There are various factors that can cause brittle nails, including aging, nutritional deficiencies, use of certain medications, exposure to drying chemicals, and frequent hand washing. In addition, certain medical conditions such as psoriasis, iron deficiency anemia, and thyroid gland disorders can also trigger brittle nails. Here is a complete overview of the factors causing brittle nails, as well as tips for improving and preventing them, cited from health.com on (25/4).

Here are some other reasons why nails are easily cracked: Nutritional deficiency: Biotin (vitamin B7), zinc, and iron are essential nutrients for nail strength. Lack of any of these nutrients can make nails brittle. Specifically, iron deficiency is related to nail brittleness. Medication influence: Certain types of medications such as retinoids, antiretrovirals, and chemotherapy can make nails prone to breakage. Trauma: Injuries or repeated microtrauma to the nails, such as biting or pulling nails, can weaken nails over time.

Influence of the environment: Cold and dry weather or exposure to harsh chemicals can reduce nail moisture and make them brittle. Medical conditions: Various medical conditions such as thyroid disorders, anemia, psoriasis, eczema, Raynaud's disease, osteoporosis, diabetes, and fungal infections can make nails easily breakable. Excessive hand washing: Frequent washing and drying of hands can reduce nail moisture and make them brittle. Nail care: The use of nail polish, nail extensions, and acetone-based nail polish removers can weaken nails and make them brittle.

If brittle nails are caused by aging or other environmental factors, a dermatologist or specialist in skin, nails, and hair may recommend the following approach to improve the situation. Maintaining moisture in the hands and nails can be done by using creams or lotions that contain lanolin or AHA. Consuming biotin supplements every day can also provide benefits. Applying a thin layer of nail strengthener that contains nylon fibers can also help.

The following are some steps to prevent easily brittle nails at home: Make sure the nails are always well-maintained and trimmed with a rounded shape using a nail file. Use gloves when doing household chores that involve the use of cleaning materials or if the hands are frequently exposed to water. Reduce the use of nail polish, fake nails, or nail polish removers that contain acetone.
