Did you mean Hair Cycle Regulation?

Glossary Hair Cycle Regulation

biological processes controlling hair growth, rest, and shedding phases

Hair Cycle Regulation refers to the biological processes that control the growth, rest, and shedding phases of hair follicles. This cycle includes three main stages: anagen (growth), catagen (transitional), and telogen (resting). Proper regulation ensures healthy hair growth and prevents conditions like alopecia, where hair loss occurs due to disruptions in this cycle.

research Novel insights into the pathways regulating the canine hair cycle and their deregulation in alopecia X

18 citations , October 2017 in “PLOS ONE”

This study found that in Pomeranians with Alopecia X, key genes in the Wnt and Shh signaling pathways and stem cell markers are downregulated, which may explain the absence of anagen hair follicles.

community My hair after 3 steroid cycles

in Progress Pictures 27 upvotes 2 years ago

A user shared their hair progress after three steroid cycles, using 5% minoxidil and 100mg RU58841 daily. They are considering a hair transplant due to paranoia about shedding.

community Positive Hair Result in Patient using Tirzepatide

4 upvotes 1 year ago

A 57-year-old man with male pattern hair loss and insulin resistance experienced hair regrowth and weight loss after using tirzepatide, without other hair treatments. Dysregulated glucose metabolism is linked to hair loss, with tirzepatide potentially improving hair density by normalizing insulin resistance.

community Hair loss research focused on chemistry for decades because we misunderstood the mechanics of growth.

51 upvotes 7 months ago

Hair growth relies on mechanical forces, not just chemicals, with tissue acting like a motor. Minoxidil and finasteride help, but maintaining tissue elasticity and addressing mechanical issues are essential.

community Female diffuse hair loss on spiro with irregular periods (photos) + genetic hair loss

in Female 16 upvotes 1 year ago

A 34-year-old woman is experiencing diffuse hair loss and irregular periods, possibly due to long-term spironolactone use. She is considering minoxidil and finasteride for treatment and seeking medical advice for androgenic alopecia and hormonal imbalances.

community 10 months on fin and hairline destroyed.

in Finasteride/Dutasteride 46 upvotes 2 years ago

A user experienced severe hair shedding and hairline recession after 10 months on finasteride. They are considering switching to dutasteride or adding minoxidil.

learn Hair Transplant

What happens after a hair transplant? Expect mild swelling and redness, with new hair growth starting in 3 to 6 months.
When will I see new hair growth after a hair transplant? New hair growth usually starts 2-4 months after a hair transplant.

learn Cyproterone

How long does it take for cyproterone to work on hair loss? There is no reliable published figure for how fast cyproterone works on hair loss: the hair cycle means nothing shows for months, the one randomised trial assessed women at twelve months, and community reports range from about six months to two years — with some people seeing no change at all.

learn horsetail extract

How long should you use horsetail extract before noticing stronger or thicker hair? No published trial has tested horsetail extract for hair thinning, so no evidence-based timeline exists; the hair cycle means any supplement needs at least three months, and more realistically five to six, before a change could be visible at all.

learn Rapamycin

Is rapamycin safe for long-term use on the scalp, or should it be used in cycles? There is no published human trial of topical rapamycin on the scalp, so nobody knows whether long-term use is safe; the idea of cycling it comes from community practice and theory, not from any study or guideline, and rapamycin for hair loss is an off-label use of a prescription immunosuppressant.
