What is the Reason for Hair Falling?

Hair fall is something nearly all of us experience at some point, whether it’s finding a few strands on the pillow or noticing more in the shower drain. While a certain amount of shedding is perfectly normal, excessive hair loss can be distressing and leave many wondering what’s going wrong.

Understanding why hair fall happens, what can be done about it, and whether hair can truly grow back is essential for managing expectations and choosing the right approach. There’s no one-size-fits-all solution — but there are answers.

We’ll explore the most common reasons behind hair loss, look at whether regrowth is possible, and share practical, effective tips to help stop further shedding. Let’s take the guesswork out of hair care.

1. What is the Reason for Hair Falling?

Natural Hair Shedding vs. Hair Loss

It’s completely natural to lose some hair each day. In fact, shedding around 50 to 100 hairs daily is considered normal and part of the body’s regular hair growth cycle. This cycle consists of three main phases:

• Anagen – the growth phase
• Catagen – the transitional phase
• Telogen – the resting and shedding phase

Hair is constantly cycling through these stages, so noticing a bit of hair on your brush or in the shower isn’t usually cause for concern. However, when hair starts falling out more than usual or thinning becomes visible, it may point to an underlying issue.

Common Causes of Excessive Hair Fall

Several factors can contribute to noticeable hair loss, and identifying the root cause is key to finding the right solution. Here are some of the most common:

Genetics (Androgenetic Alopecia)

This is the most widespread cause of hair loss in both men and women. Often referred to as male or female pattern baldness, it’s hereditary and typically progresses gradually over time.

Hormonal Imbalances

Fluctuations in hormones can have a direct impact on hair growth. Conditions like thyroid disorders, polycystic ovary syndrome (PCOS), postpartum changes, and menopause can all lead to increased shedding or thinning.

Nutritional Deficiencies

A lack of essential nutrients — particularly iron, zinc, protein, vitamin D, and biotin — can weaken hair structure and reduce growth. Poor diet or absorption issues can both play a role here.

Stress and Anxiety

High levels of emotional or physical stress can trigger a condition known as telogen effluvium, where a large number of hairs shift into the shedding phase at once. This usually occurs a few weeks or months after the stressful event.

Hair Care Practices

Frequent heat styling, chemical treatments, tight hairstyles (like braids or ponytails), and over-washing can all damage the hair shaft and lead to breakage or fallout over time.

Medical Conditions

Autoimmune disorders such as Alopecia Areata can cause sudden, patchy hair loss. Fungal infections and other scalp conditions may also interfere with healthy hair growth.

Medications and Treatments

Certain medicines — including chemotherapy drugs, some antidepressants, and blood pressure medications — list hair loss as a potential side effect. In many cases, the hair may regrow once treatment ends.

2. Can Hair Regrow?

One of the most common questions people ask when experiencing hair loss is: “Will it grow back?” The good news is that in many cases, yes — hair can regrow. But it often depends on the cause and how early it’s addressed.

When Hair Regrowth Is Possible

Hair regrowth is absolutely achievable in several situations, especially when the underlying cause is temporary or treatable. For example:

• Telogen effluvium, often triggered by stress, illness, or surgery, usually resolves on its own within a few months once the body returns to balance.
• Postpartum hair loss, common after childbirth, is typically temporary and improves within a year.
• Nutritional deficiencies or hormonal imbalances can also lead to hair fall — but with the right diet, supplements, or medical treatment, hair often begins to grow back.

When Regrowth Is Challenging

In some cases, regrowth is more difficult — particularly if the hair follicles have been permanently damaged.

• Scarring alopecia (cicatricial alopecia), where inflammation destroys hair follicles, can lead to irreversible hair loss.
• Long-standing pattern baldness (androgenetic alopecia) may also result in dormant or miniaturised follicles that no longer produce visible hair.

That said, early intervention can often help slow progression and support regrowth in areas that haven’t been permanently affected.

