research Epidermal growth factor delays the development of the epidermis and hair follicles of mice during growth of the first coat

72 citations , January 1983 in “The Anatomical Record”

This study found that epidermal growth factor treatment in male mice delayed normal skin development, inhibiting hair growth and follicle development by maintaining birth-level cell proliferation and differentiation for several days.

research Trypsin-induced follicular papilla apoptosis results in delayed hair growth and pigmentation

29 citations , April 1997 in “Developmental Dynamics”

This study found that topical trypsin application after hair removal in mice led to cell death at the follicular papilla, which delayed hair growth and pigmentation.

research Trypsin‐induced follicular papilla apoptosis results in delayed hair growth and pigmentation

3 citations , April 1997 in “Developmental Dynamics”

In this study, topical trypsin treatment following depilation in a mouse model induced cell death at the follicular papilla, delaying hair growth and pigmentation.

ATP-Competitive mTOR Kinase Inhibitors Delay Plant Growth by Triggering Early Differentiation of Meristematic Cells Without Developmental Patterning Change

research ATP-competitive mTOR kinase inhibitors delay plant growth by triggering early differentiation of meristematic cells but no developmental patterning change

161 citations , August 2013 in “Journal of experimental botany”

This study found that specific ATP-competitive TOR inhibitors (asTORis) decrease root growth in Arabidopsis thaliana in a dose-dependent manner, similar to their effects on mammalian cells.

Hair Growth Induction by the Tellurium Immunomodulator AS101: Association with Delayed Terminal Differentiation of Follicular Keratinocytes and Ras-Dependent Up-Regulation of KGF Expression

research Hair growth induction by the tellurium immunomodulator AS101: association with delayed terminal differentiation of follicular keratinocytes and ras‐dependent up‐regulation of KGF expression

51 citations , December 2003 in “The FASEB Journal”

This study reports that AS101 induced hair growth in mice and suggests potential for treating chemotherapy-induced alopecia in humans, which was observed in case report studies with three adolescents.

community Sprinkle that PP405 on my scalp like I sprinkle salt on my stake

119 upvotes 1 year ago

PP405 shows promise for hair growth with significant results after 4 weeks, but skepticism exists due to its unavailability. Some users are hopeful for its potential, while others express concerns about side effects and market release delays.

community Why did this recent research paper from professor Tsuji lab in Japan largely go unnoticed by this sub? Isn't this discovery huge? (hair cloning)

35 upvotes 4 months ago

A recent discovery in hair cloning identified a previously unknown cell type essential for hair follicle growth, which could potentially make lab-grown hair viable if translated to humans. However, skepticism remains due to past delays and the challenges of replicating results in humans and making the process affordable.

community Breezula phase 3 results where are youuuu👀

17 upvotes 11 months ago

Breezula's phase 3 results are expected soon, but its release is likely delayed until 2027 or 2028. The discussion highlights the need for more hair growth stimulants like AMP-303 and PP-405, as current treatments like Dutasteride effectively stop hair loss but don't regrow hair.

community Han Bio Aims for Phase 1 Clinical Trials in 2027 after successful hair growth in mice

in Research/Science 248 upvotes 1 year ago

Han Bio plans to start Phase 1 clinical trials for a hair growth treatment in 2027 after successful results in mice. Many users express skepticism about the effectiveness of treatments that work on mice but not on humans, and discuss existing treatments like finasteride and minoxidil.

community Now with the delay of GTA 6 to November 2026 and potentially another delay to 2027, we could actually be getting PP405 before GTA 6.

in Chat 177 upvotes 10 months ago

A potential baldness cure, possibly PP405, might be available before the release of GTA 6, which is delayed to 2026 or 2027. There is skepticism about the effectiveness and release timeline of PP405.

learn Caffeine

Does caffeine stimulate hair growth or only slow hair loss? Caffeine stimulates hair follicles in laboratory cultures, and one open-label trial in 210 men found a 0.2% caffeine topical non-inferior to minoxidil 5% on an anagen-ratio endpoint; there is no placebo-controlled evidence that it regrows hair, and none at all in alopecia areata or telogen effluvium.

learn Lavender

Does lavender promote hair growth or just soothe an irritated scalp? Lavender may promote hair growth and soothe an irritated scalp.

learn Bimatoprost

Can a lash-growth serum like bimatoprost actually work for your scalp? Bimatoprost (Latisse) is approved for eyelashes, not the scalp; two Allergan phase 2 trials in men with androgenetic alopecia posted results to ClinicalTrials.gov but were never published in a peer-reviewed journal, so scalp use remains off-label and experimental.

learn Dexpanthenol

Does dexpanthenol promote hair growth? Dexpanthenol improves hair moisture and strength but does not directly promote hair growth.

learn horsetail extract

How does horsetail extract support hair growth — is it the silica, the antioxidants, or both? Horsetail extract supports hair growth primarily through its silica content.
