Take one look at the locks of Kim, Kourtney, Kendall, Kylie, Kris or Khloé Kardashian, and immediate envy ensues. It's no secret that as we age, our hair changes in color and texture (hello, frizzy grays!). But just how do the Kardashian women keep nourished hair through every color treatment and stage of life? Luckily for you, we found the all answers in a chat with their hair stylist and genius, Jen Atkin.

There's no better expert to chat hair with than Jen. Not only is she a Kardashian confidant and hair wiz, celebs like Chrissy Teigen, Jessica Alba, and Gigi and Bella Hadid have enlisted her as their prime hair consultant. Moreover, she has her own successful haircare range used by her clients called OUAI (pronounced way), sold through Sephora. That is, if you can get your hands on it; it sells out as soon as it's restocked. From tips for achieving youthful-looking hair to why your shampoo and conditioner shouldn't always match, read on as we pick the brain of the best hairstylist in the business.

How does our hair change as we age?

Your hair can lose elasticity so it breaks easier, which is caused by a dip in keratin levels. Hair can also start to grow in slower, the texture can change, and tresses can become drier as well. All are normal factors of aging, so I wouldn't get too worried since there's supplemental changes you can make to slow or prevent these things from happening.

How can we stop our hair from aging?

I really strongly believe that you will not see changes in your hair by just doing external remedies — you need to do internal as well. For years, I was sending clients to the health food store to get biotin and fish oil pills!

Our OUAI Thin Supplements formula includes ashwagandha extract, which is great for reducing stress levels (a major contributor to hair loss), and niacin, an ingredient that helps prevent blockage of cholesterol at the pores.

Can the way we wear our hair make us appear older than we really are?

Haircuts can make all the difference in your appearance. Make sure to consult with your stylist on what looks best on you given your lifestyle, age, etc. You want to wear something that complements you — and never want your hair wearing you.

What haircuts and styles will make us look more youthful?

I always say it all depends on you; every cut is different for everyone. I'm loving a short, chic bob or even a lob [long bob], which looks flattering on just about anyone, and is easy to manage.

What are the biggest mistakes women make when it comes to haircare and styling?

Most people buy their shampoo and conditioner from the same product line (volume, repair, clean, etc.) and don't realize that you usually need a different shampoo and conditioner variety for each. Fixing this common mistake can be the key to achieving your hair goals.

Aside from the right shampoo and conditioner, what three hair products should every woman own?

Use OUAI Treatment Masque ($46, Amazon) at least once a week for deep restoration. If you're crunched for time, apply to your strands pre-workout and braid in to let the nourishing ingredients absorb into the hair with the added heat from your exercise.

Christophe Robin Cleansing Purifying Scrub with Sea Salt ($52, Amazon) is a game changer. I love using this a couple times a week for a nice deep cleaning. It exfoliates the scalp and leaves you feeling refreshed.

The Dyson Supersonic Blowdryer ($399, Amazon) is super lightweight, quiet, and chic, with a powerful engine. This is the ultimate luxe blow-dryer. It's so small and easy to travel with, and dries the hair so much faster than the traditional blow-dryer.