Options for Encouraging Regrowth

If you’re hoping to stimulate hair growth, there are several approaches worth considering:

Topical Treatments

• Minoxidil (available over-the-counter) is clinically proven to promote hair growth.
• Natural oils like rosemary, peppermint, and castor oil may help improve scalp circulation and stimulate follicles.

Oral Supplements

• Nutrients such as biotin, collagen, iron, and vitamin D support healthy hair from the inside out — but always seek medical advice before starting new supplements.

Healthy Scalp Care

• Maintaining a clean, balanced scalp is essential. Exfoliating occasionally, keeping the scalp hydrated, and using pH-balanced products can all make a difference.

Professional Treatments

• PRP therapy (platelet-rich plasma), microneedling, and low-level laser therapy are gaining popularity and may offer results for certain types of hair loss.

Lifestyle Changes

• Managing stress, getting enough sleep, and maintaining a nutritious diet all support overall hair and scalp health. Hair is often one of the first areas affected by internal imbalances — and one of the first to improve when balance is restored.

3. How Do I Stop My Hair Fall?

If you’re noticing more hair on your pillow, in the shower, or on your hairbrush, it’s natural to want to stop it as quickly as possible. The good news is, there are practical steps you can take — but it all begins with understanding the root cause.

Diagnose the Cause

Before reaching for products or remedies, it’s vital to identify why your hair is falling out. Treating hair loss blindly can be frustrating and ineffective, so a proper diagnosis is key.

• Consult a dermatologist or trichologist who specialises in hair and scalp health.
• They may recommend blood tests to check for issues such as iron deficiency, thyroid imbalance, low vitamin D levels, or hormonal irregularities.

Once the cause is known, targeted treatment becomes much more effective.

Hair Fall Control Tips

Whether your hair loss is mild or more noticeable, these everyday habits can help support hair health and minimise shedding:

1. Gentle Hair Care Routine

• Use a sulphate-free, mild shampoo to avoid stripping your scalp of natural oils.
• Avoid over-washing, which can dry out the scalp and lead to breakage.
• Let hair air-dry when possible, and use a wide-tooth comb to prevent pulling.

2. Balanced Diet

• Make sure your meals include iron, zinc, protein, omega-3 fatty acids, and vitamin D.
• Stay hydrated — hair thrives on good internal nourishment.

3. Stress Reduction Techniques

• High stress levels can push hair into the shedding phase, so managing stress is vital.
• Try yoga, deep breathing, journalling, or regular exercise to support mental wellbeing.

4. Avoid Heat & Chemicals

• Limit the use of hair straighteners, curling tongs, and blow dryers.
• Avoid frequent bleaching, perming, or dyeing, which can weaken hair over time.

5. Scalp Massage

• Massaging the scalp for just 5 minutes a day can stimulate blood circulation and nourish the hair follicles.

6. Use of Natural Remedies

• Ingredients like onion juice, castor oil, aloe vera, and rosemary oil have been used for centuries to promote growth and strengthen roots.
• While results can vary, they’re a gentle and natural addition to your routine.

When to Seek Medical Help

While minor hair fall can often be managed at home, there are times when professional help is necessary:

• Sudden or patchy hair loss, especially if it appears overnight or in small bald spots.
• Persistent thinning, even after making lifestyle and hair care changes.
• If you suspect an underlying health condition, such as a thyroid issue, PCOS, or an autoimmune disorder.

The sooner you address the cause, the better your chances of stopping hair loss and encouraging regrowth.

Conclusion

Hair fall can feel disheartening, but it’s often your body’s way of signalling that something needs attention. The first and most important step is to identify the underlying cause — whether it’s hormonal, nutritional, stress-related, or something else entirely.

Once you understand what’s happening, you can begin taking proper, targeted care of your hair and scalp. Focus on gentle routines, balanced nutrition, stress management, and where necessary, medical support. And most importantly — stay patient. Hair regrowth takes time, and consistency is key.

If you’re unsure where to begin, don’t hesitate to consult a dermatologist or trichologist. With the right guidance and steady care, you’ll be giving your hair the best possible chance to thrive.
