Keratin, Argan Oil, Collagen, & Vegetable Protein: What Can They Do for Your Hair?

Have you been suffering from dry, damaged, or over-processed hair? If so, you may want to continue reading. Below are some of the best ingredients you should be looking for in your hair products if you're going to combat weak, dehydrated hair. Number four is one of our little secrets…


Keratin is one of the critical structural components of the hair. It’s a natural protein that protects the cuticle and the hair’s inner core, so when your hair gets abused by heat, chemicals, and other environmental factors, the natural keratin gets depleted and needs a little help. If you hate the look of dull, dry, and frizzy hair, then get hair products with keratin. What can keratin-infused products do for your hair? For starters, they replenish the natural keratin that your hair has lost and fill in cracks along damaged areas in the hair shaft working to heal the hair from the inside out. It also coats the outside of the hair to form a shield that protects from harmful pollutants. Overall, keratin will increase the moisture in the hair restoring lost luster and shine.

Argan Oil

Argan oil is considered “liquid gold” in many cultures because it’s packed with rich nutrients such as vitamin A, vitamin E, Omega-6, and linoleic acid. This miracle oil is an excellent moisturizer for your scalp and hair and can help improve blood circulation to the scalp resulting in healthier hair growth. Just ran out of your favorite heat protectant? Argan oil protects against hot styling tools while fighting against frizz and split ends.


Collagen makes up 1/3 of the protein found in your body, so it’s no surprise that we get wrinkles when collagen levels begin to decline. The same goes for your hair. When collagen concentrations in the hair are weak, it can appear lifeless and brittle, and you’re more prone to breakage and hair loss. Hydrolyzed collagen found in many hair care products can assist in rebuilding the hair’s lost protein and supports healthier growth for longer, fuller hair. Just like Argan oil, collagen is an excellent way to promote healthy moisture levels in the hair to maintain strength and elasticity.

Vegetable Protein

For strong, fade-resistant hair there’s a secret ingredient that you should be looking for in your hair products—vegetable protein. After severe chemical or heat damage, vegetable protein can help fill in the empty gaps that are present along the hair shaft. Unlike animal protein, veggie protein will not leave a filmy residue, so you’ll get soft, silky hair with a radiant shine. Its similarity to human hair’s chemical structure allows for easier absorption and a long-lasting effect. Vegetable protein provides an overall restructuring and strengthening effect to the hair, so next time you’re in the shampoo aisle, look out for this magical ingredient.

Just as you should be educating yourself about harmful ingredients in hair products, you should also be researching quality ingredients that will work to repair your hair. While an individual product may work for one type of hair, it might not work for another. How many times has someone told you that this one shampoo was the “holy grail” of shampoos, only for you to try it and find out it doesn’t do anything? In this case, argan oil, keratin, collagen, and vegetable protein all work together to repair and provide the hair with moisture replenishing qualities. If you need volume and texture, you’ll want to consider ingredients like vitamin B5 [panthenol] or wheat proteins and if you want maximum shine, consider seaweed and lotus blossom. As always, do your research and find what ingredients will work best for your hair problems.
