Vitamin B3 amide
Niacinamide
Formula context
Niacinamide is water-soluble and stable across a wide pH range, which makes it straightforward to formulate with. That is part of why it appears in so many products across the cosmetic category.
In the Amplified Glow range it appears in two quite different contexts. In the Men's Blue Peptide Face Cream it is a leave-on skincare ingredient. In the lavender shampoo and both conditioners it is in rinse-off haircare, where Amplified Glow describes it as supporting the scalp and healthier-looking hair.
Those two contexts are not equivalent, and evidence about one does not transfer to the other. A leave-on facial product and a two-minute rinse-off conditioner deliver an ingredient completely differently.
What the evidence can and cannot establish
Niacinamide is comparatively well studied for topical cosmetic use. As with any ingredient, though, that research doesn’t tell you what a specific product will do — especially when the amount used isn’t published.
The rinse-off applications need particular care. Most of what is discussed about topical niacinamide concerns leave-on products. Extending those discussions to a shampoo is not supported by the shampoo containing the same ingredient.
Claim limitations
- No Amplified Glow product publishes a niacinamide concentration.
- Evidence for leave-on facial products does not establish outcomes for rinse-off haircare.
- Nothing here claims niacinamide treats any skin or scalp condition.
- "Supports healthier-looking hair" is an appearance claim, and we do not extend it into a claim about hair or scalp biology.
Sensitivity considerations
Amplified Glow publishes no ingredient-specific sensitivity information for niacinamide. Its general leave-on patch-test guidance applies to the finished product.
Common formulation companions
- GHK-Cu, in all four Amplified Glow products disclosing niacinamide
- Keratin and panthenol in the haircare formulas
- Sodium hyaluronate
Amplified Glow products that disclose niacinamide
Copper Peptide Nourishing Conditioner – Berry
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.
Copper Peptide Strengthening Shampoo – Lavender
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.
Copper Peptide Nourishing Conditioner – Lavender
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.

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.

An INCI list orders ingredients by concentration down to 1%, after which order means nothing. Marketing names and INCI names are different systems — SNAP-8 is a trade name and will appear on a panel as something else. The most useful skill is recognising what a list does not tell you: exact percentages, molecular weights, and the composition of anything labelled "extract" or "fragrance".
