Why Is My Hair Falling Out?

The Ultimate Guide to Thicker, Healthier Hair (From Root to Scalp)

Why Is My Hair Falling Out?

Quick Answer

Hair can fall out for many reasons, but the most common causes include stress, hormonal changes, nutrient deficiencies, and disruptions in the hair growth cycle. In many cases, increased shedding is temporary and linked to internal or lifestyle factors that affect how hair grows and regenerates. Supporting overall health, including nutrition, gut function, and stress levels may help promote healthier hair over time.

Quick Takeaways

Shedding 50–100 hairs per day is normal, but sudden or excessive loss may signal an underlying issue
Hair loss is often linked to stress, hormonal changes, nutrient gaps, and overall health
The gut plays an important role in absorbing nutrients needed for healthy hair growth
External factors like heat styling and harsh products can contribute to breakage
Supporting hair health often involves a combination of internal nutrition and external care
Some people choose to use targeted nutritional support to complement their routine

Understanding the Hair Growth Cycle

Hair doesn’t grow continuously. It follows a natural cycle made up of three main phases:

Anagen (growth phase): lasts 2–7 years
Catagen (transition phase): short resting period
Telogen (shedding phase): hair falls out and new hair begins to grow

When this cycle becomes disrupted, you may notice increased shedding or thinning.

According to the American Academy of Dermatology, excessive shedding often occurs when more hairs than usual enter the telogen phase at the same time.

Common Causes of Hair Loss

Hair loss isn’t usually caused by just one factor. It’s often a combination of internal and external influences.

1. Stress and Physical Changes

Periods of physical or emotional stress can trigger a condition called telogen effluvium, where hair shifts prematurely into the shedding phase.

Common triggers include:

Illness or infection
Surgery
Major life stress
Rapid weight loss

The good news is, according to the National Library of Medicine, this type of hair loss is often temporary.

2. Hormonal Changes

Hormones play a major role in hair growth and follicle function.

Hair thinning is commonly associated with:

Postpartum changes
Perimenopause and menopause
Thyroid imbalances

According to Harvard Health Publishing, hormonal shifts can shorten the growth phase and affect follicle health over time.

3. Nutrient Gaps

Hair is made primarily of keratin, a structural protein. To support this process, the body relies on a steady supply of nutrients.

Key nutrients for hair health include:

Protein
Iron
Zinc
Omega fatty acids
Biotin and B vitamins

When intake or absorption is insufficient, hair growth may be affected, according to the National Institutes of Health.

4. Gut Health and Nutrient Absorption

This is where things get especially interesting.

The gut plays a central role in overall health, including:

Nutrient absorption
Inflammation regulation
Immune signaling

Emerging research on the gut-skin axis suggests that imbalances in the gut microbiome may influence skin, and potentially hair-health.

According to research published through the National Institutes of Health (NIH), if the gut isn’t functioning optimally, the body may struggle to absorb the nutrients needed to support healthy hair growth.

5. Hair Care Practices and Damage

External factors can also contribute to breakage and thinning, including:

Frequent heat styling
Tight hairstyles (ponytails, braids)
Harsh chemical treatments
Overwashing or using irritating products

These don’t always affect the root of the hair, but they can weaken the hair shaft and lead to visible thinning over time.

Is It Hair Loss or Hair Breakage?

Not all hair loss is the same and understanding the difference can be helpful.

Shedding from the root often points to internal factors
Breakage along the strand is usually related to damage or dryness

Identifying the pattern may help guide how you approach hair care and overall support.

The Role of Diet and Internal Support

Because hair growth is a biologically active process, it requires consistent internal support.

A balanced, nutrient-dense diet may help:

Provide building blocks for keratin production
Support collagen formation
Maintain scalp and follicle health

Some individuals also choose to incorporate targeted nutritional supplements to help fill common gaps.

Formulations that include ingredients like:

Keratin peptides
Omega fatty acids
Silica
Eggshell membrane compounds

are often used to support hair structure, strength, and overall appearance.

For example, simple formulas like Silver Fern™ Brand’s Hair Complex focus on foundational nutrients for hair structure and follicle health, while more comprehensive options like Hair, Skin & Nails are designed to support multiple pathways involved in hair, skin, and nail health.*

These types of products are not intended to diagnose, treat, cure, or prevent any disease, but may complement a balanced diet and lifestyle.

How Gut Health Connects to Hair Health

Your gut and hair may seem unrelated. However, they’re more connected than they appear.

A healthy gut microbiome helps:

Break down and absorb nutrients
Support immune balance
Help regulate inflammation

When the gut is out of balance, it may influence how effectively the body utilizes nutrients important for hair growth.

This is why many wellness approaches emphasize:

Fiber intake
Prebiotic and probiotic support
Overall digestive health

as part of a broader strategy for supporting hair, skin, and overall wellness from within.

When Should You Be Concerned?

Occasional shedding is normal. However, you may want to look more closely if you notice:

Sudden or excessive hair loss
Thinning patches or widening part
Hair falling out in clumps
Shedding that lasts longer than a few months

In these cases, it’s always a good idea to consult a qualified healthcare professional for personalized guidance.

Final Thoughts

Hair loss can feel frustrating, but it is often a signal rather than a standalone issue. In many cases, it reflects a combination of internal health, nutritional status, hormonal shifts, and lifestyle factors such as stress. Instead of focusing on a single solution, a more balanced approach may include supporting overall nutrition, paying attention to gut health, being mindful of hair care habits, and considering targeted nutritional support when appropriate. Over time, these consistent habits may help support healthier hair growth and overall scalp wellness.
