Frequently asked questions
Seeking answers? We've got you covered!
How tweakit works?
Tweakit pioneers high performance, sustainable and refillable personal care. Our mission is to change the way we wash our hair and bodies for the better and with minimal environmental impact. No single use plastic, no monthly plastic recycling, no deliveries of heavy, water-laden beauty products.
Our power powders are waterless, blending concentrated, 99% naturally derived ingredients that, once activated with water by you, create luxurious shampoo, conditioner and body wash formulas.
Each concentrated powder tube is small and lightweight, making it effortlessly storable and transportable. The Tweakit Forever Bottle, designed to be used to create your product, has been specially formulated as a bottle for life - lightweight, ultra-durable, BPA-free, dishwasher safe and, should you ever decide to stop using Tweakit, 100% recyclable.
How do i make tweakit products?
Creating your Tweakit shampoo, conditioner and body wash are as easy as 1, 2, 3.
- Take your Tweakit Forever Bottle plus your choice of shampoo, conditioner, or body wash.
- Fill the Forever Bottle with 250ml of warm tap water (up to guide line). While cold tap water will be fine, keeping it warm helps the powder dissolve faster.
- Empty contents of one tube into a bottle, replace lid, shake well and leave to stand for at least 30 minutes.
What shouldn’t i do when making my tweakit products?
We’ve designed Tweakit to be as easy to use as possible. There are a just a few steps we recommend you take to keep your products in peak performance:
- Be sure to add only the correct amount of water in each bottle (250ml). Use the line provided on the bottle as a guide.
- Use warm tap water to aid powder diffusion.
- Keep your shampoo, conditioner and body wash out of direct sunlight.
Between each refill, wash your Forever Bottle thoroughly in hot, soapy water or pop it in your next dishwasher cycle.
Should i use cold water?
While you can use cool tap water, warm/hot water will ensure the concentrated powder dissolves quicker.
How long does the liquid stay effective after mixing? / What is the shelf life of the shampoo, conditioner or body wash?
Once the Tweakit formula has been activated by water, we recommend you use it within 12 months. Your product may work effectively long after this date, but 12 months is the recommendation based on the safety and compliance tests undertaken.
