Q: What types of supplements can I take (or foods should I eat) to promote strong, healthy hair?
— Meghan B., San Francisco

A: Thank you for your query, Meghan! I've asked David Kirsch, renowned celebrity fitness and diet expert, for his professional advice:

The right vitamins and minerals play a major role in keeping your hair healthy. It is important to include B-6, biotin, folic acid, and minerals such as magnesium, sulfur, silica and zinc in a supplement program to maintain healthy hair. A natural way to get some of these vitamins and minerals is through eating a diet that includes foods like turkey breast, wild salmon, beans and yogurt.

If you're always on the go, try a fast-absorbing nutritional supplement like David Kirsch Super Juice, which was created for clients as an alternative to taking a daily multivitamin pill, and is a powerful wellness booster and beauty enhancer.
