Can HRT Cause Hair Loss?

Hormone replacement therapy (HRT) is a type of treatment that restores hormones that decline gradually with age. Doctors often prescribe it for menopause symptoms such as, hot flashes, night sweats and vaginal dryness.

When it comes to hair health, the connection between HRT and hair loss is not straightforward, it varies from person to person. Some people might lose hair from HRT, however, others might find an improvement in their hair.

In this article, we share with you how HRT affects hair health, if it can cause hair loss, possible side effects, and advice for minimising the risk of hair loss.

What are HRT and Hair Loss?

HRT involves increasing hormones such as oestrogen and progesterone (or testosterone in some cases) to balance declining levels in the body. When menopause begins, the ovaries stop making hormones like oestrogen and progesterone, which can cause various symptoms. Hormone Replacement Therapy (HRT) provides these hormones to the body, which helps to reduce symptoms related to menopause.

While HRT can positively influence skin and hair health for many, it may also contribute to hair loss in some cases, depending on factors like the type of hormones used, dosage, and individual response.

Does HRT Cause Hair Loss?

HRT can sometimes lead to hair loss, and the effects depend on the type of therapy used. Here’s how different types of HRT might affect hair:

1. Oestrogen-based HRT: Oestrogen helps maintain a healthy hair growth cycle. When oestrogen levels drop, hair loss can occur. HRT with oestrogen may help slow this process.

2. Progesterone-based HRT: Progesterone can influence the hair growth cycle, and in some cases, it may cause hair shedding.

3. Synthetic HRT: Some individuals notice hair loss when using synthetic versions of hormone therapy.

4. Testosterone: While testosterone may promote hair growth for some, others experience hair thinning or loss, particularly on the scalp.

Hair loss related to HRT often begins gradually and typically shows as thinning around the crown or part line. This can be distressing, but not everyone on HRT experiences hair loss, and the extent can vary. It might take several months to observe how HRT impacts your hair.

Side Effects of Hormone Replacement Therapy (HRT)

The side effects of HRT vary depending on the type of medication and the hormones used. Some people experience no side effects, while others may notice mild to significant reactions. Here’s a breakdown of possible side effects:

1. Oestrogen-based HRT

Common side effects include:

• Breast tenderness or pain
• Nausea

• Itching
• Unexpected vaginal spotting or bleeding

2. Progesterone-based HRT

Side effects may include:

• Acne
• Headaches
• Breast tenderness or pain
• Nausea
• Diarrhoea
• Changes in menstrual cycles
• Dizziness
• Fatigue
• Mood swings
• Itching

3. Tibolone (Synthetic Hormone)

People using tibolone may experience:

• Pelvic or stomach pain
• Breast tenderness
• Vaginal bleeding or discharge
• Vaginal itching
• Thrush (yeast infections)

How Does Menopause Contribute to Hair Loss?

Menopause is a natural stage in a woman’s life that marks the end of her menstrual cycle. During this time, hormone levels, especially oestrogen, decrease, leading to several physical and emotional changes, including hair loss. The primary cause of hair loss during menopause is the reduction in oestrogen, which can result in thinning hair and, in some cases, bald patches. Menopause can also cause an increase in cortisol (the stress hormone), which can further affect hair growth.

Additionally, the hormonal shifts during menopause create an environment in the body that is less favourable for healthy hair growth. These changes often lead to thinning or even balding, particularly around the scalp. Women may also notice other hair-related changes, such as premature greying or the development of bald patches (alopecia).

1. Changes in Hair Pattern

As the hormonal changes progress, some women may notice a shift in their hair pattern. Hair might begin to grey earlier than expected, and some may experience bald patches or a condition known as alopecia. These changes are often noticeable compared to their previous hair growth patterns.

2. Thinning Hair

For many women, hair thinning during menopause can be distressing, affecting their confidence and emotional well-being. To help manage thinning hair, it’s recommended to use gentle hair care products that are specifically designed for thinning hair and to avoid harsh treatments like blow drying or chemical treatments.

