What You'll Learn
Menopause causes dehydration, leaving nails brittle and weak
Menopause is associated with a decrease in hormone levels, specifically oestrogen and progesterone. This hormonal change can lead to a range of symptoms, including dehydration, which in turn can cause nails to become brittle and weak.
Oestrogen plays a crucial role in maintaining hydration by helping the body retain water. It does this by maintaining the permeability of cells, controlling how much water enters or leaves them. When oestrogen levels drop during menopause, this permeability decreases, leading to a build-up of fluids outside the cells, resulting in swelling or oedema. Additionally, oestrogen's role in regulating fluid and electrolyte balance is impaired, causing an increased loss of sodium through urination and reduced absorption of electrolytes from the gut. This fluid and electrolyte imbalance further contributes to dehydration.
Progesterone, another key hormone involved in menopause, acts as a diuretic, increasing urination and causing the loss of essential electrolytes such as sodium, potassium, chloride, and magnesium. This depletion of electrolytes exacerbates dehydration and can have adverse effects on overall health.
The dehydration caused by these hormonal changes can lead to brittle and weak nails. Nails, composed of the protein keratin, require moisture to stay healthy. When there is insufficient moisture, nails can become dry, brittle, and prone to splitting and cracking.
To counteract the dehydrating effects of menopause, it is crucial for women to focus on staying adequately hydrated. This can be achieved by increasing water intake, aiming for eight to eleven glasses of water daily, and consuming foods with high water content, such as fruits and vegetables. Staying hydrated can help mitigate the negative impacts of dehydration on nail health and overall well-being.
Additionally, there are specific measures that can be taken to support nail health during menopause. Moisturising regularly, especially after washing hands and before bed, can help combat dryness. Wearing gloves when doing household chores involving detergents and when going out in cold weather can also protect nails from further dehydration and environmental damage. Keeping nails short and filing them regularly can help prevent splitting. While nail hardeners can provide extra protection, they should be used sparingly as prolonged use can have the opposite effect, drying out nails further.

Nails are made of keratin, a protective protein
While there is limited information on how fast nails grow after menopause, it is known that lower oestrogen levels during menopause can lead to dehydration, causing nails to become brittle and weak. Nails are made of a tough protective protein called keratin, which also makes up your hair and skin. Keratin is a hardening protein that builds nails and makes them less prone to scratching or tearing than other types of cells in the body.
Keratin is composed of 54 kinds of proteins, with two main types: Type I and Type II. Type I consists of 28 keratins, 17 of which are skin cell (epithelial) keratins, and 11 are hair keratins. Most Type I keratins consist of acidic, low-weight proteins. They help protect cells from internal forces in the body, such as mechanical stress. Type II keratins consist of 26 kinds of keratins, 20 of which are skin cell keratins, and six are hair keratins.
Keratin is a naturally occurring protein in the body, and it helps to keep hair, skin, and nails healthy and strong. Keratin treatments, such as shampoos and conditioners, can also improve the appearance and strength of hair. Similarly, there are nail treatments containing keratin that can strengthen and protect nails, making them less prone to breakage and other damage.
The speed of nail growth is influenced by various factors, including genetics, overall health, age, nutrition, blood circulation, hormones, exposure to injury or trauma, and the environment. Good nail hygiene practices and a balanced diet rich in essential nutrients like biotin, protein, and vitamins can promote stronger and faster nail growth.

Nail growth is influenced by genetics, health, and age
Fingernails grow at an average rate of about a tenth of a millimeter per day, or 3.47 millimeters per month. However, this rate can vary depending on several factors, including genetics, health, and age.
Genetics play a role in nail growth, as individuals with certain genetic predispositions may experience faster or slower nail growth rates. For example, the nails on the dominant hand tend to grow faster, and the nails on longer fingers may also grow more rapidly. Additionally, the little finger's nail typically grows slower than the others.
Health is another critical factor influencing nail growth. Nutritional deficiencies, such as a lack of iron or vitamins, can lead to brittle, weak, and peeling nails. Chronic conditions, hormone imbalances, and circulation issues may also impact nail growth. For instance, lower oestrogen levels during menopause can cause dehydration, resulting in brittle and weak nails.
Age is a significant determinant of nail growth, with nail growth rates typically peaking during puberty and then declining as hormone levels stabilize with age. As individuals get older, they may observe changes in their nails' appearance, texture, thickness, colour, and shape. These changes can be a natural part of ageing or indicate underlying health conditions. For example, longitudinal melanonychia commonly develops in darker-skinned individuals as they age, and dramatic shape changes, such as clubbing, can indicate long-term oxygen deprivation.

Nutritional deficiencies can cause slow nail growth
While menopause does not directly cause slow nail growth, it can lead to dehydration, leaving nails brittle and weak. This is due to lower oestrogen levels, which can also cause dry skin.
Nail growth is influenced by various factors, including genetics, overall health, age, nutrition, blood circulation, hormones, trauma, and the environment. Nutritional deficiencies can cause slow nail growth, and even ridges in your nails, which may run vertically or horizontally. Essential nutrients such as protein, biotin, vitamins A and D, zinc, and iron promote nail growth.
Protein deficiency can lead to soft, thin nails, while a prolonged state of starvation can cause a 40-50% reduction in body weight and fissured nails. A nutritional syndrome called Kwashiorkor, caused by severe protein malnutrition, results in nail changes such as increased sodium and calcium concentrations and decreased magnesium concentrations.
Zinc deficiency can cause Beau's lines (transverse linear depressions) and white spots on your nails. Iron deficiency can lead to vertical nail ridges and koilonychia (spoon nails), which have a scooped-out depression in the middle.
To promote nail growth and overall nail health, ensure you consume a balanced diet rich in essential nutrients. Include nutrient-dense foods such as eggs, nuts, seeds, legumes, dark-green leafy vegetables, cereals, and meat in your diet.

Nail hardeners can strengthen nails but may cause brittleness
While menopause does not directly impact nail growth, hormonal changes during menopause can cause nails to become brittle and weak. This is due to lower oestrogen levels leading to dehydration, which can affect the health of your nails. Nails become more brittle and prone to breakage as we age, and menopause can exacerbate this.
Nail hardeners are a type of nail treatment that can help strengthen nails and reduce breakage. These products create a protective coating on the surface of the nail, providing a barrier against physical injuries and improving nail structure. However, it is important to use nail hardeners sparingly as prolonged use can break down the nail over time. Formaldehyde, a common ingredient in nail hardeners, can cause brittleness, so it is recommended to limit or avoid its use. Instead, look for hydrating and nourishing ingredients, such as cuticle oils and natural oils like olive and coconut oil, to keep your nails moisturized and prevent breakage.
Nail strengtheners, on the other hand, work to improve the nail from within. These products, such as serums and oils, help restore moisture to the nails and address dryness and brittleness. Protective products, like base coats, act as a layer of armour, sealing the nail to prevent breakage and damage. It is important to note that nutrition, hydration, proper care, and minimizing damage are key factors in promoting nail health and growth.
Additionally, certain vitamins and supplements can help improve nail health and reduce breakage. Biotin, also known as vitamin B7, has been shown to reduce nail breakage and increase overall nail health. Calcium and peptides can also improve nail flexibility and reduce brittleness, while antioxidants like green tea extract and vitamin E can protect nails from environmental damage.
While nail hardeners can provide a quick solution to strengthen nails, it is important to be mindful of the potential for brittleness with prolonged use. Combining nail hardeners with nail strengtheners, proper hydration, and a balanced diet can help promote overall nail health and reduce breakage.
