Hormones play a significant role in nail health and growth. While testosterone, the primary male sex hormone, contributes to the development of strong and healthy nails, oestrogen helps nails grow and stay hydrated. Hormonal imbalances can cause various nail problems, including brittle nails, slow growth, and changes in texture. Additionally, the thyroid, the hormone regulation centre, can affect nail health. Proper nail care, a balanced diet, and addressing hormonal imbalances are essential for maintaining healthy and strong nails.

Oestrogen helps nails grow strong and healthy by keeping them hydrated
Oestrogen, a beauty-promoting hormone, helps nails grow strong and healthy by keeping them hydrated. Oestrogen helps to maintain water in body tissues, and therefore, lower oestrogen levels can lead to dull, yellow nails that are more prone to breakage. This is why women going through menopause often experience dry and brittle nails.
Oestrogen is also responsible for promoting collagen production and skin hydration, thickness, elasticity, and improved barrier function. During pregnancy, oestrogen and progesterone levels are at their highest, which is why many women experience rapid nail growth during this time.
Hormones play a significant role in nail health, and changes in hormone levels can cause noticeable differences in the appearance and health of nails. For example, vertical lines on fingernails are indicative of a growth hormone deficiency. Additionally, the parathyroid glands, located near the thyroid gland in the neck, regulate calcium and vitamin D. A deficiency in parathyroid hormone can lead to brittle nails, which can be treated by supplementing calcium and vitamin D.
While hormonal changes can affect nail health, it is important to note that changes in nail health due to hormones occur gradually over time, typically over a period of four to six months. Dramatic changes in nail health are more likely to be caused by other factors, such as illness or thyroid problems, rather than hormones.
Furthermore, androgen replacement therapy has been shown to promote nail growth in patients with late-onset hypogonadism syndrome. In one case, a patient noticed a distinctive "washboard-like" pattern on his fingernails, which was attributed to the strengthening of his androgen replacement therapy.

Testosterone helps develop strong and healthy nails
While oestrogen is often regarded as the hormone responsible for strong and healthy nails, testosterone also plays a crucial role in nail health. Testosterone is a hormone that regulates development, physiology, reproduction, and behaviour. Age-related testosterone declines are common, and these decreases can be detected in men's fingernails.
Testosterone is necessary for protein synthesis, specifically keratin, which is a key component of nails. Dr. Jonathan Wright, a renowned expert in this field, highlights the importance of testosterone in nail health. He asserts that in addition to nutrient intake, the body's digestive health determines the absorption and utilisation of these nutrients for nail growth and maintenance.
Furthermore, testosterone influences nail health by interacting with other hormones. For example, testosterone metabolises into dihydrotestosterone (DHT), which can impact hair follicles and lead to hair loss. Additionally, testosterone imbalances can result in excess androgen hormones, causing unwanted body hair growth. Thus, maintaining balanced testosterone levels is crucial for nail health and overall well-being.
The health of an individual's nails can provide valuable insights into their overall health and hormone status. Nails act as a matrix, absorbing keratin and hormones from the blood. Changes in nail structure, such as lifting, separation, and adhesion issues, can indicate underlying hormonal imbalances. Therefore, nail technicians and healthcare practitioners should be aware of these signs and suggest appropriate care or medical attention when necessary.
In summary, testosterone is essential for strong and healthy nails. It contributes to protein synthesis and interacts with other hormones to regulate nail health. By understanding the role of testosterone, individuals can better manage their nail care and overall wellness.

