8 Best Hair Growth Tips, According To 9 Experts

1. Nutrition and supplements

Nutrition plays a huge role in your hair health. “While investing in the right hair care products will make a huge difference to your hair’s health, you can also naturally boost your hair growth and thickness by eating the right foods,” says Eva Proudman, trichologist at Absolute Collagen. “Make sure your nutrition is genuinely adequate, particularly protein, iron, zinc and vitamin D, and get deficiencies checked with blood tests rather than guessing,” recommends Dr Adel.

In some cases, vitamins and supplements can deliver the levels you need. “Vitamin hair supplements shouldn’t be a substitute for a varied diet,” says Clarke. “But if you’re still struggling to get all the nutrients you need, supplements can help those with an unbalanced regime,” he says.

Look for protein, iron, zinc, vitamin B12, vitamin D, Omega 3 and the best biotin supplements. “B12 is especially important for vegans, as B12 is only found naturally in animal products,” says Kingsley. But it’s best to consult with a doctor and take a blood test before taking any supplements.
