Keratin Treatments

Our keratin treatments collection is formulated to strengthen, smooth and repair hair that has been damaged by heat styling, colouring, bleaching or environmental stress. Keratin-infused products help replenish lost proteins, minimise frizz and improve shine, leaving the hair noticeably healthier and easier to manage. They work particularly well alongside restorative products such as hair repair treatments.

What Are Keratin Treatments?

Keratin treatments are specialised haircare products that restore the natural protein structure of the hair. These formulas may include hydrolysed keratin, amino acids and strengthening polymers that help reinforce weakened fibres. Keratin is the primary structural component of hair, and replenishing it can help improve elasticity, smoothness and resistance to breakage. These treatments are popular among individuals with frizzy, dry, coarse or chemically treated hair.

Benefits and Features of the Welzo Keratin Treatments Collection

• Strengthens damaged hair: Helps reinforce weakened areas of the fibre.
• Reduces frizz: Smooths the cuticle for a more polished appearance.
• Improves elasticity: Makes hair more resilient during brushing and styling.
• Enhances shine: Creates a smoother surface for better light reflection.
• Restores softness: Nourishing formulas improve manageability.
• Ideal for chemically processed hair: Suitable for coloured, bleached or permed hair.

Why Are Keratin Treatments Important?

Heat styling, chemical straightening, bleaching and frequent colouring all weaken the hair’s natural keratin structure. Over time, this causes breakage, frizz, dryness and a rougher texture. Keratin treatments help replenish essential proteins, restoring hair strength and smoothness while improving long-term resilience. They are especially effective when paired with protective products such as conditioners and heat-protective styling products.

How to Use Keratin Treatments

• Apply to clean, damp hair after washing.
• Distribute evenly from mid-lengths to ends.
• Leave on for the recommended time before rinsing (for masks).
• Use leave-in keratin serums on towel-dried hair before styling.
• Limit heat exposure where possible, or always use a heat protectant.

Expert Insights, Research & Statistics on Keratin Hair Repair

Keratin and protein-based treatments are widely supported by cosmetic-science research due to their ability to improve hair fibre strength and smoothness. Key findings include:

• Hydrolysed keratin helps temporarily fill gaps in the hair cuticle.
• Protein-rich treatments can improve tensile strength in damaged hair fibres.
• Keratin formulas may reduce frizz and enhance shine through cuticle alignment.
• Amino acid blends support elasticity and reduce snapping during brushing.
• Regular use can improve the overall softness and texture of processed hair.

Haircare professionals often recommend alternating between protein-based treatments and moisturising products to maintain balance and avoid over-strengthening.
