blood Oxygen app on your Apple Watch will occasionally measure your blood oxygen levels if background measurements are on. Blood oxygen measurements use a bright red light that shines against your wrist, so it may be more visible in dark environments.

Smartphone-based tool MFine Pulse can monitor blood oxygen using just a finger and a flash. Currently in beta testing for Android users, the tool – dubbed MFine ‘Pulse’ – is due to make its iOS debut in a few weeks.
