The use of peptides (such as GHK-Cu) for hair health is based on studies suggesting stimulation of hair follicle cell proliferation, although clinical evidence is often limited to in vitro studies or small sample sizes. Application to a dry scalp is a logical practice to avoid dilution of the product by residual moisture, thereby facilitating skin penetration. Low-level laser therapy (LLLT) is supported by several meta-analyses and randomized controlled trials (RCTs) indicating modest but real efficacy in improving hair density in individuals with androgenetic alopecia. However, the idea that red light 'specifically optimizes the absorption' of peptides lacks direct evidence; it acts instead through a distinct biological mechanism (mitochondrial photobiomodulation). Combining the two is a coherent multimodal approach, although the exact synergistic effect remains to be confirmed by more robust studies. The protocol is safe, but individual results vary considerably depending on genetics.

Skin really does change across the cycle: drier and more barrier-fragile right before your period, oilier around ovulation — a documented hormonal rhythm, not just a feeling.

Vitamin C is a well-documented, essential cofactor for collagen synthesis (it activates the enzymes that stabilize its structure); gelatin supplies the basic amino acids (glycine, proline, hydroxyproline). The biochemistry behind this recipe holds up — what isn't directly measured is the visible effect on 'skin glow.'

The ice-water face plunge at wake-up (from Ashton Hall's viral routine) gives a real short-term alertness bump — the rest of the ritual, especially rubbing a banana peel on the face, is more theater than skincare.

Other advice in the Register that leans on the same research.

Regular sauna use (especially dry sauna) is associated with better cardiovascular longevity — but the claim that jumping into cold water right after "undoes" that benefit, or that icing your testicles protects fertility, are untested extrapolations layered on top of a real association.

Dry Finnish sauna is the best-studied form for long-term cardiovascular benefit, at several sessions a week; but the claim that sweating clears microplastics from the body has no source — it's a leap from a study about heavy metals, not microplastics.

There's a real mechanism behind part of this idea — heat trapped by tight underwear affects male fertility — but stretching it into a universal "anti-aging" habit (circulation, inflammation, skin barrier, hormones, deep sleep, for everyone) goes well beyond what the research shows.
