The Truth About Hair Loss: What’s Actually Happing Beneath the Surface

The Hair Growth Cycle (and where things go wrong)

Every hair on your head is in one of four phases or I like to think about this in seasons:

1. Anagen (Growth Phase) Mid Summer and/or Early Spring

• Lasts 2–7 years

• Hair is actively growing from the follicle

• ~85–90% of your hair should be here

2. Catagen (Transition Phase) Fall and/or Late Spring

• Lasts ~2–3 weeks

• Follicle shrinks and detaches from blood supply

3. Telogen (Resting Phase) Winter

• Lasts ~2–4 months

• Hair sits idle, not growing

4. Exogen (Shedding Phase) End of Summer and/or Mid Spring

• Hair releases and falls out

• New hair begins pushing through underneath

👉 Healthy cycle = staggered timing👉 Hair loss = too many hairs shift into telogen/exogen at once

What Happens in the Follicle During Sudden Hair Loss

When someone says, “My hair is falling out like crazy all of a sudden”, they’re usually experiencing Telogen Effluvium.

Here’s what’s happening biologically:

• A stressor hits the body (hormonal, emotional, metabolic, inflammatory)

• The follicle prematurely exits anagen phase

• Blood flow + nutrient signaling to the follicle drops

• The bulb shrinks and detaches earlier than it should

• Hair shifts into telogen → then sheds 6–12 weeks later

💡 Important:The shedding you see today is usually a delayed reaction to something that happened 2–3 months ago

Why Hair Loss Is Happening More Now

This isn’t random—there’s a clear pattern in modern life:

1. Hormonal Dysregulation

• Birth control cycling on/off

• Perimenopause shifts (even in early 40s)

• Thyroid imbalances

• Low progesterone / high estrogen dominance

👉 Hair follicles are extremely hormone-sensitive

2. Chronic Stress & Nervous System Overload

• High cortisol shortens anagen phase

• Blood flow gets diverted away from “non-essential” systems like hair

👉 Your body prioritizes survival over hair growth

3. Rapid Weight Loss / GLP-1 Medications

• Seen heavily right now with drugs like Ozempic

• Sudden calorie restriction = nutrient depletion

• Protein deficiency = weak keratin production

4. Inflammation & Gut Health Issues

• Poor absorption of iron, zinc, biotin

• Leaky gut → systemic inflammation

• Immune system can start targeting follicles

5. Overprocessing & Mechanical Damage

• Bleach, tension, extensions

• Heat damage + scalp inflammation

👉 This is more breakage, but often overlaps with shedding

6. Environmental & Lifestyle Factors

• Poor sleep

• Toxins

• Overtraining without recovery

The Different Types of Hair Loss You’ll See

• Telogen Effluvium → sudden shedding

• Androgenetic Alopecia → thinning over time (hormone-driven)

• Alopecia Areata → patchy loss

  
  

How to Restore Hair Growth

(Ranked from natural → aggressive treatment)

Level 1: Foundational / Natural (Start Here)

These rebuild the environment for hair to grow again:

• Protein intake (minimum ~100g/day for most women)

• Iron, zinc, biotin, B vitamins

• Scalp massage (increases blood flow)

• Rosemary oil (shown to rival minoxidil in some studies)

• Red light therapy

👉 This stage is about turning growth signals back on

Level 2: Targeted Support

• Peptides (like GHK-Cu for regeneration)

• Collagen supplementation

• Adaptogens (to regulate cortisol)

• Hormone balancing (progesterone, thyroid support if needed)

👉 This is where you correct internal imbalances

Level 3: Clinical Topicals

Hair growing back after Alopecia Areata

• Minoxidil

  • Increases blood flow to follicles

  • Extends anagen phase

  • Can cause initial shedding (normal)

👉 Works well but requires consistency

Level 4: Medical & Regenerative Treatments

• PRP (Platelet-Rich Plasma injections)

• Microneedling/stamping scalp therapy

• Prescription hormone blockers (for androgen-related loss)

👉 These stimulate follicles more aggressively

Level 5: Advanced / Aggressive

• Hair transplants

• Oral medications (strong hormone modulators)

👉 Used when follicles are miniaturized long-term

The Most Important Truth

Hair loss is rarely the real problem.

It’s a symptom of:

• stress

• hormone shifts

• nutrient depletion

• nervous system overload

When you fix the internal environment, the follicle often recovers on its own—because it’s not dead, it’s just been told to “pause.”

If You’re Noticing Shedding Right Now

Anchor this:

• What changed 2–3 months ago?

• Food? Stress? Hormones? Weight? Medications?

That’s your root.

Hair loss can feel sudden, emotional, and out of your control—but biologically, it’s rarely random. Your hair is always responding to the internal environment you’ve created over time. When something shifts—stress, hormones, nutrition, inflammation—the follicle listens.

The important part is this: most of the time, the follicle isn’t gone—it’s paused.

When you understand the cycle, identify the root cause, and support the body instead of just chasing the symptom, growth can come back. Not overnight, and not always in the exact way you expect—but steadily, predictably, and with intention.

Healthy hair isn’t built from a single product. It’s built from consistency, regulation, and giving your body enough safety and resources to prioritize growth again.

And when that happens, the hair follows.
