With a sea of options and an ever-growing demand of “clean” ingredients, Alterna made its mark among the pioneers in “free of” harsh chemicals and additives in the high-end market.

Only natural eco-certified ingredients. No sulfates or parabens. No animal testing. Ever.

Yes all Alterna products are free of added SLS/SLES: Sodium Lauryl Sulfate/Sodium Laureth Sulfate.

Alterna's ingredients are eco-certified and sustainably harvested to help maintain the environment. They're also free of sulfates, parabens, synthetic dyes and gluten, and they are not tested on animals. Every Alterna product is considered color-safe, so you'll never have to compromise on your time spent at the salon.

Are Alterna products gluten free? We do not include gluten in our formulations but we do not test after formulation for gluten so there could be trace amounts in our formulas due to cross-contamination during manufacturing.

Alterna Caviar Anti-Aging Bond Repair Leave-In Protein Cream is a deeply restorative, protein-packed leave-in treatment for coarse, porous, damaged hair.

It is naturally luxurious and rich in vitamins, minerals, and omega fatty acids that help restore hair's lipid layer to its optimal state—the key to healthier, younger-looking hair.

The resulting collection turned out to be such a worthy Bamboo successor that we've decided to sunset the Bamboo line and focus exclusively on our Caviar and My Hair My Canvas collections.

Yes, all our shampoos are safe for keratin treatements as we are free of added SLS/SLES.

“The Pro hair Caviar plus protein Treatment” reduces the stiffness (elastic modulus) in the hair, this reduction or softening effect causes the hair to lose its natural curl and feel softer. The greater the concentration along with application of caviar protein& Argan oil, the softer or straighter the hair will become.

What Is A Protein Treatment And What Does It Do? Protein treatments are formulated to create a layer of protection for your hair. They fill any holes or gaps within the hair's cuticle which can be damaged from a variety of factors including heat styling, hair color, or constant manipulation.

So how can you tell if you need moisture or protein? The simplest option is to take a wet or dry strand of hair and gently stretch it. If it barely stretches and snaps, you need more moisture and might have too much protein. Also, if you brush your hair and strands fall out, you need protein.
