Common Causes Of Hair Fall In Men​

Let us look at the most common causes of hair loss in men:

  1. Genetics:

A genetic predisposition is one of the primary causes of hair loss in men. If it runs in your family, then you are more likely to have it. Androgenetic alopecia, [1] or male pattern baldness, may start as early as your teens, depending on your family history.

  1. Hormonal Changes:

Your hormones also have a role to play when it comes to hair loss. DHT [2] (dihydrotestosterone), an androgen, causes your hair follicles to shrink, which ultimately leads to hair thinning and hair loss.

  1. Age:

Hair loss can be a sign of ageing. As you age, your hair growth will become slower, and the density will decrease. Most men notice male pattern baldness as they age.

  1. Medical Conditions:

Specific medical illnesses can lead to temporary or permanent hair loss. Autoimmune disorders, such as alopecia areata, lupus, or thyroiditis, attack the healthy hair follicles, causing them to fall out.

  1. Nutritional Deficiencies:

Your diet is one of the common causes of hair fall in men. Consuming a diet lacking in essential vitamins, protein, and minerals can cause excessive hair shedding in men.

  1. Medication Side Effects:

Sometimes, hair loss can be a side effect of the medication you take. Steroids and certain drugs used to treat conditions, like blood pressure, acne, cholesterol, depression, and anxiety, can cause hair thinning in men.

  1. Unhealthy Lifestyle Habits:

An unhealthy lifestyle is one of the significant causes of hair fall in men. Consuming too much alcohol, smoking, and inadequate sleep can affect your hair health.

  1. Stress:

Excessive stress (physical or emotional) can trigger hair loss in men. Although temporary, stressful events like sudden weight loss, losing a loved one, or surgery may contribute to telogen effluvium. [3]

Common Symptoms Of Hair Loss In Men

Hair loss can manifest in several forms, depending on the cause. Watch out for the following signs and symptoms that will help you identify if it is normal or a serious concern that should be addressed immediately:

  1. Gradual Thinning on the Crown: This is one of the most common symptoms often noticed in men as they age. Your hair starts to gradually thin at the top of your head, which will eventually lead to baldness.
  2. Receding Hairline: One of the most common types of hair loss is where you notice a receding hairline on the forehead.
  3. Hair loss at the Temples: Male pattern baldness causes hair loss at your temples, making your hairline [4] appear like the shape of M.
  4. Bald Patches: You may notice circular or patchy bald spots on your scalp, which is a sign of alopecia areata.
  5. Sudden Hair Loss: You may see clumps of hair coming out when you comb or shampoo your hair. This is generally a sign of stress, nutritional deficiency, a medical illness, or side effects from medication.

When To Visit A Dermatologist?

While it is normal to lose 50 to 100 strands per day, anything beyond that is concerning. When you see signs of hair thinning, receding hairline, bald patches or sudden hair loss, talk to a dermatologist immediately. These could be indications that you need medical intervention to treat the condition.

How Will A Dermatologist Diagnose Hair Fall?

Early diagnosis can help treat hair loss effectively. Dermatologists at Oliva diagnose and identify the root cause of hair loss, and suggest a customised treatment plan to address the concern effectively. During your consultation with our dermatologist, they will perform a trichoscan to analyse your hair and scalp condition. They will inquire about your medical history, lifestyle habits and check if hair loss runs in your family. Additionally, you may also be asked to undergo some medical tests to check for any nutritional deficiencies or hormonal disorders. These details will help them pinpoint the underlying cause of hair loss.

Best Treatments For Hair Loss For Men

Depending on the type and severity of hair loss, our dermatologists at Oliva may recommend the following treatments as standalone or in combination.

  1. PRP Treatment: Platelet-Rich Plasma (PRP) therapy is an advanced hair loss treatment in which doctors inject activated growth factors into the affected areas of the scalp. This stimulates dormant hair follicles and promotes natural hair regrowth. Dermatologists may recommend this treatment if you have androgenetic alopecia and use the US FDA-approved centrifuge technology. This is a safe treatment as it uses your own blood.
  2. Hair Threads: This non-surgical hair loss treatment involves inserting biodegradable PDO threads into your scalp to strengthen weak hair follicles and stimulate hair growth. If you are experiencing early to moderate stages of hair loss, this treatment is suitable for you.
  3. QR678 Neo: This revolutionary hair loss treatment involves injecting a natural growth factor solution directly into the areas of the scalp that are affected by hair loss. This revives inactive hair follicles and encourages natural hair regrowth. QR678 treatment is ideal for individuals experiencing male pattern baldness, hair thinning or hair loss due to nutritional deficiency.
  4. Hair Transplant: This is the most effective method for regrowing hair in bald areas of the scalp. Doctors extract hair follicles from the donor areas and insert them carefully into the thinning or bald areas of your scalp. This gives natural-looking hair and a hairline. It is a permanent hair restoration treatment that leaves no visible scars on your scalp.
  5. Oral Medications: You may be given oral medications, like nutrient supplements or medicines related to the diagnosed underlying issues.
  6. Topical Medications: You may also be given topical medications, such as minoxidil, to reduce hair fall and strengthen your hair.
