Episode notes

INSIGHT

Follicle Environment Drives Hair Growth

Hair follicles need high oxygen and healthy mitochondria to produce hair.
Excess DHT, inflammation, and scar tissue impair the follicle environment and stop growth.

INSIGHT

DHT, Hypoxia, And Scar Tissue Link

Aging shifts testosterone to higher DHT which can shrink follicles and cause hypoxia.
Scar tissue from inflammation then prevents hairs from regrowing despite hair existing elsewhere.

INSIGHT

Insulin Resistance Is A Key Driver

Genetics matter but are not the only cause; enzyme activation and receptor sensitivity play roles.
Insulin resistance is the strongest driver increasing 5-alpha-reductase activity and free testosterone conversion to DHT.

Today, I’m going to show you how to reverse hair loss naturally, without damaging side effects. Most hair loss is androgenic, typically resulting in male pattern baldness and thinning hair in women. The hair follicle requires significant oxygen and mitochondria for optimal hair growth.

Testosterone decreases with age in both men and women and is replaced by DHT, a more powerful form of testosterone. Many hair regrowth treatments work by inhibiting DHT.

Too much DHT can decrease hair growth, reduce oxygen, increase inflammation, and increase scar tissue in the hair follicle. Drugs for hair growth that work by lowering DHT can come with side effects like decreased libido and erectile dysfunction.

Beyond age and genetics, the primary driver of DHT is insulin resistance!

To reverse hair loss and stimulate hair regrowth, you must support the environment of the hair follicle. Mechanical scalp stimulation is one of the most overlooked yet effective remedies for hair loss, with microneedling being the most effective method.

Other natural remedies for hair loss include:

•Red light/NIR light

•Rosemary oil (natural Rogaine)

•Correcting insulin resistance. This FREE mini course can show you how: https://drbrg.co/4pBHk9O

•Increase zinc (30-40 mg) and vitamin D (10,000 IU)

•Natural 5 alpha-reductase inhibitors: saw palmetto, pumpkin seed oil, EGCG, peppermint oil, zinc
