Which habit was doing the most damage in hindsight - heat, the towel, or brushing it wet?

Going to disagree with both of the above and say it's the towel plus whatever you tie it up with.

Rough drying with a terry towel is thousands of tiny hooks catching on a raised cuticle, and the classic towel turban puts the whole weight of wet hair on the hairline. Add a tight elastic in the same spot every day and you have a mechanical explanation for a band of breakage at one height, which is what she's describing - heat damage is usually more diffuse and worst at the ends.

Microfibre or an old cotton t-shirt, squeeze rather than rub, and change where the tie sits. Cost me nothing.

Cold brew with the beans I use for filter comes out flat and papery - water temp or grind?

Different tack. If what you love about that Ethiopian is the floral acidity, cold brew is the wrong process for it, full stop, and no amount of tinkering will get it back. Brew it hot straight onto ice instead. Same V60, same dose, but replace about 40 percent of the brew water with the equivalent weight of ice in the carafe and brew the rest hot at your normal recipe. You get the aromatics because you extracted hot, and it chills instantly so they do not cook off. That is the drink you actually want.

Eight months of practising at home and I've never taken a class: what am I missing that I can't see?

Slightly against the grain: I don't think the danger is the poses you're doing badly, it's the poses you're not doing at all.

Home practice tends to become a groove: the same twenty poses that feel good, in the same order, for years. Nobody's asking you to do the awkward thing, so you don't. That's what a class actually gives you: someone else picking, including things you'd never choose.

Alignment errors that hurt tend to announce themselves. A gap in your practice never does.

Is a scalp exfoliant doing anything my shampoo isn't, or is it shampoo with grit in it?

Going to push back on the whole purchase, kindly. Itchy plus flaky plus oily roots is a very common trio and in my case it wasn't a buildup problem at all, a pharmacist looked at it and it was seborrhoeic dermatitis, which is driven by yeast that lives on everyone's skin and thrives in sebum.

Exfoliating that felt good for two days and then it came back angrier, because I was scrubbing inflamed skin. What actually worked was an antifungal shampoo left on for the time it says on the bottle, which is longer than anyone does naturally. I'm not diagnosing you from a paragraph, I'd just say a GP or pharmacist visit is cheaper than the scrub and will tell you which problem you actually have before you spend anything.

Four minutes in the press tastes thin and eight tastes harsh - where did you land?

I run a press and a Clever side by side depending on mood and this is my press routine: preheat the glass with hot water and dump it, 70 g to a litre same as you, pour, wait four minutes, break the crust with a spoon, then skim the foam and floating grounds off the top with two spoons and bin them. Wait another five minutes with the lid off. Then press the plunger down just to the surface, not through the bed, and pour.

Nine minutes total sounds mad until you try it. The skim removes the fines that cause most of the harshness and the extra rest gets you body without the drying finish.

Drip machine takes 11 minutes for a full carafe and the coffee comes out thin

Add a thermometer to the argument. Brewing temperature wants to be in the low to mid nineties Celsius and a scaled or simply cheap machine often sits ten degrees under that. I stuck a probe in the brew basket on a machine that was making exactly the thin cup you are describing and it peaked at 84 C, which is why it tasted like weak tea no matter what the dose was.

Your 60 g per litre is the standard ratio and is not the problem. If it still brews cold after descaling, the machine is the problem, and no grind adjustment will save it.

Where do you get haircare information that cites studies instead of selling you something?

Practical test I use before believing anything: does the source ever say a product category is unnecessary?

A blog that has never once concluded "you don't need this" is a catalogue. The ones worth reading have posts saying that most people don't need protein treatments, that porosity tests in a glass of water don't work, that a £40 serum and a £6 one contain the same three actives. Those posts cost the author money, which is why they're the signal.
