This study found that microneedling with longer needles (3 mm) showed better hair regrowth in dogs with hair cycle arrest, although most experienced recurrent hair loss during follow-up. Some dogs also developed minor, temporary itching.

research Oestrogen receptor antagonist and hair regrowth in dogs with hair cycle arrest (alopecia X)

11 citations , January 2007 in “Veterinary dermatology”

community Regrowth After Minoxidil: How to Restore Natural Hair Cycle?

in General 108 upvotes 9 months ago

Minoxidil use led to a disrupted hair cycle and hair damage. The user seeks ways to restore normal hair growth.

community if hair follicle miniaturization happens slowly and gradually over a few hair cycles then wouldn't that mean that to regain maximum or top thickness from treatment you would at least need 5-10 years?

in Research/Science 53 upvotes 10 months ago

Hair regrowth from treatments like finasteride, dutasteride, and minoxidil can take several years, with most visible results appearing within 1-2 years and potential improvements continuing up to 10 years. Consistency and patience are crucial for achieving maximum hair thickness, as hair miniaturization and regrowth are gradual processes.

community The never ending cycle as a fin+min user

1356 upvotes 4 weeks ago

Hair loss treatments like finasteride and minoxidil can cause cycles of shedding and regrowth, leading to fluctuating emotions. Users experience periods of hair improvement followed by shedding, with some finding long-term stabilization elusive.

community Help me understand hair/shed cycles. After 6 months of Fin, losing ground again

15 upvotes 4 years ago

After 6 months of using finasteride, minoxidil, RU58841, and microneedling, the user experienced hair regrowth but then noticed a significant shed, returning to the initial state of hair loss. Another user responded that shedding every 6-8 months is normal when using finasteride and advised to continue the treatment for thicker hair regrowth.

community Very agressive protection / regrowth stack on steroids

in Journals / Progress Pictures 223 upvotes 8 months ago

A 24-year-old with hair thinning is using a regimen including dutasteride, RU58841, HGH, GHK-cu, and other compounds to protect and regrow hair. They are also incorporating a mild cutting cycle with testosterone propionate, anavar, and tirzepatide.

learn Hair Transplant

When will I see new hair growth after a hair transplant? New hair growth usually starts 2-4 months after a hair transplant.

learn Low Level Laser Therapy

Red-light devices, such as caps, combs and helmets, used on the scalp

learn Bimatoprost

Prostaglandin eye drop used for glaucoma and eyelash growth

How does bimatoprost compare to minoxidil for hair regrowth? Minoxidil is FDA-approved for scalp hair loss and backed by decades of large trials; bimatoprost is approved only for eyelashes, and the published scalp evidence is limited to small short studies, so on the scalp it is off-label and experimental.

learn Sulforaphane

Compound found in broccoli sprouts

learn Latanoprost

Prostaglandin eye drop used for glaucoma

Is latanoprost more effective for hair regrowth than minoxidil? No trial has compared latanoprost and minoxidil head to head. Minoxidil has large randomized trials and FDA approval for hair loss, while latanoprost's scalp evidence is a single 24-week pilot in 16 men, so the published evidence does not support latanoprost being the more effective option.

learn Minoxidil

Vasodilator used on the scalp and, at low doses, as a tablet

learn SCUBE3

What do clinical trials say about the safety and effectiveness of SCUBE3 for hair regrowth? No clinical trial of SCUBE3 for hair regrowth has been registered on ClinicalTrials.gov or published, so there is no human safety or effectiveness data. The evidence is limited to one 2022 laboratory and mouse study reporting that SCUBE3 activates hair follicle stem cells through TGF-beta signalling.

learn Spironolactone

Is spironolactone better for hair regrowth as a pill or as a scalp solution? Oral spironolactone has the stronger published evidence for hair regrowth; topical versions cause fewer systemic side effects but have been studied far less, and no trial has compared the two head to head.
