6.4 HIP
This is the best score a product in this category can reach when the maker shares full data about
its materials, supply chain, repairs, and end-of-life. It is a target, not a product on sale today.

Score Breakdown
How rare are the materials?
MSI · 20%
5.5
Why this score ▸
It uses a special metal needed for the motor, so it cannot be made entirely from recycled parts. This keeps the score in the middle range even though it uses a lot of recycled material.
Technical detail ▸
The product contains neodymium at 3% by weight, which is a functionally critical EU Critical Raw Material, preventing eligibility for the 7-8 band. While the 77% recycled content and diverse supply chain (Germany, Chile, Australia) provide significant credit, the presence of this functional CRM limits the score to the moderate range.
Where do the materials come from?
SCR · 18%
5.5
Why this score ▸
The parts come from safe places like Germany and Australia where rules are followed. This helps make sure the materials are gathered without causing harm.
Technical detail ▸
The supply chain sources primary materials from Germany, Chile, and Australia, which are politically stable jurisdictions with acceptable governance scores. The product adheres to the OECD Due Diligence Guidance and has a documented alternative supplier, mitigating concentration risks for copper and nichrome components typical of hair dryers.
Can it be recycled?
RC · 18%
8.0
Why this score ▸
You can easily take it apart to recycle most of the metal inside. The company also has a plan to collect old units so they do not end up in trash.
Technical detail ▸
The product features screw-based disassembly, a compliant recycling label, and an active manufacturer take-back scheme, enabling 92% of materials to enter verified recycling streams. This performance aligns with the Well-Designed for Recovery category, where over 60% of weight is practically recovered through established infrastructure in Germany.
Can you fix it?
R · 13%
8.0
Why this score ▸
All the screws are standard types, so you can fix it yourself with common tools. Spare parts are available for ten years to keep it working longer.
Technical detail ▸
The product features all standard screws and has spare parts available for 10 years, supported by a public service manual. The iFixit score of 8 confirms the design allows for practical independent repair, aligning with the criteria for products designed for repair.
Is it made fairly?
SEI · 8%
8.0
Why this score ▸
The factory follows strict rules to protect the environment and treat workers fairly. It is located in a place with strong laws to ensure safe working conditions.
Technical detail ▸
The manufacturer holds ISO 14001:2015 and ASI certifications, and an RBA audit has been completed. Production occurs in Germany, an OECD jurisdiction with strong labour law enforcement, supported by a modern slavery statement and ILO compliance claims.
How long will it last?
PL · 8%
8.0
Why this score ▸
It comes with a five-year guarantee and is built to last for ten years. You can replace broken pieces to keep using it for a long time.
Technical detail ▸
The product achieves a high score due to a 5-year warranty and a stated design life of 10 years, which aligns with the criteria for above-average lifespan. The modular design further supports longevity by enabling component replacement. Although the IP rating and software support were not submitted, the strong warranty and design specifications drive the rating into the 7-8 band.
Does it give back to nature?
RI · 15% · scale −10 to +10
-3.0
Why this score ▸
It uses a lot of recycled metal and returns old parts to be reused. However, it does not yet use materials that help nature grow back.
Technical detail ▸
The product qualifies for the Extractive band minimum of -3 because it contains 77% recycled content and operates a verified closed-loop take-back scheme, explicitly excluding the Depleting floor. While the closed-loop programme returns aluminium to an ASI-certified smelter, the absence of Regenerative Organic Certified (ROC) inputs or verified ecosystem restoration prevents a score above the Extractive range.
MSI 20% · SCR 18% · RC 18% · R 13% · SEI 8% · PL 8% · RI 15% = 100%
About the HIP Methodology ▸
Starting scores are low on purpose. We only count what we can confirm from public data,
so most products sit between 2 and 4 out of 10 before a maker shares their own evidence.
That gap between the starting score and what a product could reach is the whole point.
When a maker proves what their product is really made of, the score goes up.
The HIP Mark shows it has been checked.

Consumer Summary
This hair dryer earns an overall score of 6.4 out of 10, which matches the current market baseline for small appliances. It has a Regenerative Index of -3, meaning it uses many recycled parts but does not yet give back to nature. The product is built to last and can be easily fixed, though it relies on new materials for some key parts.
What This Means For You
When buying a hair dryer, look for models that last a long time and have parts you can replace yourself. Choose items made with recycled materials to help reduce waste. Avoid products that are glued together or cannot be repaired when they break.
