Category rating — not an assessment of any specific brand
This rating covers a typical, mass-market
personal care product based on publicly available data.
It does not name or assess any specific manufacturer or product.
Individual products may perform better or worse.

What this score means
The score shown is the current market baseline for personal care — what the HIP methodology can confirm from
publicly available specification data alone, before any manufacturer evidence is reviewed. The category ceiling
shown in small text below the score is what the methodology rewards when materials, supply chain, repairability,
and end-of-life pathways are fully evidenced. Manufacturers close that gap by applying for verified assessment.
Manufacturer? Verified assessment closes the gap.
The current market baseline for this category is 2.7 HIP.
The category ceiling — what the methodology rewards when materials, supply chain, repairability, and end-of-life
pathways are fully evidenced — is 7.3 HIP.
The first verified product in our programme demonstrated 6.9 HIP and earned the HIP Mark.
If your product can evidence the methodology dimensions, verified assessment gives it the score it has earned.

Score Breakdown
Material Scarcity Index
20% weight
3.5
The product contains copper and ABS plastic, which are not critical, but the absence of disclosed recycled content (0%) and the high likelihood of single-country supply concentration for copper and rare earth elements in heating elements drive a conservative score. The lack of data on extraction origins prevents confirming supply diversity, necessitating a penalty for potential scarcity risks.
Supply Chain Risk
18% weight
3.5
The hair straightener relies on copper and nichrome heating elements, which face moderate concentration risks as China dominates global supply for these materials. Due to the lack of submitted due diligence standards, alternative suppliers, or audit verification, the score reflects a high-risk profile typical for generic consumer electronics manufactured in China without transparency.
Recyclability & Circularity
18% weight
2.0
The hair straightener is assumed to be glued with no take-back scheme, rendering material separation impractical. Only a small fraction of metal components are theoretically recoverable, while the ABS plastic housing and nichrome heating elements are routinely landfilled in practice. This aligns with the non-recyclable baseline for sealed consumer electronics lacking disassembly features.
Repairability
13% weight
2.0
The hair straightener is assumed to be glued shut with no spare parts available and no public service manual, classifying it as unrepairable. As a mass-market small appliance outside EU Ecodesign scope, it is designed for replacement rather than repair.
Social & Environmental Impact
8% weight
3.5
The product is manufactured in China, a moderate-to-high risk jurisdiction for labour and environmental issues, with no submitted evidence of third-party audits or certifications. While ILO compliance is not claimed, the absence of an RBA audit, ISO 14001, or a modern slavery statement prevents the score from reaching baseline compliance levels.
Product Longevity
8% weight
3.5
The product receives a below-average score due to a 2-year warranty and a stated design life of only 4 years, which falls short of the typical 5-7 year lifespan for hair straighteners. The lack of an IP rating and modular design further limits its longevity potential, placing it in the mass-market category.
Regenerative Index
15% weight · scale −10 to +10
-7.0
The product is scored as Depleting (-7) because it is a conventional hair straightener with zero recycled content, no take-back scheme, and no regenerative certifications. Not Depleting because recycled content >= 50% with verified take-back does not apply; the product relies on virgin mined materials with no pathway toward regeneration.

About the HIP Methodology ▸
Generic ratings are intentionally conservative. They represent only what the HIP methodology can confirm from
publicly available specification data, before any manufacturer-supplied evidence is reviewed. Most categories sit
in the 2–4 range at the pre-verification baseline. This is the methodology working as designed: it makes the gap
between current market practice and demonstrable resilience legible to consumers, manufacturers, and procurement
buyers. Verified assessment is the path across that gap, and the HIP Mark is the proof of crossing it.

Consumer Summary
This hair straightener has a HIP Score of 2.7 out of 10, indicating it performs poorly in terms of sustainability and circularity. Its Regenerative Index is -7.0, which means the product is depleting resources rather than supporting a regenerative cycle. Overall, it is a conventional item with no recycled materials and no plan for repair or recycling at the end of its life.
What This Means For You
When shopping for hair straighteners, look for products that disclose the use of recycled materials and offer a clear path for recycling or repair. Prioritize brands that provide spare parts, repair manuals, and take-back schemes to extend the product's life. Avoid items that are glued shut, lack warranty support, or are made entirely from virgin materials without any end-of-life plan.
