Step 1: Match the Protein to the Goal. Keratin and wheat protein strengthen and repair, silk and rice add softness and shine, and lighter proteins like silk suit fine hair. For skin, proteins bind moisture and form a smooth film. Start with the result you want.

Step 2: Choose Vegan or Not. Keratin, silk, egg, milk, and pearl are animal-derived. Wheat, corn, rice, oat, soy, pea, and lupine proteins are plant-based, so reach for those for a vegan formula. Both types condition well.

Step 3: Add to the Water Phase, Low. Hydrolyzed proteins are water-soluble and go into the water phase, usually during the cool-down. Use them at a small percentage, since a little does the work and too much causes stiffness. Follow the listing's level.

Step 4: Balance and Preserve. Pair protein with moisture and slip so hair stays soft, not brittle. Preserve any water-based product with a broad-spectrum preservative, and patch test the finished formula.
About Hydrolyzed Proteins
A hydrolyzed protein is a full protein broken down into small pieces, amino acids and short peptides, small enough to reach into the hair shaft and bind to the surface of skin. In hair care, that is what lets them do real work: hydrolyzed keratin fills the gaps in damaged hair and can noticeably improve strength, hydrolyzed wheat protein adds elasticity and holds moisture, and silk and rice proteins leave hair soft and shiny. Lighter proteins like silk and wheat suit fine hair because they strengthen without weighing it down, while damaged or chemically treated hair benefits from more intensive keratin. On skin, these proteins bind moisture and form a smooth, conditioning film.
The range here spans animal and plant sources so you can match your claims. Keratin, silk, egg, milk, and pearl proteins are animal-derived, while wheat, corn, rice, oat, soy, pea, and lupine are vegan. The one rule everyone learns is balance: too much protein without enough moisture leaves hair stiff and brittle, a state called protein overload. Every protein here is INCI-named with a use level, made in a WHO-GMP and ISO 9001:2015 certified facility with a COA on request.
Good to Know
• Match the protein to the hair. Fine hair likes light proteins like silk and wheat; damaged or color-treated hair likes intensive keratin. The right protein depends on what the hair needs.
• Balance protein with moisture. Too much protein without enough moisture leaves hair stiff and prone to breakage. Pair protein with humectants and conditioning slip, and do not overdose it.
• Add low, in the cool-down. Proteins are water-soluble and go into the cooled water phase at a small percentage. Any water-based product needs a broad-spectrum preservative; ask for the COA on your batch.
Frequently Asked Questions
Hydrolyzed protein is a protein broken into small amino acids and peptides, small enough to reach into the hair shaft. There it helps fill gaps in damaged strands, add strength and elasticity, and improve softness and shine. It is used in shampoos, conditioners, masks, and leave-ins, and different sources give slightly different benefits.
It depends on the hair. Hydrolyzed keratin is best for damaged and chemically treated hair because it repairs and strengthens. Hydrolyzed wheat protein adds elasticity and moisture, and silk and rice proteins add softness and shine. For fine hair, lighter proteins like silk and wheat strengthen without weighing it down.
Choose keratin for repair and strength on damaged or over-processed hair, since it fills gaps in the cuticle and improves tensile strength. Choose wheat protein, a vegan option, for elasticity and moisture retention, especially on fine hair. Many products use more than one protein to get both benefits.
Hydrolyzed proteins are water-soluble, so they go into the water phase of a formula, usually during the cool-down, at a small percentage. In a finished product, apply to clean, damp hair, focus on the mid-lengths and ends, leave a mask on for the recommended time, then rinse. Keep the level low to avoid stiffness.
Protein overload is when hair gets too much protein and not enough moisture, which leaves it stiff, dry, and prone to breakage rather than strong and healthy. It is fixed by easing off protein and adding moisture and slip. The lesson for formulating is to use protein at a low level and balance it with humectants and conditioning.
Yes. Wheat, corn, rice, oat, soy, pea, and lupine proteins are all plant-based and vegan, and they condition and strengthen hair well. Keratin, silk, egg, milk, and pearl proteins are animal-derived. For a fully vegan formula, choose from the plant-based options, several of which perform comparably to keratin.
Yes. On skin, hydrolyzed proteins like silk bind moisture and form a light, smooth film that leaves skin feeling conditioned and soft. They appear in serums, creams, and lightweight moisturizers. As with hair, they are used at a low level in the water phase, and the finished product needs preserving.
