The colour of your fingernails can indicate a lot about your health. Typically, healthy fingernails have a pinkish hue with white tips. Any significant deviation from this colour can indicate an underlying health issue. For example, yellow nails can indicate a fungal infection or psoriasis, while bluish nails can be a sign of poor circulation or respiratory issues. In some cases, nail discolouration can be a result of certain medications or medical treatments. While nail colour changes are rarely the first sign of illness, it is important to monitor any changes in your nails and consult a doctor if you have any concerns.

What You'll Learn
Fingernail colour and health
The colour of your fingernails can indicate the overall health of your body. Nails are made of a protein called keratin, and healthy fingernails are typically smooth, with no spots or discolouration, and have a gentle curve that is consistent throughout the nail. They can vary in colour from light mauve or purple in darker skin tones to a pale or light pink in lighter skin tones.
However, any significant deviation from this typical pinkish hue can indicate an underlying health issue. For example, very pale nails may indicate illnesses such as anaemia, congestive heart failure, liver disease, or poor nutrition. White nails, also known as leukonychia, can be the result of trauma, anemia, dietary deficiencies, heart or kidney disease, poisoning, or liver problems such as hepatitis. Nails with a bluish tinge may indicate a lack of oxygen in the body, while green, blue, or black nails can be signs of bacterial infection, poor circulation, or other health problems. Yellow nails are often a sign of a fungal infection, and as the infection worsens, the nail may thicken and crumble.
Other changes in the shape and texture of your nails can also indicate health issues. For instance, vertical ridges in your nails are usually harmless and may be age-related, whereas horizontal ridges, called Beau's lines, indicate a pause in nail growth that could be related to a health issue such as high fever, vitamin deficiency, injury, diabetes, or peripheral vascular disease. Curved or "clubbed" nails may be inherited or associated with lung disease, inflammatory bowel disease, cardiovascular disease, or liver disease. Thick, overgrown nails may be hereditary or caused by conditions like psoriasis or poor circulation.
While nail changes can indicate underlying health issues, they are rarely the first sign of illness. Other symptoms usually appear first, and many nail abnormalities are harmless. If you are concerned about the appearance of your nails, it is recommended to consult a doctor or dermatologist.

Non-pink nails
While healthy fingernails are typically described as having a pinkish hue with white tips, it is not uncommon to observe deviations from this standard colour. Non-pink nails can manifest in various colours, including yellow, green, blue, black, or even white. These unusual colours are often indicative of underlying health issues. For instance, yellow nails can suggest a fungal infection or psoriasis, while bluish nails can be a sign of poor circulation or respiratory issues. Greenish-black discolouration is particularly concerning, as it may indicate a bacterial infection. In some cases, non-pink nails may exhibit as pale or white, which can be a symptom of anaemia or liver disease.
It is worth noting that nail discolouration is not always a cause for concern. Certain medications, such as tetracycline and naproxen, can cause photosensitivity, leading to discolouration. Additionally, conditions like psoriasis or thyroid disease may affect all nails, resulting in a uniform loss of the typical pink colour.
Beyond colour changes, other nail abnormalities can include pitting, ridges, brittleness, thickening, or a spoon-shaped appearance. These changes in texture and shape, along with discolouration, can be indicative of nutritional deficiencies, infections, or systemic diseases. Therefore, while non-pink nails may sometimes be harmless, it is important to monitor any persistent or concerning changes and consult a doctor if necessary.
While nail colour can provide insights into overall health, it is important to remember that it is just one piece of the puzzle. Other symptoms usually accompany nail changes as indicators of underlying health issues. For example, emphysema typically causes breathing problems long before the development of clubbed nails. Similarly, liver disease does not always result in white nails, and not everyone with white nails has liver disease. Therefore, while non-pink nails can be a warning sign, a comprehensive assessment of other symptoms is necessary for an accurate diagnosis.

