The biology behind why a scar looks the way it does, and what changes that picture.
Swipe through the stages of how scars form, why your eye keeps going to them, and what realistic improvement actually looks like🖤
Most people carry a scar they've quietly assumed is permanent. A C-section line. A surgery scar that healed thicker than expected. Stretch marks from pregnancy or a growth spurt. An old injury from sport or an accident.
What they all share is the same underlying biology, collagen that laid down in a disorganised way during healing. That disorganisation is what your eye keeps catching when it lands on the scar.
Collagen, even in scar tissue, is remodellable🖤

Hair follicles don't disappear overnight. They move through a slow, predictable cycle of shrinking long before the change is visible.
One small thing that's worth doing if you've started noticing change: book a scalp assessment while there's still something to assess. The earlier the window, the more options sit on the table🖤

The three phases of a hair follicle's lifespan, and why waiting is rarely the answer.
Active. Miniaturising. Gone.
Swipe for what each phase looks like, and where the window for action actually sits🖤
Most men think hair loss starts the moment they notice it. It doesn't.
By the time the change is visible in the mirror, the follicles affected have already moved through several growth cycles of gradual shrinking. The visible thinning is the late stage, not the beginning.
The earlier window is the one that matters. While follicles are still cycling, there's something to work with🖤

Ni****ne constricts the blood vessels that feed your skin and scalp by up to 30%. That effect doesn't change based on whether the ni****ne arrives as smoke or as v***r.
One small thing that supports the body if you're using either: build in a few hours of ni****ne-free time before bed, when overnight repair is at its peak🖤

The clinical layer most people don't get told about ni****ne.
Carbon monoxide. Vasoconstriction. Free radicals. Collagen breakdown. These are the named mechanisms that show up in skin and hair over time.
Swipe for what's actually happening, and where va**ng sits in the picture🖤

Va**ng was sold as the safer option, and on a few measures it is. On the measures that affect skin and hair, the picture is less convincing.
Ni****ne is the active component. It constricts the vessels that feed skin and scalp, regardless of whether you're inhaling smoke or vapour.
This isn't about giving things up. It's about knowing what your body is responding to🖤

Hair grows in three phases, and the rhythm between them is what changes through perimenopause.
Anagen is the active growth phase, where 85 to 90 percent of your hair lives, for two to six years at a time.
Catagen is the short transition phase, around two to three weeks, where growth slows and the follicle prepares to rest.
Telogen is the resting and shedding phase. It's normally a small fraction of your hair, but it increases through perimenopause, which is why the shedding can feel sudden even though the shift has been gradual.
One small thing that supports the body through this shift: ask your GP to check your ferritin at your next blood test. Above 70 is what hair tends to need to stay in its growing phase. Most people don't think to ask, and most labs flag "normal" at a much lower number.
The follicles haven't given up. The conditions around them have changed🖤

The clinical layer behind the shedding most women experience in their 40's.
Hair grows in three phases: anagen, catagen and telogen. Perimenopause shortens the first and tips more hairs into the last. The result is sudden-looking shedding from a gradual hormonal shift.
