Repair & Damage
Strengthening/Protein Treatment
A treatment formulated to support the hair's structure, often used periodically rather than every wash.
What is it?
A protein treatment is a targeted product aimed at hair that feels weak, overly stretchy, or prone to breakage. It's typically applied to clean, damp hair and left on for a set time before rinsing, following the product's specific instructions.
Unlike daily conditioners, protein treatments are usually used less frequently, since overuse can make hair feel stiff or brittle for some people.
What does it typically contain?
Protein treatments often include hydrolyzed proteins such as keratin or wheat protein, sometimes paired with conditioning agents to help offset dryness. Many versions also include moisturizing ingredients to balance the formula.
Protein levels and types differ significantly between brands, so it's worth introducing a new product gradually to see how hair responds.
Formulas differ from brand to brand. Always check the ingredient list on the product you are buying, especially if you have known sensitivities.

When to choose something else
- If your hair feels dry rather than weak, an intensive repair mask is usually the better pick.
- If you want a gentler daily option, a repair conditioner is usually the better pick.
- If you've had recent bleaching or coloring, a bond repair treatment is usually the better pick.
- If breakage is concentrated at the ends, a split-end treatment is usually the better pick.
Frequently asked questions
How often should I use a protein treatment?
This depends on the specific product and your hair's needs, but many people use one every few weeks rather than every wash.
Can too much protein damage hair?
Overuse can make some hair types feel stiff or brittle, so it's generally recommended to alternate with moisturizing products.
Is a protein treatment the same as a bond repair treatment?
They're related but not identical; bond treatments focus on internal bonds, while protein treatments generally focus on rebuilding surface strength.
