Hair loss in women can be distressing, affecting confidence and overall well-being. While various factors contribute to female hair thinning, hormonal imbalances are a leading cause. Understanding which hormones influence hair loss can help in selecting effective treatments.

The Key Hormone Behind Hair Loss: Dihydrotestosterone (DHT)

One of the main culprits behind women's hair loss is DHT (dihydrotestosterone), a derivative of testosterone. While testosterone is often associated with male traits, women also produce small amounts, which can convert into DHT.

Excessive DHT levels cause hair follicles to shrink, a process known as miniaturisation. Over time, this leads to thinning hair, weaker strands, and eventual follicle dormancy. This condition, known as female pattern baldness (androgenetic alopecia), is one of the most common forms of hair thinning in women.

Other Hormones That Influence Hair Loss

While DHT plays a major role, other hormonal changes can also lead to hair thinning in women:

• Oestrogen: This hormone supports healthy hair growth. A decline in oestrogen levels, such as during menopause, can trigger excessive hair shedding.
• Progesterone: Progesterone helps balance testosterone levels. When progesterone decreases, testosterone converts more readily into DHT, contributing to women's hair loss.
• Cortisol (Stress Hormone): High cortisol levels due to chronic stress disrupt hair growth cycles, leading to increased hair thinning.
• Thyroid Hormones: Imbalances in thyroid function—whether hypothyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid)—can significantly affect hair density.

Treating Hormonal Hair Loss in Women

Managing hair loss caused by hormones often requires a combination of treatments:

• Minoxidil: A clinically proven topical solution that stimulates hair regrowth.
• Antiandrogen Medications: Drugs like spironolactone and finasteride help block DHT and reduce female pattern hair thinning.
• Hormone Replacement Therapy (HRT): Can support oestrogen and progesterone levels in postmenopausal women experiencing hair loss.
• Nutritional & Lifestyle Adjustments: A diet rich in hair growth nutrients, reducing stress, and addressing hormonal imbalances naturally can improve hair health.

Final Thoughts

Hormonal hair loss in women is often driven by DHT, but oestrogen, progesterone, cortisol, and thyroid hormones also play a role. By recognising how hormones affect hair thinning, women can explore effective solutions for regrowing thicker, healthier hair.
