✓Well SupportedCombining botox with finasteride can lead to a 35% increase in hair count over a year.✓Well SupportedPractices like dry needling, scalp massage, or other methods to improve blood flow to the scalp can be beneficial for hair growth.◐Partially SupportedScalp massage and tiny needling devices may help with hair growth by relaxing scalp muscles or creating inflammation at the dermal papillae level.◐Partially SupportedMicroneedling, even without minoxidil, has been shown to increase hair counts in control groups of studies.◐Partially SupportedPattern hair loss is primarily caused by DHT, which induces transforming growth factor beta-1 and leads to apoptosis in dermal papilla cells.

Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

◐Partially SupportedParafollicular fibrosis accumulates with hair loss and is not targeted by finasteride.

◐Partially SupportedApproximately 80% of individuals with androgenetic alopecia exhibit very tight scalps, suggesting chronic contraction of the surrounding muscles.

◐Partially SupportedThe DHT-driven explanation for pattern hair loss is true but incomplete.

◐Partially SupportedScalp perimeter botox injections showed 75-79% response rates and 18-21% hair regrowth in replication studies.

◐Partially SupportedMicroneedling can improve scar tissue outcomes in the scalp and skin by eliciting an acute inflammatory response that signals to reduce scar tissue and initiate anagen signaling for improved hair counts.

◐Partially SupportedPersistent and high tension in scalp tissues can induce androgen cofactors and influence adjacent cells like dermal papilla cells.

◐Partially Supported75% of individuals adhering to scalp massage techniques for 8+ months reported either complete stabilization or some regrowth of pattern hair loss.

◐Partially SupportedAndrogen receptor co-activators like Hic5 and Ara55 may intensify DHT's effects on scalp cells, leading to miniaturization, and might be absent in beard and chest hairs.

◐Partially SupportedDHT is paradoxically associated with better facial and chest hair regrowth while causing scalp hair loss.

◐Partially SupportedMassaging the scalp perimeter may elicit similar mechanisms to botulinum toxin therapies by releasing muscles from chronic contraction.

◐Partially SupportedScalp muscle contractions may reduce DHT levels by reducing blood flow to the scalp, thereby favoring testosterone conversion to estradiol over DHT.

◐Partially SupportedDubois trans contracture shares similarities with processes seen in balding scalps.

◐Partially SupportedFinasteride reduces DHT systemically, and other factors beyond genetics may explain increased hair loss on the scalp versus other body parts.

◐Partially SupportedTension-mediated environments, such as in a tight scalp, can induce DHT, transforming growth factor beta-1, and fibrosis in the prostate.

◐Partially SupportedMicroneedling can improve scar tissue outcomes on the scalp and skin by eliciting an inflammatory response that reduces scar tissue and improves hair counts.

◐Partially SupportedChronic scalp tension can lead to fibrosis, increased androgen activity, and transforming growth factor beta 1, similar to mechanisms in other tissues.

◐Partially SupportedScalp muscle contractions can reduce blood flow to the scalp, potentially leading to lower transcutaneous oxygen levels in balding regions.

◐Partially SupportedReducing scalp tension may decrease inflammation-mediated DHT cascades and improve blood flow to the scalp.
