This blogger got into 'green' beauty for an extremely personal reason.

Liz Mimran was a teenager when she started losing her hair.

This is, obviously, not a common problem for someone so young to have.

"I tried every possible hair care line and supplement on the market [to stop the hair loss], but to no avail," writes Liz in an email. "Worse, some products only aggravated the problem and irritated my scalp."

Since this was before all-natural products had become a staple of the mainstream beauty market, Liz decided to research homeopathic and holistic remedies to see if they'd make a difference.

Liking what she read, she began to dip her toe into the world of "green" hair care. She started using products that contained less, if any, synthetics, as well as homemade concoctions.

And slowly but surely, her hair got healthier.

"A couple of months later, my hair loss diminished tremendously and my hair felt less greasy and fragile," Liz writes. "It did not happen overnight, but it worked."

That was it for Liz: She was now a green beauty product convert.

Two years later, she start blogging about her experiences to help others.

Her blog, Smells Like a Green Spirit, is a fun, down-to-earth guide for anyone interested in trying the sustainable beauty lifestyle.

"I try my best to help people navigate the world of organic and natural beauty and avoid some of the mistakes that I made when I first started my green journey," Liz says.

For example, just because a brand claims its product is "100% natural" or "organic" doesn't mean it is.

Sometimes brands greenwash, which means they claim to be eco-friendly through advertising and marketing but don't actually implement practices that minimize environmental impact.

Since Liz began exploring actual green, sustainable products when they weren't facets of cosmetic stores or beauty magazines, it was more of a challenge for her to find things that were the real deal.

Today, she gets notes from readers having the opposite problem — there are so many green products on the market that they simply don't know where to start.

So Liz gives the following advice: "Read the labels, take your time, and listen to your body. Certain ingredients are natural but that doesn't mean that your skin will react positively to it."

Liz is far from the only millennial to pledge herself to sustainable beauty. It's a movement that's become firmly embedded in the younger generations.

In fact, according to Fast Company,90% of millennials say they'll buy from a brand if they believe its social and environmental practices are legit.

And they have good reason to feel this way. According to the EPA, 30% of the trash in landfills is packaging. Beauty products are a $500 billion industry, so its packaging contributes significantly to that percentage. The more beauty brands commit to making their packaging more sustainable, the less they'll compromise our planet.

Due to climate change and a whole host of other environmental issues, millennials are living in an endangered world. As such, it's often appealing to them to purchase products that don't make things worse.

While Liz wholeheartedly believes investing in green beauty is about saving the planet, she also thinks it's important to focus on what we're are putting into and onto our bodies.

"I believe that the internet and access to [tons] of information has contributed to raising awareness of the significance of living in a more mindful way," Liz writes.

This attention toward personal well-being goes hand-in-hand with sustainability, which is why consumers like Liz look for products that highlight it when purchasing and recommending products.  

But it's not just about what they're made of — it's how they're packaged too.

Eco-friendly packaging is just as much a part of what makes a product sustainable as what's inside. Thankfully, Liz is noticing beauty brands making efforts there too.

"There's still a long way to go, but I have the impression that brands now understand that a product has to be eco-friendly from head to toe in order to 'earn' the sustainable/ethical label," Liz writes.

Since she's a known beauty blogger, she gets loads of products to review, so she's even more appreciative of repurposed or 100% recyclable packaging than the average buyer.  

Liz hopes her generation will continue to demand transparency from beauty brands as more and more go green — and not just for her skin's sake.

Holding companies to such high standards will not only keep us looking and feeling better, it'll help reinvigorate our planet. While they may be younger, millennials and generation Z understand that better than most because they're seeing firsthand the effects that decades of the alternative have made.

So, perhaps we shouldn't call green beauty a trend but rather a necessary shift.

After all, environmentalism as a whole isn't fashionable — it's the cornerstone of our future.
