What “It Could Mean”:
Melanonychia: “Dark vertical stripes can be caused by increased melanin production, which is sometimes benign but should always be evaluated.” Melanin is the pigment that gives color to our skin and hair, and it can also appear in nails.
Nail Melanoma: It’s rare, but “In rare cases, dark stripes may indicate skin cancer under the nail.” Early detection is key with any potential cancer.
What to Do:
“See a dermatologist or doctor immediately to rule out serious conditions.” Do not delay this step.
“Monitor for changes in stripe width, color, or texture” as this information will be helpful for your doctor.
5. Brittle or Grooved Nails with Stripes: Possible Thyroid or Hormonal Issues
When striped nails are also brittle or have deep grooves, it could point to hormonal imbalances.
What “It Could Mean”:
Hypothyroidism: “Underactive thyroid can cause brittle nails with ridges.” The thyroid gland plays a significant role in regulating metabolism and overall body functions, including nail health.
Hormonal Changes: “Pregnancy, menopause, or hormonal imbalances may affect nail health.” Fluctuations in hormones can impact nail growth and strength.
