BEFORE YOU SHORTLIST
Shampoos
Start with the product’s stated purpose, then compare the practical details.
- Purpose
- Read the pack rather than inferring a benefit from “growth” or “thickening” in a name.
- Size and price
- Compare the same unit. Add shipping, minimum-order requirements and refill terms.
- Directions
- Use the instructions for that exact product. This guide does not set a washing frequency.
- Your shortlist
- Keep a question list if the formula or intended use is unclear.

Conditioners & leave-ins
The format is part of the decision. A rinse-out product and a leave-in are not interchangeable instructions.
- Format
- Identify whether the label says rinse out or leave in.
- Application
- Check the product’s directions for where and how to apply it.
- Comparison
- Record pack size, unit cost and seller return terms.
- Experience claims
- A published tester’s experience may be useful context, but does not guarantee your result.

Serums & scalp care
“Serum” is a format word. Check the exact product before comparing its claims.
- Product category
- Read whether it is presented as a cosmetic, medicine or another category.
- Intended use
- Separate cosmetic appearance claims from claims about treating hair loss.
- Label details
- For a medicine, check the Drug Facts panel, including warnings and directions.
- Unanswered questions
- Ask a pharmacist or clinician about treatment instructions or uncertain suitability.
Use the label checklist →Small questions. Useful answers.
Do I need to replace my whole routine?
A buying guide is not a requirement to purchase. Begin by listing what you already own and the question you want a new product to answer.
Is a higher price proof of better results?
The price tag does not provide clinical evidence. Compare the exact product, its purpose and the source behind the claim. Our evidence guide helps you organize that reading.
Check a claim →Where are the product test scores?
We do not publish scores for testing we have not performed. Our current directory compares published information and explains its limits.
