Weekly considered essays
Clinical breakdown of active molecules — what penetrates the cuticle, what coats, what actually nourishes.
Evidence-based analysis of sebum regulation, pH balance, and the microbial ecology beneath the lipid barrier.
How natural oils interact with your body's chemistry — not marketing claims, but measured biological response.
Quarterly protocols aligned with humidity, temperature, and hormonal shifts that affect follicle behaviour.
Unsponsored ingredient-list deconstructions. We read the INCI so you know exactly what touches your scalp.
Simple, repeatable habits based on trichological principles — designed for real mornings, not laboratory conditions.
Finally, someone who explains ingredients without selling me anything. I completely changed my wash routine after the ceramide essay and my stylist noticed the difference within a month.
The scalp microbiome series was a revelation. I'd been over-washing for years. Three weeks after adjusting, the itchiness I'd accepted as normal just… stopped.
I look forward to this email more than any podcast or blog in my feed. It's calm, it's scientific, and it never tries to upsell me. Rare on the internet.
As a dermatology nurse, I'm picky about sourcing. Maya's citations are solid, and her approach to follicle adaptation is exactly what patients need to hear.
