When we first interviewed then 15 year-old Ava Anderson on her new line of completely chemical-free beauty products, readers went wild over the natural bounty of goods.

Now the ever-enterprising teen is stepping into the hair care realm with the debut of a new shampoo and conditioner that meets the same non-toxic, vegan and organic levels as her other products.

The shampoo contains aloe vera juice, essential oils of orange, lemon and pomegranate, and mild cleansing agents that make for a full lather, while the conditioner cares for strands with botanical extracts and organic coconut oil.

Each bottle will retail for $17.95, which you can purchase online, or via an Ava Anderson consultant.

Unlike other "earthy" smelling natural hair care products, a crisp, fresh citrus scent permeated our shower while we suds up with the shamnpoo and conditioner, and stayed in our strands long after we blasted our hair with a dryer.

And when you're perusing any kind of haircare that purports to be "natural," Anderson says you need to check the ingredient list and avoid the following words to make sure it's truly legit:

Fragrance. "Manufacturers can legally hide hundreds of ingredients behind that word," Anderson tells StyleList, adding that controversial additives called phthalates are added to the fragrance label 83 percent of the time.

Sodium Lauryl Sulfate (SLS). A harsh detergent that can potentially strip the hair of health and color, SLS is often added to make products lather more. Anderson says SLS has been linked to organ and reproductive toxicity.

Polyethylene Glycol (PEG). Derived from petrolatum, petrochemicals are found in everything from beauty products to laundry detergent to pesticides and plastics, and are added to help preserve products from light and moisture degradation. Anderson says that PEGs in particular have a high toxicity rating, and could be harmful if absorbed by the body.

Parabens. With a long history of controversy, ingredients that end in "paraben" such as methylparaben may be potential carcinogens, with some studies suggesting they may even mutate genes. "Some parabens are banned in Europe, along with 1,300 other banned ingredients total -- while the USA bans roughly 10 ingredients," says Anderson.

As for Anderson's line -- which has now evolved into a direct sales business with consultants operating in 43 states -- the budding entrepreneur says that environmental green issues influenced her creation, just as much as personal safety did.

"Americans put 365 million gallons of shampoo down the drain every year -- and waste water treatment facilities can not remove PPCPs (a term that refers to pollutants caused by pharmaceutical and personal care products) from the water, which is then returned to our water and food supply," says Anderseon.

"Don't put toxic chemicals in your body or down the drain!"

We'll heed your advice, Ms. Anderson.
