Alopecia: What it is, Causes, Symptoms, Treatment & More

What is Alopecia?

Alopecia refers to a broad category of hair disorders that lead to temporary or permanent hair shedding. It can occur gradually or suddenly, depending on the condition. Hair loss may be temporary or permanent and can affect people of any age or gender. The condition may result from genetics, autoimmune disorders, hormonal changes, medications, or underlying health conditions. Treatment depends on the cause and severity of hair loss.

How Common is Alopecia?

Hair loss is a growing concern in India, particularly among young men. According to a study analysing the hair health of over 5.3 lakh Indian men, nearly 60% of men under 25 reported hair loss. The study also found that 30% of young men experienced hair loss linked to irregular sleep patterns. Additionally, 37% of participants attributed their hair loss to poor gut health, suggesting that digestive well-being may play an important role in hair growth.

What are the Symptoms of Alopecia?

Different types of Alopecia have varying symptoms. Some of the symptoms and warning signs of Alopecia that may appear include:

• Patchy Hair Loss: Round or oval patches of hair loss may appear on the scalp, beard, eyebrows, eyelashes, or other parts of the body.

• Nail Pitting (Only in case of Autoimmune Alopecia): Small dents, ridges, or pits may develop on the fingernails or toenails.

• Itching or Burning: Some people may experience mild itching, tingling, or burning sensations before hair loss occurs.

• Skin Colour Changes: The affected areas may appear red, purple, brown, or grey in rare cases.

• Visible Hair Follicle Openings: Tiny follicle openings (follicular ostia) may remain visible in the bald patches.

• Black Dots on the Scalp: Broken hair shafts may appear as black dots within the affected hair follicles.

• Exclamation Mark Hairs: Short hairs that are narrower near the scalp and thicker at the tip may develop around bald patches.

• White Hair Regrowth: Hair that grows back after hair loss may initially appear white or grey before regaining its natural colour.

What are the Types of Alopecia?

Alopecia is not a single condition but a generic medical term for any type of hair loss. These are the most common types of alopecia:

• Androgenetic Alopecia: Most common type, known as Hereditary male or female pattern baldness. It is caused by genetics or hormones.

• Alopecia Areata: This is an autoimmune condition that causes patchy hair loss.

• Telogen Effluvium: It is a temporary type. The patient experiences widespread hair shedding triggered by intense physical or emotional stress.

• Traction Alopecia: Hair loss caused by chronic pulling from tight hairstyles.

• Anagen Effluvium: Rapid hair loss caused by medical treatments like chemotherapy.

• Cicatricial (Scarring) Alopecia: A rare inflammatory disorder that permanently destroys hair follicles.

What Causes Alopecia?

Alopecia develops mainly due to the following:

• Family History (Genetics): Hereditary hair loss, called androgenetic alopecia, is the most common cause and usually develops slowly as people get older.

• Hormonal Changes: Pregnancy, childbirth, menopause, and thyroid problems can cause hair loss that may be temporary or permanent.

• Autoimmune Conditions: Autoimmune disorder is the cause of a specific type of alopecia, called Alopecia Areata.This is caused when the immune system attacks hair follicles leading to patchy hair loss.

• Radiation Therapy: Radiation treatment to the head can harm hair follicles and affect hair growth in the future.

• Physical or Emotional Stress: Serious illness, surgery, losing a lot of weight, or emotional trauma can cause temporary hair shedding.

• Nutritional Deficiencies: Not getting enough iron, zinc, vitamin D, protein, or other important nutrients can lead to hair thinning and shedding.

• Ageing: As people get older, hair growth can slow down and hair may become thinner.

What are the Complications of Alopecia?

These are the most common complications of alopecia:

• Emotional Distress and Anxiety: Hair loss can change how people see themselves and may cause stress, worry, or embarrassment.

• Depression and Low Self-Esteem: Losing a lot of hair can lower a person’s confidence and, for some, lead to depression.

• Social Withdrawal: Some people with alopecia might avoid social events because they feel self-conscious about how they look.

• Increased Risk of Sunburn: When scalp hair is lost, the skin is more exposed to the sun’s UV rays, which raises the risk of sunburn.

• Scalp Irritation: Without hair, the scalp can become more sensitive to things like weather, which may cause dryness, irritation, or discomfort.

• Permanent Hair Loss: Alopecia can damage hair follicles so much that hair loss becomes permanent.

• Reduced Quality of Life: Worries about appearance from hair loss can impact relationships, work, and overall happiness.