3. Effects on Volume and Length

Menopause affects not only hair but also other parts of the body, such as a decrease in height (up to 1-2 inches), smaller breasts, and a reduction in fat around the pelvis. Additionally, skin changes may occur, including more wrinkles and age spots.

How to Manage Hair Loss on HRT?

Hair loss during HRT can be concerning, but there are various ways to manage it effectively. Below are practical tips to help reduce hair thinning and maintain healthy hair throughout HRT.

1. Avoiding Chemicals and Excessive Styling

Avoid using harsh chemicals like dyes and perms, as well as excessive heat styling, which can weaken and damage hair. Gentle styling and natural hair treatments can minimise hair breakage and thinning while on HRT.

2. Taking Multivitamins

Multivitamins with nutrients like biotin, iron, and Vitamin D support hair health by filling nutritional gaps that can cause thinning hair. Ensuring you have adequate nutrients can improve the strength and thickness of your hair.

3. Essential Oils

Essential oils like rosemary and peppermint can improve scalp circulation, promoting hair growth. Regular scalp massages with these oils can help stimulate hair follicles and improve overall scalp health.

4. Adjusting HRT Treatment

If hair loss persists, consider discussing your HRT treatment with a doctor. Adjusting the type or dosage of hormones can help mitigate hair thinning and optimise the benefits of HRT while minimising side effects like hair loss.

5. Lifestyle and Diet

A healthy diet rich in vitamins, minerals, and proteins is crucial for hair growth. Regular exercise, staying hydrated, and maintaining a balanced diet help improve blood flow and provide essential nutrients to your hair.

6. Stress Reduction

Stress can exacerbate hair loss by increasing cortisol levels. Practices like meditation, yoga, and sufficient sleep can help reduce stress, improving overall hair health during menopause and while on HRT.

7. Gentle Hair Care

Using sulphate-free shampoos and conditioners, along with avoiding tight hairstyles, can prevent additional damage to hair. Gently detangling with soft brushes will help minimise breakage, supporting healthy hair growth.

8. Medical Interventions

If lifestyle changes aren’t enough, medical treatments may help restore hair growth. These options stimulate hair follicles and promote thicker hair, particularly for more severe hair thinning.

Final Thoughts

Hormone replacement therapy (HRT) can lead to hair loss for some people, but it’s not a guarantee for everyone. The extent of hair shedding can differ greatly between individuals. Always consider taking HRT from a specialist HRT Clinic expert.

To help manage this, it’s important to eat a balanced diet rich in protein, keep the scalp clean, and use mild shampoos. Additionally, using hair products with specific vitamins and essential oils may help reduce hair loss and improve hair health.

Frequently Asked Questions

1. Does hair grow back after HRT?

Once hair follicles are permanently damaged or dead, no form of HRT will be able to restore hair growth in those areas. However, if the hair loss is due to hormonal changes and the follicles are still active, HRT may help stimulate hair growth over time.

2. Can too much oestrogen make your hair fall out?

When women approach menopause, progesterone levels drop, leading to an imbalance where oestrogen becomes dominant. This hormonal shift can trigger increased shedding and hair loss. Too much oestrogen in the body may contribute to this issue.

3. Does HRT make body hair thinner?

HRT can result in thinner body hair and may slow its growth, but it won’t entirely stop it. To fully remove unwanted body hair, treatments like laser hair removal or electrolysis would be needed.

4. Will my hair grow back if I start HRT?

If hair loss is due to hormonal changes, starting HRT may help encourage hair growth and reduce thinning. However, it’s important to work with a doctor to create a personalised treatment plan to address your specific needs.

5. Does lack of oestrogen cause hair loss?

Yes, low oestrogen levels can lead to hair thinning or loss. Oestrogen plays a key role in the hair growth cycle, and when levels drop, it can result in weaker, thinner hair.
