It looks like you're referring to a keratin-based shampoo, likely in a 900ml bottle. Keratin shampoos are popular for repairing and strengthening hair, especially for damaged, frizzy, or chemically treated hair. Here’s what you might want to know:

Key Features of Keratin Shampoo:

Repairs & Strengthens – Keratin fills in gaps in the hair cuticle, reducing breakage.

Smooths & Reduces Frizz – Helps tame unruly hair and adds shine.

Restores Moisture – Good for dry, brittle hair.

Protects from Heat & Damage – Often used after coloring, bleaching, or heat styling.

Popular Keratin Shampoo Brands (900ml Size):

OGX Keratin Oil Shampoo

Tresemmé Keratin Smooth Shampoo

L'Oréal Paris Elvive Total Repair 5 (with Keratin)

Schwarzkopf Gliss Keratin Repair Shampoo

Things to Consider:

Sulfate-Free? Better for color-treated hair.

For Daily Use? Some keratin shampoos are heavy, so check if it's suitable for frequent use.

Protein Sensitivity? If your hair gets stiff/brittle with protein, balance with moisturizing conditioners.
