Proteins are large molecules consisting of amino acids that keep our bodies functioning properly. They play a pivotal role in virtually every biological process, including our hair. Hair is made up of one extremely strong protein called keratin and while keratin may be strong, manipulation and environmental elements damage it over time. Pollutants, wind, sun, heat styling, permanent hair color, chemical-straightening treatments, and standard maintenance all contribute to the breaking down the keratin in our hair strands. This is where protein treatments come to restore our strands. 

All protein treatments are not created equal, as some are potent while others are mild. Oftentimes proteins in treatments and conditioners will include hydrolyzed wheat protein, hydrolyzed silk protein, hydrolyzed soy protein, hydrolyzed milk protein, hydrolyzed keratin protein, and hydrolyzed collagen protein. Stronger protein treatments have higher concentrations of proteins, which when used too often can make your hair dry, brittle, and straw like. These proteins are intended to strengthen the hair’s cuticle layer by filling in chips along the shaft. They are not intended to condition and soften the hair. If you are looking for strictly protein, we’ve got you covered.

Greek yogurt

Greek yogurt has taken dairy lovers and health enthusiasts by storm. Greek yogurt has double the protein of regular yogurt and people love to eat if for the taste too. While you can find Greek yogurt in tons of hair recipes from masks to conditioners, those recipes are using the goodness of Greek yogurt for the power punch in protein and nutrients and not for conditioning.


Gelatin is a colorless, odorless, translucent, and tasteless water-soluble protein made from collagen. Largely composed of amino acids, glycine and proline, gelatin is an irreversible hydrolyzed form of collagen. It is perfect for adding protein to strengthen your hair and nails, but it has no conditioning qualities. Just like with Greek yogurt, when you see it in conditioners or in DIY hair recipes, it is being used for its protein power only.

ApHogee Two-Step Protein Treatment

Another growing favorite, this REAL Protein treatment is pure hydrolyzed wheat protein.

ApHogee Keratin 2 Minute Reconstructor

Protein treatments are intended to make your hair less porous. Both too much and too little protein cause dryness. Too much protein will not allow moisture to penetrate and too little will make it difficult for your hair to retain moisture.  Balance is key. Still confused?
