Our Product Rating System

Our Product Rating System

First, Camille (co-creator of Welpr) hand picks cleaner product options from a variety of sources.

Next, we collect information about each product's safety, consumer satisfaction, and eco-ethical standing.

Finally, we run all this information through an algorithm that calculates the Welpr Rating.

Welpr Rating:

5.0/5

The Welpr Rating takes into account 3 things:

  1. Product Safety
  2. Consumer Satisfaction
  3. Ethics & Environment
Product safety

Part 1: Product safety

We evaluate safety information from 3rd party organizations (e.g. EWG, Made Safe, etc.). Instead of relying solely on any one of these companies for safety information, we assess all of them.

Consumer satisfaction

Part 2: Consumer satisfaction

We scour the web for consumer ratings and reviews to verify products are not only cleaner options, but also effective. Products can either be Above Average, Average, or Below average for their respective category (e.g. cleaning products).

Ethics & Environment

Part 3: Ethics & Environment

When you buy a product, you’re supporting that company with your dollars. We believe it’s important to support ethical companies, so we pool together certifications that verify a company's ethics and environmental impact.

Common Harmful Chemicals in Hair Root Powder & Touch Up

Chemical Name

Why it’s harmful

Talc

Talc, a naturally occurring mineral, is commonly used in cosmetics and personal care products for its moisture-absorbing, smoothing, and anti-caking properties. It is also utilized in food products and animal feed. However, some talc may be contaminated with asbestos fibers, which are linked to cancer. This contamination occurs due to the proximity of talc deposits to asbestos mining sites. Health concerns associated with talc include irritation, cancer risks, and potential organ system toxicity.

Octamethyltrisiloxane

Octamethylcyclotetrasiloxane is a versatile chemical used in extreme temperature silicone oils, foam suppression in lubricating oils, and in various industries like electronics, construction, cosmetics, and more. It is flammable and very toxic to aquatic life, potentially causing long-lasting harm. Additionally, it is classified as toxic for reproduction category 3, but it is not currently regulated in cosmetics and has not been evaluated by the Scientific Committee on Cosmetology.

Silicon Dioxide

Silica, also known as silicon dioxide with the formula SiO2, occurs in many forms that have the same chemical composition but differ in atomic arrangements. These forms are categorized into two groups: crystalline silica (c-silica) and amorphous silica (a-silica). The difference lies in their structure; c-silica has repeating patterns of silicon and oxygen, while a-silica structures are more random. All silica forms are odorless solids that form non-explosive dust when suspended in the air. Additionally, silica can react with other metallic elements and oxides to form silicates.

Titanium Dioxide

The study on 1,576 U.S. workers exposed to TiO2 for over a year from 1956 to 1985 showed no increase in lung cancer or chronic respiratory disease, and no cases of pulmonary fibrosis. Cases of pulmonary fibrosis related to TiO2 exposure have been reported, possibly due to silica contamination. There are no listed effects for short-term or long-term exposure. Although NIOSH recognises ultrafine TiO2 as a potential occupational carcinogen, data is insufficient to classify fine TiO2 similarly. Epidemiological studies do not provide clear evidence of lung cancer risks from TiO2 dust exposure.

Hey, I’m Camille—co-creator of Welpr and your go-to guide for all things clean living. After selling my last company in the health food space, I went non-toxic to heal an autoimmune condition. It did wonders for my health, but navigating which products to buy wasn’t easy. We built Welpr to make that journey feel a bit easier.  When I’m not working on Welpr, you’ll usually find me in the sauna, sipping a raw milk latte while doing a puzzle, or walking with my pit bull Romeo in my hometown of Austin, TX.
