3. Loose Nails
Traumas make nails weak. If the damage is severe, then you may see that your nails fall off. Loose nails occur without traumas also, but that’s a different story. Nails detach due to nail infection. They can fall off if your hormones are imbalanced. If you suffer from hyperthyroidism, then your nails may be loose and very weak. The same issue can happen to your toenails. The condition is scientifically called onychomycosis. This disease affects toenails in several ways, most of which lead to loose nails.

4. Thick Nails
Discoloration and thickness of nails can be a symptom of aging. Sometimes you need to look after yourself and take better care of hygiene. However, poor grooming is not always the main reason why nails become thick or discolored. For instance, this might be a sign of psoriasis. This condition affects the nails and the skin – they become thicker, rougher and tend to grow faster than usual. Another reason why you might have thick toenails and fingernails is a severe fungal infection. Talk to the doctor and ask what kind of treatment is needed to resolve the issue.
