Supplements like Nutrafol, RenewGlow, and Ouai can help with hair loss, nail-breakage, and even dry, dull skin.
Picture it: You’re getting ready for work in the morning, brushing the bed head from your hair, when you see it — a tangle of strands the size of a small animal stuck in the bristles. Ugh.
Whether it’s due to age, stress, or hormonal issues like the post-baby blues, hair-thinning isn’t something anyone celebrates. It’s also something loads of people overcome every year.
Don’t panic. None of these situations indicate a lifetime sentence of brittle hair and thin ponytails with annoying gaps. Hair vitamins can help reverse thinning, speed up growth, and improve the texture of your ‘do without a host of topical products or an hours-long hair-care routine.
The other awesome thing about hair vitamins is that they also help the body systems that regulate your nails and skin. So, with any hair vitamin, you’re also getting bonus nutrition to freshen up your look overall.
Beyond the Hairbrush - Other Cool Benefits of Hair Vitamins
Trying to quit those expensive nail extensions? Oftentimes, after months of abuse with glue and acrylic, nails can be soft, thin, and easily broken. Your nail tech might recommend biotin. Also known as vitamin B7, biotin is a primary ingredient in most hair vitamins. And that same vitamin helps your body convert nutrients from food into energy for your body to grow new hair, skin, and nail cells.
Ever wonder why hair stylists recommend people take prenatal vitamins to encourage thicker, stronger hair growth? Many prenatal vitamins have biotin, as well as other vitamins beneficial to hair — like vitamin C.
And speaking of vitamin C, did you know that it has the potential to be the most abundant antioxidant in your skin?! Humans can’t synthesize vitamin C on our own; we have to consume it through food and drink. But when we do, this powerhouse vitamin acts as a defender against cell damage from free radicals. That’s right: Vitamin C helps to prevent signs of premature aging.
It’s time you stopped suffering for beauty and started thriving for it instead with a hair vitamin that nourishes your body inside and out. So, which hair vitamin will give you the biggest bang for your buck? Here’s what our research showed…
