Collection: Hair Protein

Professional Hair Protein Treatments

Hair is protein. When that protein breaks down, everything breaks down with it.

Heat styling, bleach, chemical processing, and everyday stress deplete the keratin and amino acids that give your hair its strength, elasticity, and structure. Once the protein is gone, no amount of conditioning will bring it back. You need to rebuild from within.

BRUSH's Hair Protein collection delivers exactly that. Our professional-grade protein treatments are formulated with hydrolyzed keratin and concentrated amino acid complexes that penetrate deep into the cortex, rebuilding the structural bonds that damage has broken. The result is measurably stronger, more elastic hair with significantly less breakage, improved texture, and a healthy, natural shine.

Who Needs a Protein Treatment?

Your hair is telling you it needs protein if you notice: excessive breakage or shedding, hair that feels mushy or overly stretchy when wet, loss of elasticity and bounce, persistent dullness despite conditioning, or hair that has been bleached, colored, or chemically straightened.

Key Ingredients

Hydrolyzed Keratin — Penetrates the cortex to rebuild broken disulfide bonds and restore tensile strength.
Amino Acid Complex — Replenishes the protein building blocks depleted by chemical and thermal damage.
Panthenol (Pro-Vitamin B5) — Improves flexibility and softness, reducing breakage at the most vulnerable points.
Ceramides — Seal the cuticle after treatment to lock in the repair and prevent moisture loss.

How to Use

Apply to clean, damp hair after shampooing. Leave on for 10–15 minutes — use gentle heat for deeper penetration. Rinse thoroughly and follow with a lightweight conditioner or serum. Use once a week for maintenance, or twice a week for severely damaged hair.

All BRUSH protein treatments are color-safe, sulfate-free, and suitable for all hair types including chemically processed and color-treated hair.
