Amplified Glow Copper Peptide Strengthening Shampoo – Lavender Review
The lavender shampoo discloses a higher copper peptide concentration than the berry version — 0.15% against 0.1% — and adds keratin, niacinamide, creatine and royal jelly extract to the disclosed ingredient set, while costing $4.00 less. On published information it is the better-specified of the two Amplified Glow shampoos. Two things hold this back from a stronger assessment: the sulfate-free wording is softer than the berry line's, and Amplified Glow's own pages disagree about the bottle size.
Who it fits
Best fit for
- Shoppers comparing the two Amplified Glow shampoos on disclosed peptide concentration.
- People who prefer a lavender scent to a berry scent.
- Anyone who wants keratin and niacinamide disclosed in a shampoo.
Consider another option if
- You want an unqualified sulfate-free claim — the berry line states "Sulfate Free", this one states "Sulfate-Free Surfactants".
- You avoid bee-derived ingredients; this formula discloses royal jelly extract.
- You prefer a berry scent.
What this product is
The Amplified Glow™ Copper Peptide Strengthening Shampoo – Lavender is a rinse-off shampoo. Its own product page states 16 fl oz / 473 mL. Amplified Glow discloses 0.15% GHK-Cu alongside keratin, niacinamide, creatine, sodium hyaluronate, royal jelly extract and lavender extract.
It is one of two scent options Amplified Glow sells in the same product role. The full attribute-by-attribute difference is on our berry versus lavender haircare comparison.
Formula and ingredient context
Amplified Glow states 0.15% GHK-Cu for this shampoo. The berry shampoo states 0.1%. That is a real, published difference between two products in the same range, and it is the clearest formulation distinction the brand discloses anywhere in its haircare line.
The disclosed supporting set also differs. The berry shampoo names sodium hyaluronate, sea kelp extract and rosemary extract. This one names keratin, niacinamide, creatine, sodium hyaluronate, royal jelly extract and lavender extract. Amplified Glow's own FAQ describes the lavender version as "a more advanced strengthening and scalp-supporting formula".
We can report that the lavender formula discloses more named ingredients and a higher peptide percentage. We cannot tell you it works better, and neither can Amplified Glow on the evidence published — no comparative testing is offered for that claim.
Royal jelly extract is a bee-derived ingredient. Amplified Glow makes no vegan claim for this product, and does not address the point either way — worth knowing if you are avoiding animal-derived ingredients.
Routine fit
Amplified Glow directs users to apply to wet hair, massage into a rich lather, rinse thoroughly, and follow with the matching conditioner. That is the standard first wash-day step.
The matching lavender conditioner discloses the same 0.15% GHK-Cu figure. If you are deciding whether to buy the two separately or as the Lavender Glow Hair Stack, our individual products versus bundle comparison works through the arithmetic — including the case where the bundle is not the cheaper option.
On ordering, shampoo and conditioner order covers what the sequence does and does not change.
Price and value context
Listed at $28.00, reduced from $32.00. At the 473 mL figure from its own product page, that is $5.92 per 100 mL at the sale price.
The berry shampoo is $32.00 for the same 473 mL, or $6.77 per 100 mL. So the lavender version is both cheaper and discloses the higher peptide concentration — an unusual combination, and the single most useful fact for anyone choosing between the two on published information alone.
Strengths and limitations
Strengths
- Discloses 0.15% GHK-Cu, the highest published concentration in the Amplified Glow haircare range.
- Cheaper than the berry shampoo while disclosing more named ingredients.
- Names keratin, niacinamide and creatine specifically rather than referring to a complex.
- Clear directions and a stated pairing with the matching conditioner.
Limitations
- The sulfate-free wording is softer than the berry line's and the two are not equivalent.
- Amplified Glow's own pages give two different bottle sizes for this product.
- The full ingredient list is not published as text, so the actual surfactants are unknown.
- No patch-test guidance on this page, unlike the skincare range.
- Royal jelly extract is disclosed without any accompanying vegan or animal-derived note.
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, in particular which surfactants replace sulfates.
- Whether the bottle is 473 mL or 500 mL.
- Which fragrance ingredients create the lavender scent, and whether any are declarable allergens.
- Concentrations for keratin, niacinamide and creatine.
- The source of the disclosed keratin.
Safety and patch-test information
Amplified Glow publishes: for external use only, and avoid contact with eyes. Unlike the skincare range, no patch-test recommendation appears on this page.
If you have a known fragrance sensitivity, the undisclosed fragrance composition is the practical obstacle here. A scented product with no published allergen information cannot be screened from the website.

How much GHK-Cu does the lavender shampoo contain?
Amplified Glow states 0.15%. The berry shampoo states 0.1%.
Is the lavender shampoo sulfate free?
Amplified Glow describes it as made with sulfate-free surfactants. That is a narrower statement than the outright "Sulfate Free" claim used for the berry line, and we report the difference rather than smoothing it over.
Is it cheaper than the berry shampoo?
Yes — $28.00 against $32.00, for the same stated 473 mL volume on each product's own page.
Is it suitable for a vegan routine?
Amplified Glow makes no vegan claim for this product and discloses royal jelly extract, which is bee-derived. We would not describe it as vegan.
How big is the bottle?
It depends which Amplified Glow page you read: the shampoo’s own page says 16 fl oz / 473 mL, while the lavender bundle page says 16.9 fl oz / 500 mL for the same product. We use the shampoo page’s figure and note the difference so you’re aware of it.
Evidence notes
The 0.15% GHK-Cu disclosure, price, scent, disclosed ingredients and directions come from the Amplified Glow lavender shampoo product page, checked on the date shown at the top of this page. The berry comparison figures come from the berry shampoo product page.
The two bottle sizes come from Amplified Glow’s own pages, which disagree with each other. We show both so you can see the discrepancy rather than pick one and present it as settled.

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.
Compare attributes →Product comparisonFragrance-Free vs Scented Cosmetic Products
Two products are explicitly fragrance free: the GHK-Cu + SNAP-8 Peptide Renewal Serum and the Copper Peptide Renewal Serum. Six are explicitly scented — the four haircare items and the muscle rub name their scents, and the bundles inherit them. The rest say nothing about fragrance either way, and that silence shouldn’t be read as a fragrance-free claim.

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.

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.
