Why does hair fall out and how can it be linked to hormones?

Hair loss (alopecia) is often a signal of a hormonal problem.

Hormonal causes:

• Hypothyroidism - the most common cause
• Androgenic alopecia - Effects of the DHT hormone
• Postnatal period - fall in oestrogen levels
• Menopause
• Vitamin D deficiency
• Iron deficiency - often accompanied by thyroid problems

Dr Caunes' diagnostics:

1. TSH, T4, T3 - thyroid
2. Androgens (DHEA-S, testosterone, DHT) - androgenetic alopecia
3. Vitamin D, iron, ferritin

With treatment of the underlying condition, hair growth is restored within 3-6 months.
