Which doctor treats this
- Start with your primary care provider (family doctor or internist).
- They may send you to a dermatologist (skin doctor).
Back to school, work, or sports
- Most people keep up normal school and work. Rest when you need to.
Children, pregnancy, and older adults
- Black and Asian adults: Graying often starts a bit later on average.
Pregnancy and breastfeeding
- If you're pregnant or planning to be, tell your prenatal provider about this condition.
- Some skin medicines, like isotretinoin and retinoid creams, aren't safe in pregnancy.
- Don't start or stop any medicine on your own. Some are safe in pregnancy and some need to be changed.
- Ask before taking any pain reliever. The FDA advises avoiding ibuprofen and naproxen after 20 weeks unless your doctor says to.
- Breastfeeding: Most medicines are fine, but ask. The NIH LactMed database lists what's known about each one.

Graying is a normal part of life and isn't a sign of poor health.
