Spa Line Protein Brazilian Keratin Serum

The Spa Line Protein Brazilian Keratin Serum is a specialized hair treatment designed to nourish and strengthen hair, particularly beneficial for those with chemically treated or damaged hair. It typically contains keratin, a protein that helps repair and rebuild the hair structure, leaving it smoother, softer, and more manageable. This serum is often applied after shampooing and conditioning, and it works by coating the hair shaft to protect it from environmental damage while providing hydration and improving elasticity. Regular use of this serum can help restore the health and vitality of hair, leaving it looking healthier and more radiant.
