In menopausal women, split toenails are often linked to hormonal fluctuations, particularly declining estrogen levels, which can cause dryness in the nail beds. Proper nail care can help manage this condition and may include the following:
Moisturizing the nails regularly
Avoiding prolonged exposure to hot water
Trimming toenails after soaking the feet in warm water
Using non-acetone nail polish removers
In some cases, addressing the underlying hormonal imbalance with HRT may also help improve nail health and reduce splitting.