When Should I See My Healthcare Provider?

It is normal to lose some hair, but if you notice sudden hair loss, it could be a sign of a health problem. Talk to your doctor if you experience any of the following:

• Notice sudden or heavy hair loss, especially if it occurs quickly or worsens rapidly.

• See bald spots appear, especially if they show up suddenly or keep getting bigger.

• Have an itchy, red, or painful scalp, as these symptoms may indicate an infection or another scalp problem.

• Notice hair loss along with feeling tired or having unexplained weight changes, as this could point to another health issue.

• See hair loss after starting a new medication, since some medicines can cause temporary or ongoing shedding.

How is Alopecia Diagnosed?

Doctors find out if someone has alopecia by looking at their medical history, doing a physical exam, and using special tests.

How is Alopecia Managed?

Alopecia can be managed through several treatment approaches such as:

• Corticosteroids: Anti-inflammatory medications like corticosteroids help suppress the immune response in autoimmune diseases and may be given as injections, tablets, or topical applications.

• Minoxidil: A topical medication that can help stimulate hair growth and slow hair loss, including pattern baldness.

• Phototherapy: Controlled exposure to ultraviolet (UV) light may help promote hair regrowth in some people with alopecia.

• Platelet-Rich Plasma (PRP) Therapy: This treatment involves injecting concentrated platelets from your own blood into the scalp to encourage hair follicle activity and hair growth.

• Topical Immunotherapy: Special medications are applied to the scalp to trigger an immune response that may stimulate hair regrowth.

• Hair Transplant Surgery: In suitable cases, healthy hair follicles are moved from one part of the scalp to areas affected by hair loss.

• Styling Techniques and Hair Prosthetics: Wigs, hairpieces, hair fibres, and certain hairstyles can help conceal hair loss and improve appearance.

• Lifestyle Modifications: Making some lifestyle changes, like managing stress, eating a balanced diet, and treating any medical conditions, can help keep your hair healthy and improve treatment results.

Alopecia During Pregnancy

It is normal for hair to change during pregnancy due to hormonal shifts. Many women find their hair gets thicker and fuller during pregnancy due to hormonal changes. However, after childbirth, it is common to experience increased hair shedding for several months.

This postpartum hair loss is temporary and usually goes away in a few months. Here are some tips for managing hair loss during pregnancy:

• Eat foods that are rich in nutrients.

• Take prenatal vitamins as your doctor recommends.

• Avoid using harsh treatments on your hair.

• Find ways to manage your stress.

• Talk to your doctor before using any medications for hair loss.

What is the Prognosis for Alopecia?

The outlook for alopecia depends on what is causing it and the type of hair loss. Often, hair loss gets better when the main trigger is found and treated. Hair can grow back on its own or with treatment, but sometimes it may return. Getting diagnosed early and starting the right treatment can help slow down hair loss, encourage regrowth, and keep the hair you have.

Can Alopecia Be Reversed?

Yes, alopecia can be reversed, especially when it is caused by stress, a lack of nutrients, changes in hormones, or some illnesses. Often, the hair follicles stay healthy, so hair can grow back after the main cause is treated. Early diagnosis and the right treatment can help hair regrow and keep your existing hair.

How Can I Prevent Alopecia?

Listed below are the steps that can help you lower the chances of developing alopecia:

• Maintain a healthy diet rich in vitamins and minerals to support healthy hair growth and follicle function.

• Manage stress effectively by practising relaxation techniques and adopting healthy coping strategies.

• Avoid tight hairstyles that pull on the hair and scalp, such as braids or ponytails.

• Limit heat styling and chemical treatments to reduce hair damage and breakage over time.

• Treat scalp infections quickly to prevent inflammation and keep your hair follicles healthy.

• Try not to smoke, since it can affect your blood flow and may lead to hair thinning.

• Maintain a healthy lifestyle by exercising often, sleeping well, and building habits that help you feel your best.

Does Health Insurance Cover Alopecia?

In most cases, health insurance plans in India do not cover alopecia treatments or hair transplant procedures when they are performed for cosmetic or aesthetic reasons. Since hair loss is generally not considered a life-threatening medical condition, expenses related to consultations, medications, hair restoration therapies, and hair transplants are usually paid out of pocket.

However, coverage may be available under health insurance if hair loss occurs as a result of an underlying medical condition, accident, burns, or certain medical treatments, depending on the insurer and policy terms.
