A Guide to Hair Loss: Risk Factors, Diagnosis, and Prevention

How Is Hair Loss Diagnosed?

Diagnosing hair loss typically involves a combination of medical history assessment, physical examination, and diagnostic tests, which may include the following:

• Pull Test: In a pull test, a doctor gently tugs on a handful of hair to assess the shedding stage and distinguish between natural shedding and potential underlying conditions.
• Blood Test: This test identifies underlying medical conditions causing hair loss, like thyroid or autoimmune diseases. It also checks for any nutrient deficiencies contributing to hair loss.
• Scalp Biopsy: A scalp biopsy involves removing and examining a small scalp section under a microscope, usually from a hair loss area, to assess follicle health or detect underlying causes.
• Light Microscopy: Light microscopy examines hairs trimmed at their bases using a light microscope. This aids in identifying potential hair shaft disorders linked to hair loss.

Once the cause of hair loss is determined, the dermatologist can create a personalised treatment plan specifically designed to address the patient’s unique needs. This hair loss treatment may incorporate various strategies to not only prevent further hair loss but also encourage healthy hair regrowth.

Can Hair Loss Be Prevented?

Here are some strategies to help you maintain healthy hair:

• Eat a Balanced Diet: A diet rich in vitamins, minerals, and proteins can help protect your hair. Include foods rich in omega-3 fatty acids, iron, biotin, and vitamin E.
• Avoid Tight Hairstyles: Hairstyles that exert tension on the hair, such as ponytails or braids, can strain your hair follicles, potentially resulting in traction alopecia.
• Quit Smoking: Smoking has been linked to baldness in men. Smoking cessation may reduce your risk.
• Limit Heat and Chemical Styling: Excessive use of heat-styling tools, chemical treatments, and dyes can damage hair, making it brittle and prone to breakage.
• Protect Your Hair From UV Rays: Wear a hat or scarf during prolonged sun exposure and use a hair product with sun protection.
• Do Not Brush Wet Hair: Wet hair is more prone to breaking. Use a wide-toothed comb instead of a brush to detangle your hair once it is dry.
• Manage Your Stress: Manage stress-induced hair loss by incorporating techniques like meditation, yoga, or other stress management methods into your routine.
• Exercise Regularly: Regular exercise increases overall health, which can help promote healthier hair growth.
