Understanding Hormonal Hair Loss: A Practical Guide

Hormonal hair loss is one of the most common concerns clients bring to trichologists and hair care professionals. Understanding the patterns, triggers, and appropriate responses can transform your consultations from uncertain to confident.

Recognizing the patterns

Hormonal hair loss typically presents with specific patterns that differ from other forms of hair loss. The most common presentation is diffuse thinning across the crown and top of the scalp, while the hairline often remains relatively intact.

• Gradual thinning over months or years rather than sudden shedding
• Increased hair fall during washing or brushing
• Visible scalp becoming more apparent, especially under bright light
• Changes in hair texture—often becoming finer or less dense

Common hormonal triggers

Several hormonal transitions can trigger hair loss. Understanding these helps you ask the right questions during consultations:

Post-pregnancy changes

Postpartum hair shedding typically occurs 3-6 months after giving birth. While distressing, this is temporary and usually resolves within 6-12 months.

Perimenopause and menopause

As estrogen levels decline, the ratio of androgens increases, which can trigger hair thinning. This typically begins in the 40s but varies widely.

Thyroid imbalances

Both hypothyroidism and hyperthyroidism can cause diffuse hair loss. Always ask about energy levels, weight changes, and temperature sensitivity.

Having supportive conversations

• Acknowledge their concern without minimizing it
• Ask about recent life changes
• Explain that you can support scalp health while they explore hormonal factors
• Recommend they speak with their GP about hormone testing if appropriate
