research The immunology of the porcine skin and its value as a model for human skin

353 citations , November 2014 in “Molecular immunology”

This review discusses the immune functions of porcine skin and proposes a classification of dendritic cell subsets based on similarities to human skin, but it reports no new clinical results.

research Human Skin is a Steroidogenic Tissue: Steroidogenic Enzymes and Cofactors Are Expressed in Epidermis, Normal Sebocytes, and an Immortalized Sebocyte Cell Line (SEB-1)

289 citations , May 2003 in “Journal of Investigative Dermatology”

This study demonstrates that human skin is capable of steroid hormone synthesis, but its role in androgenic skin disorders like acne and alopecia is yet to be clarified.

research Imaging of zinc oxide nanoparticle penetration in human skin in vitro and in vivo

264 citations , January 2008 in “Journal of biomedical optics”

This study found that ZnO nanoparticles in topical skin products do not penetrate beyond the outer skin layers in humans, suggesting minimal safety concerns for subdermal absorption.

Human Skin Stem Cells and the Aging Process

research Human skin stem cells and the ageing process

143 citations , September 2008 in “Experimental gerontology”

This review discusses the diverse roles and characteristics of epidermal and dermal stem cells in skin regeneration and aging, highlighting their potential applications in regenerative medicine and reports no new clinical results.

research Endocannabinoids limit excessive mast cell maturation and activation in human skin

124 citations , January 2012 in “Journal of Allergy and Clinical Immunology”

This study found that activation of cannabinoid 1 receptors in human scalp hair follicles may limit excessive mast cell activation and maturation, suggesting a potential therapeutic strategy for managing MC-dependent skin diseases.

community Hair and normal skin created from human pluripotent stem cells for the first time

86 upvotes 6 years ago

Human pluripotent stem cells have been used to create hair and skin, potentially offering a new solution for baldness. A user also mentioned starting finasteride but experiencing unexpected hair thinning.

community Is it possible to transplant mice skin into human body?

in Transplants 47 upvotes 10 months ago

Transplanting mice skin to humans is not feasible due to immune rejection, but some suggest genetic modification or immune suppression could make it possible. Xenograft hair transplants are discouraged.

community Functional hair follicles grown from stem cells: Scientists have created natural-looking hair that grows through the skin using human induced pluripotent stem cells (iPSCs), a major scientific achievement that could revolutionize the hair growth industry.

171 upvotes 7 years ago

Scientists have grown natural-looking hair from stem cells, potentially revolutionizing hair growth treatments. Concerns include cost, DHT resistance, and the need for future procedures.

community Topical Metformin for Hair Transplant donor area skin/hair regeneration?

4 upvotes 1 year ago

Topical Metformin shows potential for regenerating hair follicles and minimizing scarring in hair transplant donor areas, similar to Verteporfin but without its side effects. The discussion suggests considering Metformin for post-hair transplant care, though more human trials are needed.

community New study suggests hair regrowth on wounded and bald skin may be possible

4 upvotes 7 years ago

Hair regrowth on wounded and bald skin may be possible by activating the sonic hedgehog gene, leading to hair regrowth in mice. The findings are promising but may not directly apply to humans.

learn Fluocinolone

Can long-term use of Fluocinolone affect the health of hair follicles? There is no long-term human trial measuring what topical fluocinolone does to hair follicles; what is documented is the label's warning about skin atrophy with prolonged use, plus a 2007 mouse study suggesting hair-follicle bulge stem cells do not repair steroid-induced atrophy.
Is Fluocinolone a treatment for hair loss itself or just for calming scalp irritation? Fluocinolone acetonide is a prescription corticosteroid approved for inflammatory skin conditions, not for hair loss; no published human trial has measured hair regrowth with it, so at most it may help indirectly by calming an inflamed scalp.

learn GHK-Cu

a copper peptide showing promise in both regrowth and reversing gray hair

What is GHK-Cu and why is it said to be a "miracle" for hair? GHK-Cu is a copper peptide studied mainly for wound healing and skin repair; for hair loss the evidence stops at cell-culture and animal work, and no published human trial has tested it for androgenetic alopecia.

learn Peppermint

herb and oil thought to stimulate skin and hair

learn Latanoprost

Can latanoprost be safely applied to the scalp, or is it only for eyelashes? Latanoprost is not approved for use on the scalp and its safety there has not been established: the only human scalp evidence is one 24-week pilot trial in 16 men, and clinicians flag irritation, skin darkening and unknown absorption over a large area as open risks.

learn Folic acid

Is there a difference between taking folic acid supplements and using folic acid in topical hair products? Oral folic acid uses the body's normal absorption route and can correct a measured deficiency, but no published trial shows it treats hair loss; topical folic acid has no human evidence for hair growth and struggles to cross the skin barrier at all.

glycoprotein that inhibits TGF-β and promotes hair growth by antagonizing activin
