Glossary Transection

accidental cutting of hair follicles during transplant procedures

Transection refers to the accidental cutting or damaging of hair follicles during a hair transplant procedure. This can occur when the surgical instruments used to extract or implant hair grafts inadvertently sever the follicles, potentially reducing the success rate of the transplant and affecting hair growth outcomes. For professionals, minimizing transection is crucial for maximizing graft survival and achieving optimal results.

community Transitioning from topical Fin to oral Fin: anything I should know?

5 upvotes 1 month ago

The conversation is about transitioning from topical to oral finasteride for hair loss treatment. Users suggest tapering off the topical while starting the oral dose, with some recommending using both simultaneously for a period.

community Transitioning off daily Oral Dutasteride (0.5mg) for long-term (multi-decade) maintenance. Which protocol is best?

in Finasteride/Dutasteride 6 upvotes 1 month ago

The conversation discusses transitioning from daily oral Dutasteride to a long-term maintenance protocol for hair loss, considering options like oral Finasteride with topical Dutasteride, pulsed oral Dutasteride, and oral Finasteride with topical Finasteride. The consensus suggests maintaining a baseline with daily Finasteride and using Dutasteride twice a week to minimize shedding while reducing systemic exposure.

community Transition protocols from fin to dut

in Chat 2 upvotes 6 months ago

Transitioning from finasteride to dutasteride for hair loss, with suggestions to either slowly transition or frontload dutasteride. The user is also using minoxidil, nizoral, needling, and LLLT.

community Transitioned from topical minoxidil to oral min and the shedding is crazy!

in Minoxidil 243 upvotes 8 months ago

Switching from topical to oral minoxidil can cause initial hair shedding but may lead to thicker hair growth. Many users combine it with finasteride, experiencing varying side effects.

learn Cyproterone

Is cyproterone safe to use during gender transition? Regulators and a large French cohort study link higher-dose, long-term cyproterone acetate to meningioma, and its label also lists liver-enzyme and mood effects — so it is not a drug anyone should call safe in the abstract, and its use in gender-affirming care is a prescriber's decision with monitoring.

learn Setipiprant

Can Setipiprant be used safely by women or people undergoing gender transition? Setipiprant's safety for women and those in transition is not well-studied.

learn HMI-115

Who can benefit the most from HMI-115: men, women, or people in transition? There is no published trial showing that any one group benefits most from HMI-115: the only released human efficacy data is a company press release on a 16-person Phase 1b, and it reported hair-count results for the 12 men only.
