Anti-Aging, Hair Growth, Gray Hair, Baldness, Beauty Myths & Beauty Truths, Dermarolling vs. Microneedling, Scars & Stretch Marks, Testosterone, DHT & Much More With Dr. Cameron Chesnut | Ben Greenfield Fitness

Key Takeaways

  • Microneedling builds structural strength and resilience in the skin
  • Microneedling can be done on the face or the scalp to stimulate hair growth
  • Dermarolling is the home version of microneedling but does more harm than good because of the method used to break the skin barrier and trauma caused
  • Elastin is actually more important than collagen in the elasticity and appearance of skin
  • It’s best to know the underlying cause of hair loss – but C60 and GHK copper peptide are mechanistically sound methods to assist hair growth
  • Vasodilation is an underlying component to many hair growth treatments: try sauna, hyperbaric chamber, infrared light, massage
  • Hair transplantation is the best way to improve the look of hair and has come a long way
  • Laser treatment is the best route to reduce the appearance of scars
  • Collagen stimulating injection may help with stretch marks, depending on the depth
  • If your diet is sound, you won’t need to supplement with collagen and keratin – it doesn’t work the way you hope it will

Introduction

Dr. Cameron Chesnut (@chesnut.md) is a renowned surgeon and innovator in both minimally invasive and non-surgical cosmetic procedures. Dr. Chesnut is an expert on both the art and science of aging and a leader in dermatologic and cosmetic surgery. Dr. Chesnut recently opened a new full-service biohacking facility and clinic in Spokane, Washington called ÔPTIM.

In this episode, Ben Greenfield an Dr. Cameron Chesnut unpack questions regarding hair growth, gray hair, male and female pattern baldness, skin beauty treatments, fixes for scars and stretch marks, and much more!

Microneedling

  • Microneedling builds structural strength and resilience in skin
  • Creates crude injury that acts as a stimulus
  • The procedure opens blood vessels in the face and allows growth factors (such as platelet-rich plasma) to seep in
  • Microneedling in hair: targeting stem cells in the hair bulb
  • Microneedling in the face: targeting fibroblasts that create new collagen and elastin
  • Collagen provides the structural strength, but the elastin is what’s more important in the elasticity of the skin
  • Building elastin takes weeks to months
  • What to expect with Microneedling treatment:
    • In face: mild injury, 12-14 hours of redness and rawness, back to life by 36-72 hours; looks really good during initial swelling because wrinkles are less defined
    • In hair: first injection stimulates stem cells to trigger the growth phase of hair
  • Infrared, hyperbaric chambers can assist in quicker recovery from procedures and enhance benefits

Dermarolling Vs. Microneedling

  • Dermarolling is the home version of microneedling, trying to break the skin barrier and allow growth factors or other home treatments to enter
  • Microneedling: needles penetrate perpendicular to the skin, new needle is used every time, controlling depth with precision
  • PRP is really the benefit of the microneedling treatment and you can’t do that at home
  • Dermarolling: tends to cause tearing injury to the surface of the skin because the roller is moving tangentially, not as strategic
  • Dermarolling can cause more harm than good because it can induce more trauma with less penetration
  • Scrubs similarly cause epidermal damage

Collagen And Keratin Supplementation

  • As we digest collagen, we’re breaking down into amino acids and reassembling into protein we need
  • Collagen doesn’t get consumed then targeted in skin or hair where we are probably hoping to improve
  • Keratin is made in our bodies so it’s the same idea – you won’t consume keratin then immediately channel it to hair, skin, and nails
  • If you are nutritionally sound, you won’t need collagen or keratin supplement

Hair Growth & Loss

  • The strongest indicator of hair loss is stress level
  • Anything angiogenic in the scalp can be helpful in hair growth
  • Mechanistically, C60 assists with grey hair but we need to know the root cause of hair loss
  • GHK copper peptide: improves hair you already have, stimulates hair growth
  • Angiogenesis can be increased by hyperbaric chamber and blood flow restriction chamber
  • Ketoconazole shampoo is prescribed if you have any fungal issues or dandruff on the scalp
  • Massage and microcirculation may stimulate scalp and hair growth via vasodilation
  • Vasodilation is the underlying ingredient in many hair growth hacks: sauna, infrared light, lasers, light therapy, massage
  • Suppression of mTor via rapamycin could have an effect on hair color and hair growth
  • Caution: mTor and rapamycin have effects on many parts of the body so not recommended for just a hair hack
  • For grey hair: balance iron to copper ratios which effects oxidative capacity

Relationship Between Testosterone Levels & Baldness

  • Androgen paradox: hair follicles are sensitive to testosterone which determines where we grow hair – but generally, men with male pattern baldness have higher testosterone
  • Testosterone is producing high DHT which leads to baldness
  • Mechanism of DHT and pattern baldness is not fully understood because it’s doing something different at the top of the scalp than behind the head
  • Theory: hair loss takes place where the gravitational pull is highest
  • Solution: increase the activity of stem cells in adipose tissue around hair follicles
  • Inversions and yoga trapeze could possibly help with hair growth but haven’t been studied

Hair Transplantation

  • Simple to do, done while awake, most restorative and natural way to improve the look of hair
  • Follicular Unit Extraction (FUE): precisely go after individual hair follicles and reimplant them in another part of the scalp
  • Typically, hair for FUE is taken from the back of the scalp and implanted in the desired area
  • You can take body hair and use it for FUE – over time, it will take on the characteristics of the hair on your head

Scars & Stretch Marks

  • Scars are caused by injury to an area that created the body’s need to heal but the skin doesn’t have the consistency of normal skin
  • Scars are the buildup of collagen in the area which makes the skin a different texture
  • The most basic thing to do is use a laser to stimulate skin and trigger it to behave like normal skin
  • Fat injections into scar will create more vascularity
  • Stretch marks are usually formed from weak part of the skin that failed
  • Stretch marks: epidermis intact, the dermis is separated
  • Solutions to try for stretch marks: red light therapy, biostimulants (such as collagen-stimulating injection Sculptra), laser to restructure

Can There Be Too Much Therapy?

  • Many studies have looked at symmetry and found that society looks more favorably upon symmetry
  • We are wired to appreciate beauty and symmetry
  • The social norm of what’s acceptable and desirable is different depending on where you live
