research Abstract 4350: Pharmacodynamic biomarkers: Evaluation of oncology drug target engagement in human plucked scalp and beard hair

April 2023 in “Cancer Research”

This study demonstrated that human plucked hairs can be used as a valuable biomarker to evaluate the pharmacodynamic responses of various chemotherapy agents ex vivo, supporting their potential use for assessing oncology drug target engagement prior to clinical studies.

The G-Protein Coupled Receptor Kinase 2 (GRK2) Orchestrates Hair Follicle Homeostasis

research The G-Protein Couple Receptor Kinase 2 (GRK2) Orchestrates Hair Follicle Homeostasis

April 2024 in “bioRxiv (Cold Spring Harbor Laboratory)”

In a keratinocyte-specific knockout mouse model, this study found that deleting GRK2 disrupted hair follicle homeostasis, causing cyst-like structures, abnormal growth patterns, and eventual hair loss, suggesting potential links to immune-mediated alopecias.

research The circular RNA circNlgnmediates doxorubicin-inducedcardiac remodeling and fibrosis

19 citations , March 2022 in “Molecular therapy. Nucleic acids”

This study found that silencing the circular RNA circNlgn in mice reduced doxorubicin-induced cardiofibrosis and cardiomyocyte apoptosis, suggesting potential therapeutic strategies for minimizing heart-related side effects in cancer treatment.

research Role of Dermal Factors Involved in Regulating the Melanin and Melanogenesis of Mammalian Melanocytes in Normal and Abnormal Skin

April 2024 in “International journal of molecular sciences”

This review examined and discussed the role of dermis-derived factors in the regulation of melanogenesis, noting their significance in both normal and abnormal mammalian skin conditions, suggesting an underexplored area of study compared to dermal and epidermal influences.

research Benzo[c]quinolizin-3-ones: A Novel Class of Potent and Selective Nonsteroidal Inhibitors of Human Steroid 5α-Reductase 1

28 citations , September 2000 in “Journal of Medicinal Chemistry”

This study identified novel compounds as selective inhibitors of the type 1 isoenzyme of 5α-reductase, displaying promising potential for treating DHT-dependent disorders such as acne and androgenic alopecia.

community 100 days on 1 m g. Finasteride

1 upvotes 19 hours ago

The user noticed reduced hair fall and healthier hair after 100 days on 1 mg finasteride. Another user suggested adding minoxidil.

community Non-prescription topical supportive treatments (e.g. caffeine, alfatradiol, The Ordinary Serum, Zix, etc) in addition to the big 3/4???

5 upvotes 4 years ago

Adding non-prescription topicals like alfatradiol and Zix to a standard fin/min/niz regimen may help with scalp inflammation and shedding, but their long-term effectiveness varies. Zix is recommended for reducing scalp inflammation and enhancing the effectiveness of other treatments.

community Can I shift from dutasteride 2.5mg to 0.g back ?

1 upvotes 1 week ago

The conversation is about a user considering switching from 2.5mg to 0.5mg of dutasteride due to hair loss concerns and parental pressure. They are also considering using a hair system if the lower dose doesn't work after four more months.

community Do the more newer gen topical retinoids e.g. tazarotene outperform tretinoin in inducing follicular sulfotransferase activity?

6 upvotes 1 month ago

Tazarotene may outperform tretinoin for hairline treatment with minoxidil, but lacks evidence. Tretinoin is recommended for the scalp, while tazarotene can be used on the face.

community Is anyone here using lower concentrations of topical finasteride (e.g., 0.005-0.05% range) and seeing results?

in Finasteride/Dutasteride 4 upvotes 4 months ago

Users discuss the effectiveness of low-dose topical finasteride (0.005-0.05%) for hair loss, often combined with minoxidil. Some report stable results or new growth, but it's unclear if improvements are due to finasteride or minoxidil.
