Top 9 Causes of Hair Loss

Many people contend with hair loss at some point in their life. Learning about the different causes of hair loss can help a person manage it and plan next steps. Let’s take a look at a few of the top reasons people can lose their hair.

Common Causes of Hair Loss

1. Genetics (Androgenetic Alopecia)
   The most common cause of hair loss is genetics. Hereditary hair loss, also known as androgenetic alopecia, affects both men and women, is commonly referred to as “male (or female) pattern baldness,” and is characterized by a gradual thinning of hair over time.
2. Hormonal Changes
   Hormonal imbalances – such as those caused by pregnancy, menopause, thyroid disorders, or polycystic ovary syndrome (PCOS) – can lead to temporary or permanent hair loss.
3. Stress
   Emotional or physical stress can trigger a condition called telogen effluvium, where hair prematurely enters the resting phase of the hair growth cycle – resulting in sudden shedding. This cause is generally temporary, and hair should resume growing several months after the source of stress is removed.
4. Nutritional Deficiencies
   A lack of essential nutrients like iron, vitamin D, and biotin can weaken hair, leading to thinning and breakage. A balanced diet is crucial for maintaining healthy hair.
5. Medical Conditions 
   Certain medical conditions (such as scalp infections and autoimmune diseases like alopecia areata) can cause hair loss.
6. Medications
   Some medications – including those to treat cancer, arthritis, depression, and high blood pressure – may contribute to hair loss.
7. Heat and/or Chemical Damage
   Frequent use of heat styling tools and chemical treatments, such as hair straighteners can damage the hair shaft and, sometimes, the hair follicle.
8. Traction Alopecia
   Tight hairstyles (like ponytails, buns, or braids) can cause traction alopecia – a form of hair loss resulting from consistent pulling of or stress on the scalp. Frequently wearing very tight headwear, like a tight baseball caps, helmets, etc., can do the same.
9. Age
   It catches up with us all eventually. As they age, most people notice thinning or a loss of hair. At some point, follicles just stop producing hair. Hair also eventually loses its color, graying or becoming white. And while frontal fibrosis hair loss is frequently attributed to aging, the cause may actually have several factors such as menopause, genetics, or autoimmune conditions.

How Do I Know What Type of Hair Loss I Have?

Identifying the type of hair loss that you are experiencing often depends on its pattern and cause. If your hair is thinning gradually in certain areas (like the crown or hairline), it could be hereditary. If you experience sudden hair shedding in large amounts, it may be stress-related or linked to a medical condition.

Consulting with a dermatologist or a trichologist can help determine the specific cause and recommend treatment.

What Hair Type Loses the Most Hair?

All hair types can experience hair loss, but people with fine hair may notice thinning more easily because each strand is smaller in diameter. Curly or textured hair types may appear fuller even if hair loss occurs because the curls create the appearance of volume. However, the amount of hair lost is generally consistent across different hair types.

How Do I Know If My Hair Loss Is Normal?

It is normal to lose about 50-100 hairs per day. If you notice excessive shedding or bald patches, it may indicate a problem. Sudden unexplained hair loss or large clumps of hair falling out may require medical attention.

Can You Reverse Hereditary Hair Loss?

While there is no cure for hereditary hair loss, treatments like minoxidil (Rogaine®) and finasteride (Propecia®) can help slow down the process and promote new growth in some cases. Here at PNW Hair Restoration, we offer a special compounded combination of minoxidil and finasteride that is very effective. Early intervention is key with topicals, though, so it’s important to start treatment as soon as you notice thinning.

Understanding the cause of your hair loss can help you take the right steps toward maintaining healthy hair. If you are unsure about the severity of your hair loss, consult a healthcare professional for personalized advice.
