Amplified Glow Copper Peptide Nourishing Conditioner – Lavender Review

Last reviewed Last fact-checked
Our verdictModerate documentation

On published specification this is the best-value conditioner Amplified Glow sells: 500 mL for $28.00 is $5.60 per 100 mL, the cheapest in the range, with the highest disclosed peptide concentration at 0.15% and the longest disclosed ingredient set. It is also the only Amplified Glow haircare product that is unambiguously larger than its counterparts — 500 mL against 473 mL.

Who it fits

Best fit for

  • Shoppers choosing a conditioner on disclosed concentration and price per millilitre.
  • People who prefer a lavender scent.
  • Anyone who wants squalane and keratin both disclosed.

Consider another option if

  • You prefer a berry scent.
  • You want an unqualified sulfate-free claim rather than a surfactant-system description.
  • You are buying both wash-day steps, where the Lavender Glow Hair Stack applies.

What this product is

The Amplified Glow™ Copper Peptide Nourishing Conditioner – Lavender is a 500 mL rinse-off conditioner. Amplified Glow discloses 0.15% GHK-Cu alongside keratin, niacinamide, panthenol, squalane, creatine, sodium hyaluronate, aloe vera and lavender extract.

At nine named ingredients it has the longest disclosed hero list in the Amplified Glow haircare range.

Formula and ingredient context

Squalane is the notable addition relative to the berry conditioner. It is a well-characterised emollient with a clear cosmetic role, and it is the kind of ingredient whose presence tells you something concrete about how a formula is built. Our squalane page covers what it does and what it does not.

Creatine also appears here and in the lavender shampoo, and nowhere else in the range. Amplified Glow describes it as supporting the feel of strength and manageability. That is a sensory description rather than a measured outcome, and we would not present it as more than that.

The free-from claims are "Sulfate-Free Surfactants" and "Paraben Free" — the same softer sulfate wording used across the lavender line.

Routine fit

Amplified Glow directs users to apply after shampooing, focusing on mid-lengths to ends, leave in for 2–3 minutes, then rinse thoroughly. Unlike the berry conditioner page, these directions are correct for a conditioner.

Paired with the lavender shampoo, both products disclose 0.15% GHK-Cu.

Price and value context

Listed at $28.00, reduced from $32.00. At 500 mL that is $5.60 per 100 mL at the sale price — the lowest of any Amplified Glow haircare product.

The berry conditioner is $32.00 for 473 mL, or $6.77 per 100 mL. So the lavender conditioner is cheaper in absolute terms, larger, and discloses a higher peptide concentration.

Strengths and limitations

Strengths

  • The lowest price per 100 mL in the Amplified Glow haircare range.
  • The highest disclosed copper peptide concentration in the range, at 0.15%.
  • The longest disclosed hero ingredient list of any Amplified Glow haircare product.
  • Correct, conditioner-specific directions.
  • Largest bottle in the haircare range at 500 mL.

Limitations

  • The sulfate-free wording is qualified rather than absolute.
  • The full ingredient list is not published as text.
  • No patch-test guidance.
  • Keratin source is not specified.
  • Amplified Glow's bundle page states a different volume for the paired shampoo, which undermines confidence in the range's size disclosures generally.

What we could not establish

Amplified Glow does not publish these, and we have not confirmed them. We record them as open questions rather than guessing.

  • Full INCI list.
  • The source of the disclosed keratin.
  • Concentrations for squalane, creatine and keratin.
  • Fragrance composition.

Safety and patch-test information

Amplified Glow publishes: for external use only, and avoid contact with eyes.

Frequently asked questions

Is this the cheapest Amplified Glow conditioner?

Yes, both in absolute terms ($28.00 against $32.00) and per millilitre ($5.60 against $6.77 per 100 mL).

How much GHK-Cu does it contain?

Amplified Glow states 0.15%, the highest disclosed figure in its haircare range.

What does squalane do here?

It is an emollient. In a rinse-off conditioner it contributes to how the product conditions and to the feel of the hair afterwards. Amplified Glow does not publish its concentration.
