Understanding How Your Body and Hormones Affect Your Hair

Your hair tells a story of constant change. It is deeply influenced by the complex interplay of hormones in your body. From subtle shifts in texture to noticeable changes in thickness, understanding these changes helps you better care for your hair through every stage of life.

The science behind hormonal hair changes 

The relationship between hormone levels and your hair is intricate and dynamic. Each strand goes through a precise hair growth cycle, influenced by various hormonal changes that affect everything from growth rate to texture.

As noted in this article:

One of the main culprits behind hormonal hair issues is none other than estrogen. This hormone, often associated with femininity, is responsible for promoting hair growth and keeping our locks luscious and full. Unfortunately, as we age, our estrogen levels can decline, leading to thinner and more brittle hair.

 

But estrogen isn't the only hormone that can have an impact. Testosterone, the hormone typically associated with men, also plays a role in hair health. When testosterone is converted into dihydrotestosterone (DHT), it can shrink hair follicles, leading to hair loss and thinning.

Key hormones and their effects on hair

Thyroid hormones play a vital role in hair health, given they:

• Regulate the speed of hair growth

• Impact the hair shaft strength

• Control sebum production

• Influence hair texture changes

Estrogen levels affect:

• Overall hair thickness

• Hair volume

• Follicle strength

• Growth patterns

The impact of stress and hormones

The stress hormone cortisol can trigger significant changes:

Life stages and their impact on hair

Each life stage involves different hormones or associated levels and hormone changes, meaning your hair has an impact.

Puberty and adolescence

During puberty, hormonal fluctuations can cause:

• Changes in hair type

• Shift from straight hair to curly hair

• Alterations in hair's texture

• Modified curl pattern

Pregnancy and postpartum changes

Pregnant women experience unique hormonal shifts that affect their hair:

• Increased thickness during pregnancy

• Postpartum hair loss

• Changes in hair texture

• Alterations in growth patterns

Postmenopausal women often notice:

• Thinning at the crown

Common hormone-related hair concerns

Understanding androgenetic alopecia

This condition, linked to male hormones, can affect both men and women:

• Progressive thinning

• Changes in hair follicles

• Reduced growth phases

• Conversion of terminal hairs to vellus hair

The role of thyroid disease

The British Thyroid Foundation notes:

Severe and prolonged hypothyroidism and hyperthyroidism can cause loss of hair. The loss is diffuse and involves the entire scalp rather than discrete areas. The hair appears uniformly sparse. Regrowth is usual with successful treatment of the thyroid disorder, though it will take several months and may be incomplete. It is unusual for mild (e.g., subclinical) hypothyroidism or hyperthyroidism, or short-lived thyroid problems to cause hair loss.

Frequently asked questions

Can hormonal changes change hair?

Hormonal changes can significantly alter your hair's texture, thickness, and growth patterns. These changes can affect the shape of your hair follicles, leading to shifts in texture and density. Each stage of life brings different hormonal influences that can modify your hair's characteristics.

How do you fix hormonal imbalances in hair?

Addressing hormonal imbalances that affect hair requires a multifaceted approach. Start with a balanced diet, ensure adequate nutrition, and consider appropriate hormone replacement therapy if recommended by your doctor. Some people benefit from specific supplements, while others may need medical intervention, depending on their specific needs.

What does low estrogen hair loss look like?

Low estrogen levels typically cause overall thinning, particularly noticeable at the crown and hairline. This hair loss often presents as reduced hair volume and increased shedding. The remaining hair may become finer and show changes in texture.

Is female hormonal hair loss reversible?

Many female hormone-related hair loss cases can be improved or reversed with proper treatment. Success depends on factors like genetic predisposition, timing of intervention, and the underlying cause. Early treatment typically yields better results, and various treatment options are available depending on hair loss's specific cause and severity.
