Which Hormones Affect Hair Growth?

1. Androgens (Testosterone and DHT)

Dihydrotestosterone (DHT) is one of the primary hormones associated with hair thinning.

High DHT levels can:

• Shrink hair follicles

• Reduce hair thickness

• Cause male and female pattern hair loss

• Slow new hair growth

Women with PCOS often experience elevated androgen levels, which can trigger hair thinning.

2. Estrogen

Estrogen helps keep hair in the growth phase for longer periods.

Healthy estrogen levels:

• Promote thicker hair

• Reduce shedding

• Support scalp health

A decline in estrogen during menopause or after childbirth may cause significant hair loss.

3. Progesterone

Progesterone helps balance androgen activity in women.

Low progesterone may:

• Increase DHT production

• Cause hair thinning

• Trigger excessive shedding

4. Thyroid Hormones

The thyroid gland regulates metabolism and influences hair follicle function.

Both hypothyroidism and hyperthyroidism can cause:

• Dry hair

• Brittle hair

• Hair thinning

• Excessive hair fall

Thyroid disorders are among the most common endocrine causes of hair loss.

5. Insulin

Insulin resistance may contribute to hormonal imbalance.

High insulin levels can:

• Increase androgen production

• Worsen PCOS symptoms

• Promote hair thinning

6. Cortisol (Stress Hormone)

Chronic stress increases cortisol levels.

High cortisol can:

• Interrupt the hair growth cycle

• Push follicles into the shedding phase

• Cause diffuse hair loss known as Telogen Effluvium

Endocrine Disorders That Cause Hair Loss

Polycystic Ovary Syndrome (PCOS)

PCOS is one of the leading causes of hormonal hair loss in women.

Symptoms include:

• Irregular periods

• Acne

• Weight gain

Pregnancy and Postpartum Hormonal Changes

Many women experience thicker hair during pregnancy due to elevated estrogen levels. However, postpartum hormone fluctuations often result in temporary hair loss.

Diabetes and Insulin Resistance

Poor blood sugar control can affect blood circulation to hair follicles and contribute to hormonal hair loss.

• Increased hair shedding
