Why is my hair falling out?

If you’ve noticed more hair in the shower, on your pillow, or in your brush, you’re not alone. Hair shedding can feel alarming, but understanding what’s actually happening is the first step toward fixing it.

The truth is, hair loss is rarely caused by just one thing. It’s usually a combination of internal factors that disrupt the hair growth cycle. This is why supporting the body from within can make a real difference, and why many people turn to a hair growth supplement like our Hair Revival Complex to support healthier hair from the inside out.

This article breaks down the most common reasons hair falls out, what’s happening inside your body, and what you can do to support healthier hair growth.

Hair Loss Is Usually Not One Single Problem

Hair doesn’t fall out randomly. Your follicles respond to what’s happening inside your body. Hormones, stress, inflammation, nutrient availability, and even gut health all influence the hair cycle.

When one or more of these systems is out of balance, hair growth slows and shedding increases.

This is why quick fixes like surface-level products alone often don’t deliver lasting results. Hair growth depends on what’s happening internally.

The Main Reasons Hair Falls Out

Hormonal Changes

Hormones play a major role in hair growth. Shifts in hormones can shorten the growth phase of the hair cycle, leading to increased shedding. For example, changes in androgens (including DHT) can affect follicle sensitivity and reduce hair thickness over time.

Hormonal fluctuations can be triggered by:

• Stress
• Age
• Hormonal cycles
• Lifestyle changes

When hormones fluctuate, the hair growth cycle can be disrupted.

Stress and Cortisol

Stress isn’t just emotional; it has a physical effect on the body. When stress hormones rise, the body prioritises essential systems over non-essential ones like hair growth.

High cortisol levels can push more hair follicles into the resting (shedding) phase. This is why many people notice increased hair fall during periods of chronic stress, illness, or burnout.

Nutrient Deficiencies

Hair growth requires specific nutrients to function properly. If your body doesn’t have what it needs, hair becomes weaker, thinner, and slower to regrow.

Common nutrient gaps linked to hair issues include:

• Protein and amino acids
• Iron and supporting nutrients
• B vitamins
• Zinc and trace minerals

Without enough raw materials, the body simply can’t build strong hair.

Inflammation in the Body

Inflammation can disrupt normal hair growth by affecting the scalp, follicles, and internal systems. When the body is in a constant inflammatory state, it diverts resources away from non-essential functions like hair growth.

Sources of inflammation can include:

• Poor diet
• Gut imbalance
• Stress
• Environmental factors

Reducing internal inflammation helps create a better environment for hair to grow.

Gut Health and Absorption

Your gut plays a huge role in nutrient absorption. If your gut isn’t functioning well, you may not absorb the nutrients your hair needs, even if you’re eating well or taking supplements.

Poor gut health can lead to:

• Nutrient deficiencies
• Increased inflammation
• Hormonal imbalances

All of these can affect hair health.

What Can You Do?

Because hair loss is usually multi-factorial, the most effective approach is to support the internal systems that influence hair growth.

Helpful steps include:

• Supporting hormone balance
• Managing stress and cortisol
• Improving nutrient intake
• Supporting gut health
• Reducing inflammation

When these areas are supported, the hair growth cycle has a better chance of stabilising.

Supporting Your Hair From the Inside

Hair grows from within. Supporting the body systems that influence hair growth is one of the most effective ways to reduce shedding and support healthier regrowth.
