Amplified Glow Copper Peptide Nourishing Conditioner – Berry Review
The berry conditioner discloses keratin, niacinamide, panthenol and 0.1% GHK-Cu at $32.00 for 473 mL. The most useful thing to know before buying is a documentation problem rather than a formula one: the standalone product page gives shampoo directions for a conditioner. Follow the instructions on the bundle page instead.
Who it fits
Best fit for
- Anyone using the matching berry shampoo who wants the paired conditioner.
- Shoppers who want keratin and niacinamide disclosed by name.
- People who prefer a berry scent.
Consider another option if
- You want the higher disclosed peptide concentration — the lavender conditioner publishes 0.15% for $28.00.
- You want squalane in the disclosed ingredient set; the lavender version has it and this one does not.
- You are buying both wash-day steps, in which case the bundle is cheaper.
What this product is
The Amplified Glow™ Copper Peptide Nourishing Conditioner – Berry is a 473 mL rinse-off conditioner. Amplified Glow discloses 0.1% GHK-Cu alongside keratin, niacinamide, panthenol, sodium hyaluronate, rosemary extract and green tea extract.
Formula and ingredient context
The disclosed conditioning set is more substantial than the matching shampoo's: keratin, niacinamide and panthenol are all named, where the berry shampoo names only sodium hyaluronate, sea kelp and rosemary.
Amplified Glow does not specify the source of the disclosed keratin, which can be derived from several origins. That matters to anyone avoiding animal-derived ingredients, and the brand makes no vegan claim for this product.
The claimed free-from set is sulfate free, paraben free, dye free and silicone free. Silicone-free is a more meaningful statement for a conditioner than for a shampoo, since silicones are common conditioning agents — it tells you the slip is coming from something else, though not from what.
Routine fit
Used as the second wash-day step after the matching shampoo, this is a conventional rinse-out conditioner. Shampoo and conditioner order covers the sequence.
Price and value context
Listed at $32.00, reduced from $37.00. At 473 mL that is $6.77 per 100 mL at the sale price.
The lavender conditioner is $28.00 for 500 mL, which is $5.60 per 100 mL — about 17% less per millilitre, with a higher disclosed peptide concentration and squalane added to the disclosed set.
Bought with the matching shampoo as The Glow Hair Stack, the pair is $58.00 rather than $64.00.

How should I actually use this conditioner?
Apply after shampooing, focusing on mid-lengths to ends, leave in for 2–3 minutes, then rinse thoroughly. That is the instruction on the bundle page. The standalone page describes lathering, which we believe is an error.
How much GHK-Cu does it contain?
Amplified Glow states 0.1%. The lavender conditioner states 0.15%.
Is the keratin animal-derived?
Amplified Glow does not say. The brand makes no vegan claim for this product.

Berry vs Lavender Amplified Glow Haircare
More than the scent. The lavender line discloses 0.15% GHK-Cu against the berry line's 0.1%, names more supporting ingredients, and costs less — $28.00 per bottle against $32.00. The berry line makes the clearer free-from claims, stating "Sulfate Free" outright where the lavender line states "Sulfate-Free Surfactants". If you have no scent preference, the lavender line is better specified for less money.
Compare attributes →Product comparisonIndividual Products vs a Haircare Bundle
At current sale prices, the bundle. The berry duo saves $6.00 against $64.00 for the pair, and the lavender duo saves $4.00 against $56.00. At regular prices the berry bundle saves nothing — its $74.00 regular price is exactly the sum of the two components. The saving comes from the bundle's deeper promotional discount, not from bundling itself, so the arithmetic needs redoing whenever prices change.

GHK-Cu
GHK-Cu is a small peptide complexed with copper. In cosmetics it appears under the INCI name Copper Tripeptide-1 and is used as a conditioning ingredient. It is the ingredient every Amplified Glow copper peptide product is built around, and the only one for which the brand publishes concentrations — between 0.1% and 0.15% depending on the product.
Read the ingredient page →Structural protein, or a hydrolysed fraction of oneKeratin
"Keratin" on a label isn’t a single ingredient. Several versions exist — hydrolyzed keratin, keratin amino acids, and others — differing in source and size. Amplified Glow names keratin in four haircare products without saying which form or source, so the exact ingredient isn’t confirmed.
Read the ingredient page →Vitamin B3 amideNiacinamide
Niacinamide is the amide form of vitamin B3, used widely in cosmetics as a conditioning and smoothing ingredient. Amplified Glow discloses it in four products — one face cream and three haircare items — and publishes no concentration for any of them.
Read the ingredient page →Provitamin B5 alcoholPanthenol
Panthenol, often labelled pro-vitamin B5, is used in cosmetics as a humectant and conditioning agent. It appears in four Amplified Glow products across skincare and haircare. No concentration is published for any of them.

Shampoo and conditioner order
Shampoo first, conditioner second. Shampoo cleanses the scalp and lifts buildup; conditioner is applied to mid-lengths and ends afterwards and left for a couple of minutes before rinsing. The order matters because the two products do opposite things — cleansing removes, conditioning deposits — and doing them the other way round removes what you just deposited.
Read the guide →GuideWhat “not disclosed” means in a product comparison
Not disclosed means the brand does not publish it. Not verified means a value may exist but we have not confirmed it. Brand disclosed means the brand states it and we are reporting that accurately without independently confirming it. None of these means zero, and none of them is filled with an estimate — a table with honest blanks is more useful than one with invented numbers.
