Cosmo Keratin Serum 100ml

100ml

Restore and seal damaged hair with Cosmo Keratin Serum. This concentrated 100ml formula penetrates deep into the hair shaft, reconstructing weakened strands and sealing the cuticle for a smooth, lustrous finish. Infused with keratin, it repairs breakage, reduces frizz, and restores elasticity—leaving your hair visibly healthier and more resilient. Ideal for color-treated, heat-damaged, or chemically processed hair. Apply to damp hair, focusing on mid-lengths and ends, for transformative results with every use.
