Short answer
This page is the index for everything we publish on Hair and scalp care: scalp-first routines, oil evidence, and honest limits. It lists every guide, tool and reference table in the order we would use them, and each one is written to answer a question rather than to fill a page.

Start with the guides
- How to use a scalp massager: wet or dry, and how often — Wet use cleans, dry use spreads oil, and both are fine. What matters is pressure, tangles and how often you do it. Here is the practical version, plus an honest read of the evidence
- Rosemary oil for hair: what the evidence actually shows — A single randomised trial compared rosemary oil with 2% minoxidil and found no significant difference. It had no placebo arm and used a weaker minoxidil strength. Here is the honest read, and how to use rosemary sensibly anyway
- A scalp-first wash-day routine, in order — Wash day has a correct order, and it is not the order most people use. Scalp first, lengths second, oil before water, heat last. Here is the sequence with the reasoning and the sources

How this index is orderedGuides first, because they explain the trade-off. Tools second, because a number that applies to you beats a general recommendation. Reference tables last, for the details you check once. Nothing here is ordered by commission.
