Key Features and Benefits:

Frizz Control: The main benefit of this conditioner is its ability to tame frizz and fly-aways. When used with the accompanying shampoo, it can provide up to 72 hours of frizz control.

Key Ingredients: The formula is typically infused with Keratin Protein and Marula Oil (or sometimes Argan Oil, depending on the specific product line and region). Keratin is a protein that is a natural building block of hair, and Marula or Argan oil adds a lightweight, nourishing element to boost shine and softness.

Five Benefits in One: The TRESemmé Keratin Smooth system is often marketed as delivering five benefits in one wash:

Fights frizz.

Detangles knots.

Adds shine.

Adds softness.

Tames fly-aways.

Suitable for Various Hair Types: While it's particularly effective for dry, frizzy, and unruly hair, it can be used on all hair types. It is also safe for use on color-treated hair.

Lower Sulfate Formulation: The product is often formulated with a lower sulfate content, which helps to preserve the hair's natural moisture and is gentler on the scalp.