Pink nails with darker tips
While nails are typically a pinkish hue with white tips, there are many reasons why the tips of your nails could be a darker shade of pink. This could be a normal variation of nail colouring, as the attachment of the nail to the nail bed can sometimes appear darker near the tips. This can be more pronounced if the rest of the nail bed is a lighter colour, which can happen due to poor circulation to the hands, cold hands, or other disease processes such as anaemia, hypothyroidism, or poor digestion.
If you are concerned about the appearance of your nails, it is important to consult a doctor, as changes in nail colour or texture can indicate underlying health issues. For instance, yellow nails can indicate a fungal infection or psoriasis, while bluish nails can be a sign of poor circulation or respiratory issues. Greenish-black discolouration can indicate a bacterial infection. However, it is important to note that nail changes are rarely the first sign of illness, and other symptoms usually appear first.
If you are looking to achieve pink nails with darker tips for aesthetic purposes, there are many creative options to explore. You can try a classic French tip manicure with a pink base, or alternate between solid pink, pink chrome, and white French tips for a playful yet formal look. For a bold statement, try magenta pink nails with solid colours and French tips. If you want something extra, add gold chrome drip tips, pink aura effects, and extra sparkles for a full goddess glam look.
For a soft and subtle look, opt for a milky pink base with abstract neon pink swirls or neon pink tips. You can also mix light and dark pink French tips and add gold chrome stars and rhinestones for a celestial vibe. If you're feeling adventurous, try a semi-sheer base with tiny red hearts on each nail for an adorable manicure.

Terry's nails
While Terry's nails are not harmful in themselves, they should be evaluated by a doctor as they can indicate a more serious issue. Treatment for Terry's nails focuses on addressing the underlying cause. To improve overall nail health, individuals can avoid biting their nails, clean them regularly, moisturise their nails and cuticles, protect their nails when using chemical products, and trim their toenails straight across.
If you notice any nail abnormalities, it is important to consult a doctor as nail changes can be a sign of certain health issues. For example, ridges or pits in the nails can be caused by underlying medical conditions. While nail changes are rarely the first sign of illness, they can provide valuable information about a person's health.

Fingernail growth
Fingernails are made of a protein called keratin, and they grow at an average rate of around 3.47mm per month or 0.1mm per day. The exact rate of growth depends on several factors, including age, sex, and the time of year. Typically, nails grow faster in young people, males, and during the summer months.
The growth rate of fingernails is about three times faster for a bitten nail compared to a healthy nail. This is because biting causes trauma to the nail, stimulating circulation in the nail bed. The little finger's nail grows slower than other fingernails, and it takes about three to six months for fingernails to regrow completely.
Good nail grooming practices can promote nail growth. Snagging, breaking, and biting can impact nail growth, while gentle massage can improve circulation to the nails. Cuticles, which are thin pieces of skin that protect the nail matrix, should be regularly moisturized and not cut too short, as this may expose the nail matrix or nail bed and lead to damage and infection.
While there is no proven way to make nails grow faster, various remedies can strengthen nails and prevent breakage, promoting overall nail health. Maintaining healthy nails is important not only for cosmetic reasons but also for the functional benefits they provide, such as protecting the fingers, improving grip, and providing a convenient way to scratch itches. Additionally, changes in nail colour, such as deviations from the normal pinkish hue, can indicate underlying health issues, so it's important to pay attention to the appearance of your nails.

Terry's nails are characterised by mostly white fingernails or toenails, resembling frosted glass, with a thin brown or pink strip at the tip. They usually affect all fingernails but can also be present on just one nail. While they can be a part of the typical aging process, they may also indicate underlying health issues such as liver scarring (cirrhosis) or congestive heart failure.
While changes in fingernail colour or texture can be indicative of certain health conditions, it is important to remember that nail appearance alone may not provide a definitive diagnosis. Other symptoms usually accompany nail changes as indicators of illness. Additionally, not everyone with a specific health condition will exhibit the same nail characteristics. Consulting a doctor is essential to receiving an accurate diagnosis and appropriate treatment.
