Finally, a few important things to know about hair supplements in Australia:
- Always consult your doctor before starting any new supplement, especially if you’re pregnant, breastfeeding, or have recently had surgery or been in an accident.
- Take your supplements as directed - exceeding the recommended dosage won't get you results faster, but it will cost you more money.
- If you're concerned about hair loss, chat to your health professional for personalised expert advice, because no two heads of hair are the same.
