We know that acting schools gave her talent, but what about her beauty?
How does she get such shiny and glossy hair?
PerPopSugar, the answer is Olaplex Hair Perfector No.

3, a pre-strengthening shampoo that’ll protect your hair glands and spur hair growth.
And, Barrymore isn’t the only celeb who swears by this magic.
Kim Kardashian and Yara Shahidi have both used this product, according to PopSugar.

And if you’re doubtful about this celebrity praise, don’t be.
Olaplex doesn’t have any celebrity endorsements, so these reviews are 100% genuine!
Her hair is a very crucial aspect of her identity, perGlamour.
“Our hair really defines us,” she said to the outlet.
“People are their hair.
It’s such a powerful thing there are books written, there are industries, there are conventions!
Humans are hair-obsessed.”
“I have a full-blown addiction to the Sisley Nutritive Lip Balm,” she said.
“I also love Bioderma Micellar Water.
And my favorite hair mask is the Lazartigue Nourish Mask.
It doesn’t have protein, so you could really leave it in.”
While (sort of) expensive, her hair obsession has maintained her wonderful, luscious locks.
So, it can’t bethatbad to spend so much money on hair.
Plus, no one (not even us) can stop talking about her look.
