The 28-year-old model has revealed the secret to her luscious locks is taking vitamins intended for pregnant women, while not having her hair dyed all the time amid the Covid-19 pandemic has also worked wonders on her stunning blonde tresses.
She said: "My hair is so much healthier as a result of the pandemic. It’s because I’ve left it to its own devices and not dyed it in almost a year – aside from touching up the front slightly – but I really don’t care for highlights anymore.
Even so, I swear by prenatal supplements. I’ve gone through a lot of trial and error with supplements for healthy hair, but prenatal vitamins have been the most helpful. I can’t take biotin – if I do, I get really painful, deep breakouts.
Most hair supplements marketed for growth don’t work for me, so I’ve been using prenatal vitamins for a while now as they give you essential nutrients, while keeping your skin and hair in great condition."
Hailey - who is married to pop star Justin Bieber - also revealed she is often seen with a "slicked back" hairstyle because she uses a bunch of hydrating oils and masks on her hair.
She added to SheerLuxe.com: "Day-to-day, slicked back hair is my go-to style. Most of the time it’s because I have about four different oils or masks in there and I like to let it sit.
“I’ll apply loads – castor oil, coconut oil and also Christophe Robin’s lovely nourishing formulas. I like to load my hair with hydrating products, put it up in a bun for two days and let everything absorb."
Meanwhile, Hailey recently revealed she tried following a plant-based diet in lockdown.
Alec Baldwin's niece decided quarantine would be a good time to make a change to her diet and whilst she gave the plant-based option a go for eight weeks, it wasn't for her.
She said: "I tried a plant-based diet for two months during quarantine. I felt great and I had a lot of energy, but it was not for me.
“I don't eat a strictly plant-based diet and I do still eat meat. I just don't eat a lot of it. I've picked up more fish, greens, and lentils."
