6 Key Concepts
Hair Mass Index (HMI)
HMI is a combined measurement of hair diameter and density in a specific scalp area. It is used to objectively quantify hair loss or improvement over time, even before it's visible to the naked eye, by comparing at-risk areas to permanent zones.
Follicle Miniaturization
This is the process where a healthy, thick 'terminal' hair follicle gradually shrinks, producing progressively shorter, thinner, weaker, and wispier hairs, eventually becoming a 'velous' hair. Once a follicle reaches the velous stage, it's considered beyond repair and unlikely to regain significant growth.
Photobiomodulation
This is the scientific principle behind low-level laser therapy (LLLT) for hair growth. It involves specific wavelengths of light being absorbed by cytochrome C oxidase in the mitochondrial membrane, leading to hyperpolarization and increased ATP production, which fuels stronger hair growth.
Potassium Channel Opener (Minoxidil)
Minoxidil works by opening potassium channels, which helps keep hair follicles in the 'anagen' (growing) phase for longer. This action reduces the number of resting follicles and can lead to thicker, stronger, and healthier hair fibers over time.
Follicular Unit Extraction (FUE)
FUE is a hair transplant technique where individual follicular units (groups of 1-3 hairs) are harvested directly from the donor area using a tiny punch tool, typically about a millimeter in size. This method avoids a linear scar, allowing for more flexible hairstyling and quicker healing of the donor site.
Donor Dominance
This is the foundational theory of hair transplantation, stating that hair follicles from the sides and back of the scalp, which are genetically resistant to DHT, will retain this resistance and continue to grow permanently even when transplanted to a bald or thinning area of the scalp.
10 Questions Answered
Hair loss is very common, affecting almost 100 million Americans, including about 80 million men and 46 million women.
In men, 98-99% of hair loss is genetically determined, with over 200 genes regulating various hair properties, not just tracking from one side of the family.
Male pattern hair loss can start anytime after puberty, with 20% of men in their twenties, 30% in their thirties, and 40% in their forties showing visible signs.
Dihydrotestosterone (DHT) is the primary trigger for male pattern hair loss in genetically susceptible individuals, leading to follicular miniaturization.
Finasteride is contraindicated in women of childbearing age due to risks to a developing male fetus, but it can be used off-label in post-menopausal women with about a 50% success rate if androgen sensitivity is a factor.
Antihypertensives (blood pressure medications), cholesterol-modulating medications, and mood modulators (like SSRIs) are among the top types of medications that can impact hair quality.
Scalp health is vital because microinflammation at the follicle level, often mediated by an inflammasome, can shut down follicles and impair hair growth. Treating issues like fungal overgrowth or psoriasis can significantly improve hair health.
LLLT works by delivering photons of light to the hair follicles, which are absorbed by cytochrome C oxidase in the mitochondria, increasing ATP production and promoting stronger, healthier hair growth.
PRP is a concentrated solution of platelets derived from a patient's own blood. Platelets contain growth factors and cytokines that promote tissue regeneration, repair, and new blood vessel formation, which, when injected into the scalp, can enhance existing follicles and prevent further loss.
Hair transplantation can create the illusion of a full head of hair in totally bald areas by strategically placing grafts, but it cannot restore the original density of a teenager's hairline because it relies on redistributing existing follicles.
26 Actionable Insights
1. Act Early on Hair Loss
Take action soon to protect the functioning of hair follicles before they reach a ‘point of no return’ and miniaturize beyond repair, as once a follicle produces vellus hair, it cannot be revived.
2. Consult a Hair Loss Specialist
Seek out a physician who specializes full-time in hair loss, as they possess the expertise and tools (like trichometers for hair bundle measurements and genetic testing) to accurately diagnose and monitor your specific condition, unlike many general dermatologists.
3. Prioritize Scalp Health
Address any microinflammation or overactivity of yeast populations (like those causing dandruff) on the scalp, as poor scalp health can detrimentally affect hair growth by impairing follicle function.
4. Manage Transplant Expectations
Have a clear and honest discussion with your surgeon about what is realistically achievable with a hair transplant, as the main risk is not physical complications but dissatisfaction if expectations for density or coverage are not met.
5. Consider FUE for Transplants
Opt for Follicular Unit Extraction (FUE) over linear harvesting, as FUE uses tiny punches to harvest individual follicular units without a scalpel or stitches, resulting in minimal scarring and greater flexibility in hairstyling.
6. Use Compounded Topical Minoxidil
Seek compounded minoxidil formulations (e.g., 82M) from a pharmacy, as these are designed to penetrate better, be easier to use, less irritating to the scalp, and can include beneficial ingredients like tretinoin and anti-inflammatories, unlike many over-the-counter options.
7. Apply Minoxidil Correctly & Consistently
Apply topical minoxidil twice daily for 90 seconds, ensuring the applicator tip directly reaches the scalp by parting the hair, as once-daily application is rarely effective and proper technique is crucial for the medication to work.
8. Utilize Low-Level Laser Therapy
Consider low-level laser therapy (LLLT) using a laser cap device, as it’s a non-chemical, side-effect-free treatment that imparts energy to hair follicles, stimulating stronger, healthier hair growth and is a cost-effective long-term investment.
