Glossary Model organism

non-human species used to study biological processes

A model organism is a non-human species that is extensively studied to understand particular biological processes. Researchers use these organisms, such as mice, fruit flies, or zebrafish, because they share many genetic similarities with humans and have shorter life cycles, making them ideal for experiments that can provide insights into human biology, including hair growth and alopecia.

research Hierarchical patterning modes orchestrate hair follicle morphogenesis

149 citations , July 2017 in “PLoS Biology”

This study found that hair follicle patterning in development may arise from a combination of epidermal prepattern signals and mesenchymal self-organisation, with fibroblast growth factor and bone morphogenetic protein activities playing key roles.

research Redefining the Skin Barrier: A Microbiome‐Integrated Multilayered Defense Model

1 citations , July 2025 in “Barrier Immunity”

This review synthesizes existing research on the multilayered defense system of the skin, highlighting how physical, chemical, immune, and microbial barriers work together to maintain skin health, with disruptions in one often leading to broader barrier dysfunctions.

research Do Changes in Chromosomes Cause Aging?

50 citations , July 1996 in “Cell”

This review discusses genetic and epigenetic mechanisms that may contribute to aging and presents models suggesting that chromosomal changes could play a key role in the aging process; it reports no new experimental findings.

research Establishment of an in vitro hairless guinea pig dermal model

March 2026 in “PLoS ONE”

This research observed that hairless guinea pig dermal fibroblasts were more sensitive to a toxic exposure than human dermal fibroblasts, suggesting that guinea pigs might serve as an intermediate model for translating in vitro findings to whole organisms.

Characterization, Genomic Organization, Expression, and Function of the mEphA1 Receptor Tyrosine Kinase

research Characterisation, genomic organisation, expression and function of the mEphA1 receptor Tyrosine Kinase

April 2007

This research investigated the role of EphA1 in embryonic and adult tissues, generating mouse models suggesting potential links to skin and colon cancer, sepsis, and post-traumatic injury.

community If we can clone a sheep why we can't cure baldness till now

in Research/Science 181 upvotes 1 year ago

Hair loss treatments like Minoxidil, finasteride, and stem cell therapies exist, but a complete cure is hindered by genetic complexity and market dynamics. Cloning hair follicles is considered a potential solution, but it's currently not feasible.

community Dutasteride- what I think is realistic success

in Treatment 34 upvotes 1 month ago

The user experienced hair regrowth using minoxidil and finasteride, later switching to dutasteride with continued improvement. They reported no side effects and emphasized the importance of consistency in treatment.

community DHT reduction in the scalp for all doses of dutasteride is now available.

in Finasteride/Dutasteride 357 upvotes 1 year ago

Higher doses of dutasteride reduce scalp DHT more effectively than finasteride, but have diminishing returns after 3mg daily and may cause more side effects. Combining dutasteride with topical minoxidil can enhance results, but using both finasteride and dutasteride together is unnecessary.

community My husband has experienced depression and suicidal thoughts from finasteride

32 upvotes 1 month ago

Finasteride caused depression and suicidal thoughts in OP's husband, leading him to stop the medication. He is seeing a doctor for a full hormone panel and psychiatric referral to address these issues.

community Is this true? It can be a major breakthrough

1008 upvotes 5 months ago

Deoxyribose sugar gel may stimulate hair regrowth similarly to minoxidil by enhancing blood supply and follicle activity. Human trials are necessary, and current products have mixed results.
