research Parathyroid hormone linked to a collagen binding domain promotes hair growth in a mouse model of chemotherapy-induced alopecia in a dose-dependent manner

8 citations , April 2014 in “Anti-Cancer Drugs”

In this study, PTH–CBD displayed dose-dependent effects in reducing hair loss and enhancing hair regrowth in a mouse model of chemotherapy-induced alopecia.

research Hair-Cycle-Dependent Expression of Parathyroid Hormone-Related Protein and its Type I Receptor: Evidence for Regulation at the Anagen to Catagen Transition

52 citations , May 2003 in “The journal of investigative dermatology/Journal of investigative dermatology”

This study found that overexpression of parathyroid hormone-related protein in mice resulted in 30–40% shorter hair due to premature transition into the catagen phase of the hair cycle.

research Androgens trigger different growth responses in genetically identical human hair follicles in organ culture that reflect their epigenetic diversity in life

19 citations , October 2017 in “The FASEB Journal”

This study established an androgen-responsive human organ culture model using hair follicles, demonstrating that women's intermediate facial follicles grow more hair in response to men's higher androgen levels.

research Endocrine controls of primary adult human stem cell biology: Thyroid hormones stimulate keratin 15 expression, apoptosis, and differentiation in human hair follicle epithelial stem cells in situ and in vitro

42 citations , July 2010 in “European Journal of Cell Biology”

This study found that thyroid hormones T3 and T4 enhance keratin 15 promoter activity and stimulate CD200 expression in epithelial stem cells from human scalp hair follicles, affecting their growth and differentiation.

research Ability to culture dermal papilla cells from red deer (Cervus elaphus) hair follicles with differing hormonal responses in vivo offers a new model for studying the control of hair follicle biology

16 citations , August 1996 in “The journal of experimental zoology/Journal of experimental zoology”

This study suggests that red deer stags provide a novel model for investigating hormonal regulation of hair growth due to the different cell growth rates in hair follicles during breeding and nonbreeding seasons.

community Why does the same hormone grow your beard and destroy your hairline?

44 upvotes 4 months ago

DHT promotes beard growth but causes scalp hair loss due to inflammation and fibrosis. Treatments like finasteride and minoxidil help with hormonal signals and blood flow but don't address underlying inflammation.

community Sugars ARE important for hair growth | Glycosaminoglycans as Hair Growth Stimulant

74 upvotes 2 years ago

Glycosaminoglycans are important for hair growth, and combining minoxidil with tretinoin and Biopeptide-CL may enhance hair growth by boosting glycosaminoglycan levels and improving the hair follicle environment. Users discussed the potential effectiveness and future of these treatments.

community Tropical growth stimulants other than minoxidil

10 upvotes 2 years ago

The conversation discusses alternative hair growth treatments to minoxidil, including Stemoxydine, Tretinoin, adenosine, Baicalin, castor oil, Latanoprost/bimatoprost, and Redensyl. Users share their experiences and opinions on the efficacy of these treatments.

community 5 Months on topical Fin/Min progress: grows hair and boobs

in Progress Pictures 159 upvotes 11 months ago

The user experienced significant hair growth using topical finasteride and minoxidil but noticed nipple changes, suggesting early gynecomastia. They plan to stop the treatment and consider blood work to check hormonal balance.

community How long does it take after an environmental / lifestyle change for hair loss to actually slow down?

5 upvotes 11 months ago

Lifestyle changes may not significantly impact hair loss, as factors like DHT and genetics play a larger role. Some users suggest treatments like finasteride, dutasteride, and microneedling for hair growth.
