Single-Cell Transcriptomics Reveals Hair Growth Retardation Mediated by Aberrant Connective Tissue Sheath Contraction in Male Androgenetic Alopecia

research Single-cell transcriptomics reveals hair growth retardation mediated by aberrant connective tissue sheath contraction in male androgenetic alopecia

February 2026 in “Nature Communications”

This study combined spatial and single-cell transcriptomics to identify that hypercontractility of the connective tissue sheath activates PIEZO1 in hair follicles, leading to miniaturization in male androgenetic alopecia, and found that inhibiting this contraction improves hair growth in models.

research Aberrant expression of epidermal growth factor receptor in aural cholesteatoma

48 citations , March 1993 in “The Laryngoscope”

This study found that EGF receptors are aberrantly regulated and persist in cholesteatoma epithelium, suggesting a hyperproliferative character compared to normal human skin.

research Delayed Cutaneous Wound Healing and Aberrant Expression of Hair Follicle Stem Cell Markers in Mice Selectively Lacking Ctip2 in Epidermis

52 citations , February 2012 in “PloS one”

This study found that the absence of Ctip2 in epidermal keratinocytes led to impaired wound healing in mice, affecting cell migration, proliferation, and hair follicle stem cell maintenance.

Aberrant Connective Tissue Sheath Contraction Drives Premature Hair Follicle Regression by Inducing Progenitor Cell Depletion in Androgenetic Alopecia

research Aberrant connective tissue sheath contraction drives premature hair follicle regression by inducing progenitor cell depletion in androgenetic alopecia

December 2023 in “bioRxiv (Cold Spring Harbor Laboratory)”

This study found that targeting connective tissue sheath contraction with an MLCK inhibitor may improve hair growth in androgenetic alopecia by reducing premature hair regression caused by ectopic apoptosis of hair follicle progenitor cells.

research Silicon-Related Syndrome in Dialysis Patients

21 citations , January 1997 in “Nephron”

In this study, two dialysis patients with high plasma silicon levels exhibited symptoms like painful skin eruptions and unusual hair growth, suggesting silicon may influence calcium metabolism similarly to aluminum.

community DHT Isn’t the Only Factor in Hair Loss and That Might Be the Key to a Real Cure

373 upvotes 6 months ago

Hair loss involves more than just DHT, with genetic factors like TRPS affecting hair follicles. Treatments such as Amplifica's AMP-601 and AMP-303 target stem cells for potential hair growth solutions.

community Why not move miniaturized hair follicles somewhere else to treat them? Alternative to hair cloning?

4 upvotes 1 year ago

Exploring the idea of transplanting miniaturized hair follicles to healthier areas to potentially reverse hair loss, with concerns about DHT sensitivity and scar tissue formation. The conversation also humorously considers using mice for hair growth experiments.

community Why are people so negative regarding Clascoterone (Breezula)?

20 upvotes 3 months ago

Clascoterone (Breezula) shows promising hair growth results, but skepticism remains due to past disappointments with new treatments. It may be a good alternative for those who can't tolerate finasteride or dutasteride, and can potentially be combined with them and minoxidil for better results.

community Prolactin the Cause of Hair Loss? ABS-201 the Cure?

29 upvotes 2 months ago

Prolactin may contribute to hair loss, but targeting its receptor won't cure androgenetic alopecia. ABS-201 could be a useful alternative or adjuvant therapy, similar to JAK inhibitors, but not more effective than HMI-115.

community How Veradermics secured a total of $220 million in series B and C financing for oral minoxidil, I will never understand.....

in Chat 38 upvotes 10 months ago

Veradermics' oral minoxidil shows promise for hair regrowth, with some users reporting significant improvements, while Pelage's PP405 results are less convincing and lack transparency. There is skepticism about both treatments' long-term effectiveness and potential side effects.

Hair transplantation moves DHT-resistant follicles from a donor area (back and sides of the scalp) into thinning or bald areas. The transplanted hair is generally permanent, though surrounding native hair can keep thinning.