9. Choose Quantified PRP Treatments
Select a PRP (Platelet-Rich Plasma) provider who quantifies the platelet concentration of the injected product, as there’s a strong correlation between the amount of platelets and the clinical outcome, with an optimal range around 1.4-1.5 million platelets per microliter.
10. Inquire About Monocyte-Rich PRP
Ask your PRP provider about their process for creating monocyte-rich PRP, as monocytes are an underappreciated component that can significantly enhance the regenerative effects of the treatment.
11. Understand PRP Treatment Frequency
Expect optimized PRP treatments to be administered approximately once a year, as a well-prepared, high-concentration PRP can provide positive responses lasting 10 to 14 months, rather than requiring monthly sessions.
12. Know PRP Limitations & Benefits
Understand that PRP is not effective for completely bald areas with dead follicles, but it can significantly boost volume (20-50%) in thinning areas and help prevent further follicle function loss.
13. Adopt Combination Therapy
Layer different therapeutic interventions (e.g., systemic medication, topical treatments, laser, PRP) for hair loss, as this multi-modal approach is often more effective than relying on a single treatment.
14. Consider Finasteride for Men
Discuss finasteride (1mg/day) with your doctor for male pattern hair loss, as it has a 90% chance of maintaining or improving hair appearance over the long term by blocking DHT, the primary trigger for follicular homicide.
15. Finasteride for Post-Menopausal Women
If post-menopausal, discuss finasteride with your doctor, as it can be used off-label and has shown a 50% success rate in improving female pattern hair loss, but it is strictly contraindicated for women of childbearing age due to risks to a male fetus.
16. Monitor Medications for Hair Impact
Be aware that medications for blood pressure, cholesterol, and mood modulation can negatively impact hair quality; reflect on when you started these medications if you notice changes in your hair.
17. Use Biotin as an Adjunct
Take high-dose biotin (e.g., 10,000 micrograms) if recommended, as it can improve keratin production and strengthen existing hair, but it must be coupled with other effective treatments as it won’t cure hair loss on its own.
18. Always Condition After Shampooing
Follow every shampoo with a conditioner, as shampoo cleanses and can strip natural oils, while conditioner replaces moisture to keep hair healthy and prevent dryness and damage.
19. Tailor Conditioner to Hair Type
Choose conditioners based on your hair type: use durable conditioners for long, curly, or kinky hair, and very light conditioners for thin or limp hair to achieve desired weightlessness and style.
20. Treat Underlying Scalp Conditions
If you have severe scalp conditions like psoriasis or chronic dandruff, seek appropriate medical treatment to resolve these issues, as they can significantly impair hair growth.
21. Seek Artistic Transplant Design
Choose a hair transplant surgeon who employs an artistic approach to hairline design, considering the angle, orientation, position, and density variation of hairs to create a natural, undetectable result that complements your face and age.
22. Consider Two-Day FUE for Large Cases
For large hair transplant procedures (over 2000 grafts), discuss splitting the FUE into two consecutive days, as this approach enhances patient comfort, improves harvest rates, and ensures better graft quality.
23. Explore Alternative Donor Sites
If scalp donor hair is insufficient (e.g., due to previous harvesting or extensive baldness), discuss using beard or body hair as alternative donor sites, with beard hair being particularly effective for filler in the back of the scalp.
24. Utilize Women’s FUE Techniques
If you are a woman considering FUE, ask about partial shaving or ’no-shave’ techniques where only a few hairs are trimmed from the donor area, allowing you to maintain your current hairstyle during the process.
25. Debunk Hair Loss Genetic Myth
Do not solely rely on your maternal grandfather’s hair pattern to predict your own hair loss, as hair loss genetics are complex and involve factors from both sides of the family, not just X-linked inheritance.

2 Protocols
Compounded Minoxidil Application (82M/82F)
Alan Bauman- Part the hair to expose the scalp.
- Place the applicator tip of the bottle directly onto the scalp.
- Apply the solution directly to the scalp, avoiding hair.
- Repeat this process twice daily, every day, taking approximately 90 seconds per application.
Bauman's Proprietary Platelet-Rich Plasma (PRP) Protocol
Alan Bauman- Draw 60 cc's of the patient's blood.
- Perform a bedside CBC on the whole blood using a Coulter counter to determine initial platelet count.
- Conduct a dual-spin centrifugation process: The first gentle spin removes red blood cells (aiming for <1% hematocrit). The second spin concentrates platelets and monocytes.
- Measure the final platelet count of the concentrated PRP to ensure it meets target concentrations (e.g., 1.4-1.5 million platelets/microliter).
- Administer a complete local anesthetic block to the scalp, optionally using Pronox (nitrous oxide) for comfort during the block.
- Inject approximately 7.5 cc's of the monocyte-rich PRP into the scalp using a 27-gauge, half-inch needle, typically around 700 very tiny injections.
- Schedule follow-up treatments approximately once a year, based on individual patient response and measured outcomes.
