Collagen & Keratin Hair Mask

Dewly's Collagen & Keratin Hair Mask is a weekly treatment built for hair that feels dry, brittle, or worn down from styling and everyday water exposure. Collagen peptides and hydrolyzed keratin are formulated to help reinforce the hair's outer layer, supporting smoother texture and a healthier look over time. It is a straightforward addition to a water-wellness routine, working alongside a shower filter rather than replacing the need for one."

How it works

Apply a generous amount to clean, towel-dried hair from mid-length to ends, focusing on areas that feel dry or brittle. Leave on for 5 to 10 minutes, allowing the collagen and keratin peptides to work into the outer layer of each strand, then rinse thoroughly. Use once or twice a week, or more often on hair that sees frequent heat styling or sun exposure.

Good to know

• Collagen peptides and hydrolyzed keratin work to help replenish the protein structure of each strand, targeting rough, damaged patches left by heat styling or hard water exposure
• Lightweight formula coats hair without heavy buildup, so strands feel smoother and appear more defined from root to end after a few uses
• Concentrated cream absorbs into the hair shaft during the recommended 5 to 10 minute treatment, rather than sitting on top like a rinse-out conditioner
• Pairs well with a shower filter routine: reducing chlorine and mineral buildup on strands beforehand gives the mask fewer residues to work around
• Free of sulfates and silicones that can weigh hair down or mask (rather than repair) surface damage over time
