Stress-Related Hair Loss: How Functional Keratin™ Can Help Rebuild What Stress Takes Away

February 20, 2023|Natalie Harrison

Stress is part of life. Work deadlines, family responsibilities, financial worries, relationships, unexpected challenges, it all adds up. And while your body is designed to handle short-term stress, chronic stress takes a serious toll on your physical and mental health.

One of the most visible signs of chronic stress? Hair loss.

If you've noticed more hair in your brush, thinner ponytails, or a widening part, stress might be the culprit. The good news is that stress-related hair loss is often reversible, especially when you support your body with the right nutrients, including Functional Keratin™.

Let's dive into how stress causes hair loss, what you can do about it, and how Functional Keratin™ can help rebuild what stress takes away.

How Stress Causes Hair Loss: The Science

Your hair grows in a continuous cycle with three main phases:

Anagen (Growth Phase)

This is the active growth phase, lasting 2-7 years. About 85-90% of your hair is in this phase at any given time.

Catagen (Transition Phase)

A short transition phase lasting 2-3 weeks, where growth stops and the hair follicle shrinks.

Telogen (Rest Phase)

A resting phase lasting about 3 months, after which the hair sheds naturally. About 10-15% of your hair is in this phase at any time.

Under normal conditions, this cycle continues seamlessly. Old hairs fall out, and new hairs grow in. You lose 50-100 hairs per day naturally without noticing significant thinning.

But when you experience chronic stress, this cycle gets disrupted.

What Chronic Stress Does to Your Hair

When you're stressed, your body releases cortisol, the primary stress hormone. Cortisol is essential for short-term stress response, but when cortisol remains elevated chronically, it wreaks havoc on your body, including your hair.

Here's what happens:

1. Accelerated Transition to Telogen Phase

Chronic stress pushes a disproportionate number of hair follicles from the growth phase (anagen) into the resting phase (telogen) prematurely. This means more hairs enter the shedding phase simultaneously.

This condition is called telogen effluvium, a temporary but noticeable form of hair loss triggered by physical or emotional stress.

2. Slowed Hair Growth Cycle

Stress slows down your hair's natural growth cycle. Even the hairs that remain in the growth phase grow more slowly, resulting in hair that appears thinner, shorter, and less vibrant.

3. Nutrient Depletion

Cortisol actively depletes essential nutrients, including:

Protein: Needed to produce keratin
B vitamins (especially biotin): Essential for keratin synthesis
Zinc and iron: Critical for hair follicle health
Magnesium: Supports cellular energy production

Without these nutrients, your body can't produce strong, healthy hair, even if follicles are in the growth phase.

4. Reduced Blood Flow to Follicles

Chronic stress constricts blood vessels, reducing circulation to your scalp. Hair follicles rely on nutrient-rich blood to support growth. Poor circulation means weak, undernourished follicles.

5. Increased Inflammation

Stress triggers systemic inflammation, which can damage hair follicles and disrupt the hair growth cycle further.

The result? Noticeable hair thinning, increased shedding, and hair that looks dull and lifeless.

Here's something important to understand: stress-related hair loss doesn't happen immediately.

The hair cycle takes time. When a stressful event or period pushes hair follicles into telogen phase, those hairs don't fall out for about 2-3 months.

This delayed timeline means you might not connect your hair loss to a stressful period that happened months earlier. But the connection is real.

The good news? Because telogen effluvium is triggered by a specific stressor, it's usually temporary. Once the stress is managed and your body receives the support it needs, hair growth typically resumes within 3-6 months.

How Functional Keratin™ Supports Hair Recovery From Stress

When you're experiencing stress-related hair loss, your body needs two things:

Stress reduction (so cortisol levels can normalize)
Nutritional support (to replenish what stress depletes and provide building blocks for new hair growth)

This is where Functional Keratin™ becomes essential.

What Functional Keratin™ Does

Functional Keratin™ is 91% homologous to human keratin, meaning your body recognizes it as structurally compatible and can use it immediately to:

Replenish depleted protein stores: Stress depletes the amino acids your body needs to produce keratin. Functional Keratin™ provides those exact amino acids in bioavailable form.
Trigger collagen expression: Functional Keratin™ upregulates collagen 4 and 7, which anchor hair follicles and support the dermal-epidermal junction. Stronger follicles mean less shedding.
Boost glutathione production: Functional Keratin™ is rich in cysteine, which your body uses to produce glutathione, a powerful antioxidant that helps combat oxidative stress caused by cortisol.
Support the hair growth cycle: By providing the building blocks your body needs, Functional Keratin™ helps normalize the hair cycle and support healthy growth phase duration.

Clinical Evidence

Studies show that Functional Keratin™ reduces hair loss by up to 43% when taken consistently. This isn't about masking the problem, it's about giving your body what it needs to repair and rebuild.

Why Generic Keratin Doesn't Work

Most keratin supplements use hydrolyzed keratin, which is chemically broken down into tiny fragments. Your body struggles to recognize and use these fragments effectively.

Functional Keratin™ retains its long-chain protein structure through gentle extraction, making it immediately usable by your body. This is why it delivers measurable results where generic keratin fails.

