What is Hair Loss (Androgenetic Alopecia)?

Androgenetic alopecia is a hereditary condition in which hair follicles become sensitive to hormones called androgens, particularly dihydrotestosterone (DHT). Over time, affected follicles shrink and produce thinner, shorter hairs. In men, this often appears as a receding hairline and thinning at the crown. In women, it usually shows as diffuse thinning and a widening part while the frontal hairline is preserved. The condition is progressive, so starting treatment earlier tends to preserve more hair.

Who it's for

You may benefit from an evaluation if you notice:

• A receding hairline or thinning at the temples
• Thinning at the crown or a widening part
• Finer, shorter hairs than before
• More scalp showing under bright light or in photos
• Sudden, patchy or heavy shedding, which may point to a different cause and should be checked

How we treat it at Egg Clinic

Diagnosis comes first. A dermatologist reviews your history and examines the scalp, often with a magnified scalp scope, to assess hair density and follicle size. Blood tests may be recommended to check for contributing factors such as thyroid disease, iron deficiency or hormonal imbalance.

Treatment is tailored to you and may include topical minoxidil to prolong the hair growth phase, and oral medication such as DHT-blocking drugs for eligible patients, prescribed only after a physician's assessment. In-clinic options can include scalp injections of growth-supporting solutions and platelet-rich plasma (PRP) in suitable cases. Scalp care for dandruff or inflammation is also addressed, since a healthy scalp supports hair growth. Hair transplant referral can be discussed for advanced cases.

What to expect

Your first visit includes a scalp assessment and a discussion of options, side effects and expectations. Scalp injections take about 20 to 30 minutes, and you may feel brief stinging; mild redness or tenderness usually settles within a day. Some people notice temporary shedding in the first weeks of treatment, which is often a sign of new growth cycles. Visible improvement typically takes three to six months, and continued treatment is needed to maintain results. Medications can have side effects, which your physician will review. Results vary between individuals.

Aftercare

• Use prescribed medication consistently, as results depend on regular use
• Avoid washing hair for the rest of the day after scalp injections
• Skip saunas, alcohol and strenuous exercise on the day of injections
• Use a gentle shampoo and avoid harsh chemical treatments
• Eat a balanced diet and manage stress and sleep
• Attend follow-up visits so progress can be measured

Frequently asked questions

Is pattern hair loss reversible?

Treatment may help slow thinning and regrow some hair, especially when started early. Long-standing bald areas respond less, and results vary.

Can women use hair loss medication?

Some options are suitable for women and some are not, particularly during pregnancy. Your physician will recommend only what is appropriate for you.

What happens if I stop treatment?

Hair gained through treatment usually gradually thins again after stopping, because the underlying condition continues.
