I’m an enthusiastic individual with a passion for digital design. I’m interested in the promotion of sustainability and how this can be innovatively incorporated into solutions for future design problems.

Final Project


Re-rinse is a shampoo bar grater and container for sustainable and efficient hair washing. The current dominance of liquid shampoo in the haircare market is contributing to global cosmetic packaging waste. The UK throws away 520 million shampoo bottles every year.

How does it work?

Remove the handle part from the product’s main body and attach the ‘Re-Rinse’ branded shampoo bar to the spikes on the handle’s base. Rotate the handle part downwards, pushing the shampoo bar against the grater surface producing shampoo bar flakes. Remove the lid, where the shampoo flakes are collected and lather to wash hair.


An internal thread guides the handle part and shampoo bar towards the grater at a consistent rate meaning the bar’s surface is grated evenly. Features a debossed ‘Re-Rinse’ water droplet logo on the handle part acting as aesthetic detail and an indicator for the amount of rotation done, therefore indicating the amount of flakes being grated.

Shampoo bar refills

Every time you refill your Re-Rinse container, you’ll save 40g plastic going to landfill. Re-Rinse branded shampoo bars fit perfectly into the product container, aligning with the centre point of the handle’s base whilst attaching to the spikes.

Straight through the letterbox

Re-Rinse provides a convenient online service delivering branded shampoo bars of varied scents to your door, right through the letter box. Discount on refills are available through applying for the subscription service.

‘How can we reduce the strain on the NHS?’

This strain can be reduced by minimising hospital visits. ‘Medi’ focuses on preventable causes for hospital visits such as harm due to medication errors for children. Harm due to medication errors costs the NHS an extra £100m and 180,000 hospital bed days per year.

How does it work?

Pour child’s antibiotics into the domed tube and clip all 3 ‘valve’ sections together- these create quantity control. Flip the product upside down. Twist the top section then middle section aligning the single mark and double marks. Give child antibiotics and keep track of daily dose frequencies with switches 1-3.

Medication Made Easy

‘Medi’ helps parents/guardians reduce medication errors for sick children at home by providing accurate dosage sizes and frequencies of antibiotics. Nearly 1 in 5 children may receive an inappropriate dose of antibiotic. ‘Medi’ is a more accurate alternative to existing solutions: medicine spoon and syringe.

Work Experience

For my year in industry 2021-22 I was the ‘Product Marketing & Design intern’ at ID&C Wristbands in Royal Tunbridge Wells. I worked closely with the product development team, brainstorming new product ideas. I ran the company’s social media accounts creating content and scheduling regular posts. Attending on site events such as COP26 and the Platinum Jubilee, talking to clients face to face, was one of my highlights. I designed accreditation (wristbands, passes and lanyards) for real events whilst developing my skills with Adobe creative suite programmes.