Supporting Nutrients That Work With Functional Keratin™

While Functional Keratin™ is essential, it works best when paired with other supportive nutrients. This is why KiriGlow combines:

Biotin (Vitamin B7)

Facilitates keratin synthesis at the metabolic level
Supports hair follicle health
Often depleted by chronic stress

Zinc

Essential for hair tissue growth and repair
Supports immune function
Deficiency linked to hair loss

Vitamin C

Essential for collagen synthesis
Powerful antioxidant that combats oxidative stress
Supports iron absorption

OptiMSM™

Provides organic sulfur for disulfide bond formation
Strengthens keratin structure
Supports detoxification processes

Marine Collagen

Supports the dermis and hair follicle anchoring
Works synergistically with Functional Keratin™
Provides structural support

Together, these ingredients create a comprehensive system that supports your body's recovery from stress-related hair loss.

Stress Management: Essential for Hair Recovery

Supplementing with Functional Keratin™ is critical, but you also need to address the root cause: stress itself.

Here are evidence-based strategies for managing chronic stress:

1. Prioritize Sleep

Sleep is when your body repairs and regenerates. Aim for 7-9 hours of quality sleep per night.

Establish a consistent sleep schedule
Create a calming bedtime routine
Limit screen time before bed
Keep your bedroom cool, dark, and quiet

2. Move Your Body

Physical activity reduces cortisol and releases endorphins, the body's natural stress relievers.

Walk, run, swim, cycle, whatever you enjoy
Aim for at least 30 minutes most days
Include strength training and stretching
Find activities that feel restorative, not punishing

3. Practice Mindfulness and Relaxation

Mindfulness practices directly reduce cortisol levels and support nervous system regulation.

Meditation or guided relaxation
Deep breathing exercises
Yoga or tai chi
Journaling
Spending time in nature

4. Set Boundaries

Chronic stress often comes from overcommitment. It's okay to say no.

Delegate when possible
Set realistic expectations for yourself
Protect your time and energy
Ask for help when you need it

5. Seek Support

Talking to someone can make a huge difference.

Friends and family
Therapist or counselor
Support groups
Online communities

6. Nourish Your Body

Stress depletes nutrients. Support your body with:

Protein-rich foods (eggs, fish, poultry, legumes)
Leafy greens and colorful vegetables
Healthy fats (nuts, seeds, avocado, olive oil)
Whole grains
Plenty of water

Frequently Asked Questions

Chronic stress elevates cortisol, which disrupts the hair growth cycle by pushing follicles prematurely from the growth phase (anagen) into the resting phase (telogen). This condition, called telogen effluvium, causes more hairs to shed simultaneously. Stress also depletes essential nutrients (protein, biotin, zinc, iron), reduces blood flow to follicles, and increases inflammation, all of which contribute to hair loss.

Hair follicles don't shed immediately when pushed into telogen phase. It takes about 2-3 months for those hairs to fall out. This delayed timeline means the hair loss you're experiencing today likely relates to a stressful period 2-3 months ago. Understanding this timeline helps you identify triggers and take action.

No. Telogen effluvium caused by stress is usually temporary. Once stress is managed and your body receives adequate nutritional support (like Functional Keratin™), hair growth typically resumes within 3-6 months. However, if stress remains chronic and unmanaged, hair loss can persist.

Functional Keratin™ provides the amino acid building blocks your body needs to produce strong keratin, which stress depletes. It's 91% homologous to human keratin, so your body can use it immediately to rebuild hair structure. It also triggers collagen expression (supporting follicle anchoring) and boosts glutathione production (combating oxidative stress). Clinical studies show it reduces hair loss by up to 43%.

Most people notice reduced shedding within 3 months of consistent use. Visible new growth (baby hairs) typically appears by 3-6 months. The most dramatic results occur after 6 months onwards. Remember, hair growth is slow, so patience and consistency matter more than speed.

Absolutely. In fact, chronic stress is one of the most important times to supplement with Functional Keratin™. Stress depletes the nutrients your body needs to produce keratin. Supplementation replenishes those stores and supports your body's ability to maintain hair health despite stress. Pairing supplementation with stress management practices delivers the best results.

Functional Keratin™ provides essential nutritional support, but if cortisol remains chronically elevated, it will continue to disrupt your hair cycle and deplete nutrients. For best results, combine Functional Keratin™ supplementation with stress management practices like sleep, movement, mindfulness, and setting boundaries. Addressing both the cause (stress) and the effect (nutrient depletion) is most effective.

Biotin facilitates keratin synthesis. Zinc supports hair follicle health and immune function. Vitamin C supports collagen synthesis and combats oxidative stress. OptiMSM™ provides sulfur for disulfide bond formation. Marine collagen supports follicle anchoring. Iron supports oxygen transport to follicles. KiriGlow combines all of these with Functional Keratin™ for comprehensive support.

While telogen effluvium is temporary, prolonged chronic stress can impact hair follicle health long-term. Some people notice changes in hair texture, thickness, or growth pattern after periods of extreme or prolonged stress. Early intervention with stress management and Functional Keratin™ supplementation helps minimize long-term impacts.

If your stress is managed and cortisol levels remain normal, your hair should maintain its health. However, if you experience another period of chronic stress, hair loss could return because stress will again deplete nutrients and disrupt the hair cycle. Many people continue supplementing with Functional Keratin™ as preventive support, especially during high-stress periods.
