Hydrolyzed and non-hydrolyzed proteins are both used in hair care, but they function differently due to their molecular size and ability to penetrate the hair shaft. Understanding the differences between these two types of proteins can help you determine when your hair needs one over the other.
Hydrolyzed Proteins
Definition – Hydrolyzed proteins are proteins that have been broken down into smaller peptides or amino acids through a process called hydrolysis. This process reduces the protein’s molecular size, making it easier for the hair to absorb.
Benefits
Improved Penetration Due to their smaller size, hydrolyzed proteins can penetrate the hair shaft more effectively, delivering nutrients and moisture deep within the hair.
Strengthening and Repair. Help rebuild the hair’s internal structure, strengthen damaged hair, and reduce breakage.
Moisture Retention. Helps the hair retain moisture, making it softer and less prone to frizz.
Common Types – Hydrolyzed keratin, hydrolyzed silk, hydrolyzed wheat, and hydrolyzed collagen.
Non-Hydrolyzed Proteins
Definition Non-hydrolyzed proteins are whole, intact proteins that have not been broken down into smaller fragments. They have a larger molecular size and do not penetrate the hair shaft as effectively as hydrolyzed proteins.
Benefits
Film-Forming Coat the surface of the hair shaft, providing a protective barrier that can help lock in moisture and prevent environmental damage.
Adds Volume and Shine : Can help make hair appear fuller and shinier by coating each strand.
Offers temporary strengthening effects by adhering to the hair surface.
Common Types : Whole keratin, collagen, milk proteins, and oat proteins.
When Does Hair Need Hydrolyzed Proteins?
Use Hydrolyzed Proteins When :
Hair Is Damaged or Weak : Ideal for hair that has been chemically treated, over-processed, or exposed to excessive heat styling. Hydrolyzed proteins help repair the hair shaft from the inside out.
Hair Lacks Elasticity : Hair that stretches too much without returning to its original state or breaks easily needs hydrolyzed proteins to rebuild strength and elasticity.
: Hydrolyzed proteins can strengthen and add volume to fine or thinning hair without weighing it down.
Moisture-Depleted Hair ; Hydrolyzed proteins can help hair retain moisture by penetrating deep into the hair shaft and repairing any damage that causes moisture loss.
When Does Hair Need Non-Hydrolyzed Proteins?
Use Non-Hydrolyzed Proteins When:
Hair Needs Protection. : Non-hydrolyzed proteins form a protective film around the hair shaft, shielding it from external damage caused by environmental stressors, UV rays, or pollution.
Hair Needs Smoothness and Shine : Non-hydrolyzed proteins coat the hair’s surface, smoothing the cuticle, reducing frizz, and enhancing shine.
Voluminous Hair with Minimal Damage : If the hair is already healthy but needs more body or a fuller appearance, non-hydrolyzed proteins can help add volume and thickness.
Moisture Retention on the Surface : For hair that needs surface moisture without heavy penetration, non-hydrolyzed proteins can lock in hydration by forming a barrier on the hair’s exterior.
How to Determine Which Type of Protein Your Hair Needs
Assess the Condition of Your Hair:
If your hair feels weak, is breaking, or has been exposed to chemical treatments or heat damage, opt for hydrolyzed proteins. to help repair and strengthen it from the inside.
If your hair feels healthy but looks dull, frizzy, or lacks volume, consider using **non-hydrolyzed proteins** to enhance shine, smoothness, and fullness.
Test Your Hair’s Elasticity :
Take a single strand of hair and gently stretch it:
If it breaks quickly, you may need -hydrolyzed proteins, to improve its strength and elasticity.
If it stretches and returns to its shape but lacks shine or feels rough, -non-hydrolyzed proteins, can help add smoothness and shine.
