Hormone replacement therapy (HRT) is a treatment for symptoms of hormonal deficiency, such as menopause. HRT can affect nail texture and appearance, with some reporting faster nail growth and stronger nails, while others report the opposite. The relationship between HRT, nail growth, and texture is complex and depends on various factors, including the type of HRT, underlying health conditions, and individual differences. While HRT may influence nail growth and texture, it is not typically prescribed for nail-related issues alone due to the need to carefully weigh the risks and benefits of this treatment.
| Characteristics | Values |

What You'll Learn
Estrogen and testosterone impact nail growth and texture differently
Oestrogen plays a role in maintaining healthy nails. Research suggests that oestrogen encourages collagen production and boosts cholesterol content in the nail plate. After menopause, oestrogen levels drop, leading to a 25% decrease in collagen, which can contribute to brittle nails. This decrease in oestrogen also causes a decrease in keratin levels, which may make the fingernails weak and brittle.
Hormone replacement therapy (HRT) can help keep nails strong and prevent them from breaking easily. However, it is not typically prescribed for brittle nails alone, as the risks must be weighed against the benefits. HRT is not suitable for everyone.
Some sources suggest that HRT has been shown to affect nail texture and appearance. For example, one source noted that their nails grew more slowly when they were off oestrogen. Another source observed that their nails became thinner and more prone to chipping after starting oestrogen. Conversely, testosterone is believed to cause stronger, thicker nails.
Androgen replacement therapy (ART) has been shown to promote nail growth in patients with late-onset hypogonadism syndrome. This phenomenon is likely attributed to the androgen replacement therapy, as the spacing between the ridges widened in concordance with the strengthening of the therapy.

HRT is not typically prescribed for brittle nails alone
While HRT can improve nail health, it is not typically prescribed for brittle nails alone. This is because the risks of HRT are weighed against its benefits, and it is not suitable for everyone. Oestrogen plays a role in maintaining healthy nails, and research in this area is ongoing.
Oestrogen is thought to work by encouraging collagen production and boosting cholesterol content in the nail plate. After menopause, oestrogen levels drop, leading to a 25% decrease in collagen, which can contribute to brittle nails. However, other factors can also cause brittle nails, including fungal infections, psoriasis, thyroid problems, diabetes, and certain medications such as chemotherapy, retinoids, and antibiotics. Repeated exposure to water, mechanical microtraumas, and certain chemicals can also damage the nail plate and affect nail health.
Additionally, nutritional deficiencies, such as a lack of iron, biotin, vitamin B7, and vitamin B12, can weaken nails and make them more prone to brittleness. A healthy, balanced diet that includes fatty fish, fresh fruits, eggs, seafood, nuts, seeds, and leafy greens can promote nail health and prevent brittleness.
While HRT may not be prescribed solely for brittle nails, it can be considered as a treatment option for menopausal symptoms, which may include nail changes. It is important to consult a doctor to discuss the risks and benefits of HRT and determine the most suitable treatment plan.

Menopause causes changes in nails due to reduced oestrogen levels
The menopause transition can cause nails to become drier and more brittle. Nails are made from layers of a protective protein called keratin, which also makes up hair and skin. When there is too little moisture in the nails, they can become dry and brittle. This is why nail changes caused by menopause are likely to be linked to the natural drop in oestrogen and the dryness of the skin.
Other non-hormonal causes of brittle nails include trauma from cosmetics, such as gels and false nails, as well as the repeated washing and drying of nails. Certain chemicals are known to affect the nail plate and damage the lipids that support good nail health. This includes the preparation and removal of nail polish. Longer nails are associated with more rapid dehydration.
Hormone replacement therapy (HRT) can be used to treat brittle nails. However, it is not typically prescribed for brittle nails alone due to the potential risks involved. Transdermal estradiol is probably safer than oral oestrogens as coagulation factors are not induced in the liver, and HRT is safer if a minimal duration and dose of progestogen are used. HRT can also be used to treat other menopause symptoms, such as flushes, sweats, and vaginal dryness.
In addition to HRT, there are other ways to improve nail health during menopause. This includes maintaining a healthy and balanced diet, which may include fatty fish, fresh fruits, eggs, seafood, nuts, seeds, leafy greens, and water-rich foods. Certain supplements may also be beneficial, such as biotin (vitamin B7), collagen peptides, iron, biotin, vitamin B12, and keratin and silicon-based formulas. It is recommended to consult a doctor before considering supplements.

Certain chemicals and mechanical microtraumas damage nails
While HRT is not typically prescribed for brittle nails alone, oestrogen plays a role in maintaining healthy nails. Oestrogen encourages collagen production and boosts cholesterol content in the nail plate. After menopause, oestrogen levels drop, leading to a 25% decrease in collagen, which can contribute to brittle nails.
Certain chemicals are known to affect the nail plate and damage the lipids that support good nail health. These chemicals increase the chances of brittle nails. Nails can be damaged both by preparing the nails and removing nail polish. Longer nails are associated with more rapid dehydration.
Some of the chemicals found in nail salons include toluene (found in nail polish and fingernail glue), formaldehyde, and dibutyl phthalate, sometimes referred to as the "toxic trio". Toluene can cause dry or cracked skin, headaches, dizziness, and numbness, irritate the eyes, nose, throat, and lungs, and damage the liver and kidneys. Formaldehyde is a preservative that has been recognized by the National Cancer Institute as a potential cancer-causing substance. It is also among the most common substances that cause allergic contact dermatitis.
Repeated or frequent mild forces over a long period can cause microtrauma to the nails. This can occur when performing activities that alone may not cause pain but can result in inflammation when repeated. For example, a tendon being repeatedly compressed on movement, such as against the carpal bone complex when typing. So-called mechanical microtraumas – that is, repeated small bumps and knocks – can lead to nail fragility. This may be particularly relevant if you work in a manual job.

Nutritional deficiencies can weaken nails
While HRT can influence nail growth, it is not typically prescribed for brittle nails alone. This is because the risks of HRT must be weighed against its benefits. Oestrogen does play a role in maintaining healthy nails, and after menopause, oestrogen levels drop, leading to a 25% decrease in collagen, contributing to brittle nails. However, nutritional deficiencies can also be a significant cause of weak nails.
Nails are predominantly made up of keratin, a protein integral to the nail tissue's formation. A sufficient supply of essential nutrients is required to keep nails robust and resilient. Nutritional deficiencies can produce significant changes in the nail plate, and anomalies can also affect the nail bed. For example, a magnesium deficiency can result in weak, flaky nails prone to breakage. Iron deficiency anaemia can also lead to lower iron content in the nails.
Protein deficiency can cause Beau's lines, transverse linear depressions in the nail plate, and is one of the most common signs of nutritional deficiencies in nails. Malnutrition, in general, can lead to nail changes, with marasmus resulting in a 40-50% reduction in body weight and causing fissured nails and impaired nail growth. Kwashiorkor, a nutritional syndrome due to severe protein malnutrition, causes soft and thin nails.
Certain chemicals are known to affect the nail plate and damage the lipids that support good nail health. Having your hands in water repeatedly or for long periods can also damage the nail plate, causing more brittle nails. Mechanical microtraumas, such as repeated small bumps and knocks, can lead to nail fragility.
Supplements such as biotin (vitamin B7) and silicon have been shown to improve nail health in some cases, although the optimal duration of treatment has not been determined. A healthy and balanced diet is essential for good nail health, and adequate intake of vitamins and minerals facilitates nail health.
