research Stimulation of root hair elongation in Arabidopsis thaliana by low phosphorus availability

578 citations , May 1996 in “Plant Cell & Environment”

This study found that Arabidopsis thaliana plants developed longer root hairs under low phosphorus conditions, suggesting auxin involvement in this adaptive response.

research Stimulation of ectodermal organ development by Ectodysplasin-A1

249 citations , May 2003 in “Developmental Biology”

Ectodysplasin-A1 is crucial for developing hair, teeth, and glands.

research A fast liquid chromatographic/mass spectrometric screening method for the simultaneous detection of synthetic glucocorticoids, some stimulants, anti‐oestrogen drugs and synthetic anabolic steroids

100 citations , October 2006 in “Rapid Communications in Mass Spectrometry”

This study describes a fast LC/MS/MS method for detecting various synthetic drugs in urine, meeting World Anti-Doping Agency performance limits.

research Stimulation of Hair Growth by Small Molecules that Activate Autophagy

88 citations , June 2019 in “Cell reports”

This study found that activating autophagy with specific small molecules and drugs can stimulate hair growth by initiating the anagen phase in dormant hair follicles, suggesting a potential treatment for hair loss.

research Stimulation of Hair Growth by Topical Application of FK506, a Potent Immunosuppressive Agent

54 citations , February 1994 in “Journal of Investigative Dermatology”

community Still losing ground on finasteride

4 upvotes 2 weeks ago

The user is experiencing hair shedding and loss of density after adjusting finasteride dosage due to side effects and is considering whether to maintain the current dose or increase it. Suggestions include being patient with the current dose, considering adding minoxidil, and possibly trying dutasteride if issues persist.

3 upvotes 1 month ago

The user has been using a combination of dutasteride, minoxidil, and biotin for hair loss but is experiencing a decline in hair condition after initial improvement. They are considering consulting a trichologist and switching from capsule to softgel format for better absorption.

community Still receding on dutasteride after 18 months

in Finasteride/Dutasteride 11 upvotes 1 month ago

A 21-year-old male has been using dutasteride for 18 months and a topical minoxidil/finasteride solution for 2.5 years, but his hairline continues to recede. He is considering switching back to finasteride, as some users suggest increasing the dutasteride dose or adding other treatments like ketoconazole shampoo.

community Still have itchy scalp after 6 months on fin + keto

29 upvotes 4 months ago

The user experiences an itchy scalp despite using finasteride and ketoconazole shampoo for hair loss. Suggestions include trying different shampoos, switching to dutasteride, and using topical treatments for inflammation.

community Stick with it (3 year progress)

in Progress Pictures 228 upvotes 4 months ago

The conversation is about a user's three-year progress in reversing hair loss using daily Dutasteride 0.5 mg and topical Minoxidil, with no side effects. The user emphasizes patience, as significant results were noticed after one year, despite a strong family history of early baldness.

learn Caffeine

Stimulant used in hair shampoos and lotions

Does caffeine stimulate hair growth or only slow hair loss? Caffeine stimulates hair follicles in laboratory cultures, and one open-label, manufacturer-funded trial in 210 men found a 0.2% caffeine topical non-inferior to minoxidil 5% on an anagen-ratio endpoint. A 2025 systematic review found only a few small controlled trials, mostly rated low or very low quality, and none in alopecia areata.

learn KY19382

Is KY19382 safe to use long-term, or is it still considered experimental? KY19382 is still considered experimental and lacks long-term safety data.
How does KY19382 actually stimulate dormant hair follicles to grow again? In mouse and cell studies, KY19382 reactivated hair follicles via Wnt/β-catenin signalling; it has never been tested in humans.

learn sh-Polypeptide-7

Does sh-Polypeptide-7 stimulate hair follicles or reduce scalp inflammation? sh-Polypeptide-7 is the INCI name for a lab-made form of human growth hormone (somatotropin) — not EGF, which is sh-Oligopeptide-1. Growth hormone and IGF-1 signalling is documented in hair follicle biology, but there is no published human trial of sh-Polypeptide-7 applied to the scalp for hair growth or scalp inflammation.

learn Vascular Endothelial Growth Factor

Can products that stimulate Vascular Endothelial Growth Factor (VEGF) improve blood flow to hair follicles? Unproven. Raising VEGF increases vessels around follicles in mice and minoxidil raises VEGF in cultured cells, but no study shows VEGF-marketed products improve scalp blood flow or hair loss in people.