Thyroid problems can cause changes to body hormones, affecting nails
The thyroid is a butterfly-shaped gland in the neck that produces hormones regulating various bodily functions, including nail growth, strength, and thickness. Therefore, thyroid problems can cause changes to body hormones, affecting nails.
Thyroid hormones play an important role in nail development by stimulating growth-promoting nail cells to differentiate into specialized structures. They also affect protein synthesis, inhibiting the body's ability to maintain healthy nails. Specifically, thyroid hormones stimulate the production of keratin, a protein used for healing wounds and making up the framework of nails. This results in stronger and thicker nails that are less prone to breakage.
An underactive thyroid, or hypothyroidism, can cause nails to become brittle and dry, breaking easily. It may also lead to slow nail growth and the development of ridges on nails. In contrast, an overactive thyroid, or hyperthyroidism, may result in thin and brittle nails, or "spoon-shaped" nails, also known as Plummer's nails or onycholysis.
Nail technicians can play a role in the early detection and diagnosis of thyroid disorders by noticing changes in their clients' nails. According to a 2022 study, those with a thyroid disorder frequently report nail brittleness. Additionally, those with autoimmune thyroid disorders, such as Hashimoto's disease, had a higher percentage of nail brittleness than those with non-autoimmune thyroid conditions.
It is important to note that while thyroid problems can affect nail health, other factors also influence nail strength and growth, including nutrient status, amino acid availability, and overall health.

Hormonal imbalances can cause brittle nails, slow growth and texture changes
Hormonal imbalances can have a significant impact on nail health, causing brittle nails, slow growth, and changes in texture. Estrogen, for example, helps maintain nail moisture and flexibility. Lower estrogen levels can lead to dry, brittle nails that are more prone to breakage. Similarly, during menopause, declining estrogen levels can result in increased nail brittleness and slower growth.
The thyroid hormone also plays a crucial role in nail health. Thyroid disorders, such as hypothyroidism and hyperthyroidism, can cause changes in nail growth and appearance. Hypothyroidism can lead to thick, dry, and brittle nails, while hyperthyroidism may result in soft, thin nails prone to splitting. Additionally, cortisol, known as the stress hormone, can impact nail health. Chronic stress and elevated cortisol levels can weaken the immune system, making nails susceptible to infections and fungal growth.
Hormonal changes during pregnancy can also affect nail health. The dramatic increase in estrogen and progesterone levels during pregnancy can lead to rapid nail growth and changes in texture. Furthermore, hormonal imbalances can disrupt the production of keratin, a protein essential for nail strength and growth, resulting in slow nail growth and weak nails.
While hormonal fluctuations during the menstrual cycle may not significantly impact nails, prolonged hormonal imbalances can cause noticeable changes. Managing stress, engaging in regular exercise, and getting adequate sleep can help maintain hormonal balance for healthy nails. In some cases, medical interventions such as hormone replacement therapy may be recommended to address hormonal imbalances affecting nail health.
It is important to note that nail health can also be influenced by nutrient status, amino acid availability, thyroid function, and overall lifestyle factors. Maintaining a healthy and balanced diet, staying hydrated, and incorporating nutrient-rich foods can promote nail strength and overall health.

Puberty and pregnancy can cause hormonal changes that affect nail growth
Puberty is usually the most tumultuous time for hormone levels, which can affect the rate of nail growth. Nail growth is said to peak during puberty and decline as hormone levels balance out with age. During puberty, the body experiences a surge in sex hormones, including oestrogen, which helps nails grow strong and healthy by retaining water in body tissues.
Hormones play an important role in the health of hair and nails. For example, androgen hormones such as testosterone and DHEA determine hair growth. An imbalance in testosterone metabolites can lead to hair loss and the growth of unwanted body hair. Similarly, low oestrogen levels can contribute to dull, yellowish fingernails.
Pregnancy is another period of significant hormonal changes, with oestrogen and progesterone levels climbing to the highest levels in a woman's lifetime. These hormonal shifts during pregnancy can result in rapid nail growth. However, it is important to note that the effects of hormones on nails may be more gradual, typically taking four to six months for noticeable changes to occur.
The thyroid gland, often referred to as the "hormone regulation centre," also plays a crucial role in maintaining healthy nails. Problems with the thyroid can impact hormone levels, which may eventually show up as changes in the nails, such as onycholysis (loosening and softening of the nails).
While hormonal fluctuations can influence nail growth and health, other factors are also at play. Nutrient status, amino acid availability, thyroid function, and overall health contribute to the growth and strength of nails. Maintaining a balanced approach to hormone and overall health is key to promoting healthy nails.
