Polygonum Multiflorum Extract Supports Hair Growth by Elongating Anagen Phase and Abrogating the Effect of Androgen in Cultured Human Dermal Papilla Cells

research Polygonum multiflorum extract support hair growth by elongating anagen phase and abrogating the effect of androgen in cultured human dermal papilla cells

15 citations , May 2020 in “BMC complementary medicine and therapies”

This study found that Polygonum multiflorum extract may promote hair growth by increasing anagen duration and activating dermal papilla cells in human hair follicles, as observed in cultured cell models.

research The mouse hairy ears mutation exhibits an extended growth (anagen) phase in hair follicles and altered Hoxc gene expression in the ears

10 citations , November 2008 in “Veterinary Dermatology”

In this study, the misshaped and hairy ear phenotype in mutant mice was linked to mis-expression of certain Hoxc genes due to a chromosomal inversion.

Adenosine Stimulates Growth of Dermal Papilla and Lengthens the Anagen Phase by Increasing the Cysteine Level via Fibroblast Growth Factors 2 and 7 in an Organ Culture of Mouse Vibrissae Hair Follicles

research Adenosine stimulates growth of dermal papilla and lengthens the anagen phase by increasing the cysteine level via fibroblast growth factors 2 and 7 in an organ culture of mouse vibrissae hair follicles

28 citations , October 2011 in “International Journal of Molecular Medicine”

In this study, adenosine was found to stimulate hair follicle growth in vitro by promoting growth factor expression, β-catenin activation, and downstream signaling pathways.

STAT5 Activation in the Dermal Papilla Is Important for Hair Follicle Growth Phase Induction, Hair Follicle Regeneration, and Wound Healing

research 219 STAT5 activation in the dermal papilla is important for hair follicle growth phase induction, hair follicle regeneration and wound healing

1 citations , August 2016 in “Journal of Investigative Dermatology”

This research reported that STAT5 activation in the dermal papilla plays a crucial role in triggering anagen entry during post-developmental hair follicle cycling.

18-β-Glycyrrhetinic Acid Promotes Hair Growth by Stimulating the Proliferation of Dermal Papilla Cells and Outer Root Sheath Cells, and Extends the Anagen Phase by Inhibiting 5α-Reductase

research 18-β-Glycyrrhetinic Acid Promotes Hair Growth by Stimulating the Proliferation of Dermal Papilla Cells and Outer Root Sheath Cells, and Extends the Anagen Phase by Inhibiting 5α-Reductase

July 2024 in “Biological and Pharmaceutical Bulletin”

This study found that 18-β-Glycyrrhetinic acid, a licorice component, stimulated human hair follicle cell proliferation, inhibited testosterone 5α-reductase, and suppressed TGF-β1, suggesting potential for treating androgenetic alopecia by promoting hair growth and prolonging the anagen phase.

learn Hair Transplant

What happens after a hair transplant? Expect mild swelling and redness, with new hair growth starting in 3 to 6 months.
How long does a hair transplant procedure take? A hair transplant procedure typically takes 4 to 8 hours.

learn Stemoxydine

chemical from L'Oreal that encourages hair to enter growth phase

How does stemoxydine help stimulate new hair growth on the scalp? Stemoxydine stimulates new hair growth by promoting hair follicles to transition from the resting phase to the active growth phase.

learn Follistatin

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

What is follistatin, and how does it influence hair follicle growth and regeneration? Follistatin blocks activin and related growth-inhibiting proteins, which in laboratory and animal work is described as keeping hair follicles in their growth phase; the only verifiable human evidence is a single small 2011 phase 1 injection trial, so follistatin remains experimental and is not an approved hair-loss treatment.

learn Platelet-Rich Plasma

growth factors taken from your blood and injected into your scalp to stimulate hair

What is Platelet-Derived Growth Factor Beta Polypeptide, and how does it help stimulate new hair growth? PDGF-BB is a growth factor that signals to dermal papilla cells and promotes blood-vessel formation; mouse studies report it can push follicles into the growth phase, and human evidence comes only indirectly from PRP trials. No PDGF product is approved for hair restoration and there is no published human trial of PDGF-BB on its own.
