Glossary Human Scalp Hair Follicles

tiny skin structures on the scalp where hair grows

Human Scalp Hair Follicles are tiny, tunnel-like structures in the skin of the scalp from which hair grows. Each follicle anchors a single hair into the skin and is responsible for the hair's growth cycle, which includes phases of growth (anagen), rest (telogen), and shedding (catagen). These follicles are crucial for hair regeneration and are influenced by various factors, including genetics, hormones, and environmental conditions.

research Description of the Intrafollicular Delivery of Large Molecular Weight Molecules to Follicles of Human Scalp Skin In Vitro

47 citations , September 1997 in “Journal of Pharmaceutical Sciences”

This study found that cationic lipid-based formulations enhanced the delivery of large molecules into hair follicles in human scalp skin, with potential to reach pharmacologically active concentrations in the hair bulb.

research Ultrastructural Localization and Quantification of Extracellular Calcium Binding Sites in Mouse Vibrissa and Human Scalp Follicles

1 citations , January 1993 in “Skin Pharmacology and Physiology”

This study found that an extracellular calcium binding site gradient exists in mouse vibrissa and human scalp follicles, but is not significantly affected by hair growth-altering drugs or epidermal growth factor.

research Connective tissue sheath of hair follicle is a major source of dermal type I procollagen in human scalp

4 citations , September 2012 in “Journal of dermatological science”

The hair follicle's connective tissue is a key source of a certain collagen in human scalp skin.

research Industrial-scale processing of activated platelet-rich plasma from specific pathogen-free pigs and its effect on promoting human hair follicle dermal papilla cell cultivation

February 2017 in “Spectrum Research Repository (Concordia University)”

This study confirmed porcine PRP's commercial viability as a fetal bovine serum replacement, showing higher growth factor levels and stability, without increasing human follicle dermal papilla cell proliferation compared to FBS.

research Human Scalp Hair Follicles Express Prostaglandin E2 Lipid Mediator and Receptors For Pge2

September 2013

This study found that isolated human scalp hair follicles express PGE2 genes and EP2 protein, suggesting PGE2 may play a crucial role in regulating hair growth.

community Chinese reseachers successfully create hair follicles in-vitrofor autologous transplantation in vivo

29 upvotes 1 year ago

Chinese researchers have successfully created hair follicles in vitro, potentially offering unlimited hair for transplantation and a cure for hair loss. They plan to test these follicles in vivo on human scalps.

community Scalp inflammation cleared after stopping "spoiled" milk - what about follicles,shedding?

4 upvotes 6 months ago

Switching milk brands cleared scalp inflammation and other symptoms, but hair shedding continues. The user hopes shedding will stop as hair cycles progress.

community Weed/THC effects on hair growth/hair loss, and vitality of organ-culture human follicle studies (research review)

4 upvotes 1 year ago

Cannabis and THC may have mixed effects on hair, with some studies suggesting potential negative impacts on hair growth in isolated hair follicles, but these results are hard to apply to living humans. Treatments like minoxidil and finasteride are commonly used for hair loss, and the effects of cannabis might be neutral or vary based on individual factors.

community Scientists have found that a naturally occurring sugar in humans and animals could be used as a topical treatment for male pattern baldness | In the study, mice received 2dDR-SA gel for 21 days, resulting in greater number of blood vessels and an increase in hair follicle length and denseness

644 upvotes 2 years ago

Scientists discovered a sugar gel, 2dDR-SA, that increased hair growth in mice. Users discussed its potential, comparing it to other treatments like Minoxidil and finasteride.

community A new study by Deng and colleagues set out to explore differences between balding and non balding scalps...

39 upvotes 4 years ago

Balding scalps have more androgen receptors, leading to increased TGF-beta, which causes blood vessel loss and hair follicle miniaturization. Blocking androgen signaling and TGF-beta may help prevent hair loss.

learn sh-Polypeptide-7

How does sh-Polypeptide-7 help stimulate hair follicle activity or reduce scalp inflammation? sh-Polypeptide-7 is the INCI name for a lab-made form of human growth hormone (somatotropin) — not EGF, which is sh-Oligopeptide-1. Growth hormone and IGF-1 signalling is documented in hair follicle biology, but there is no published human trial of sh-Polypeptide-7 applied to the scalp for hair growth or scalp inflammation.

learn Osteopontin

signaling protein that, when suppressed, may grow hair by reducing inflammation and stem cell loss

learn Thymosin Beta 4

learn Bicalutamide

What results can you expect from using bicalutamide on your scalp? There is no published human study of bicalutamide applied to the scalp for hair loss, no licensed topical product and no established dose, so no result can be predicted from it. The evidence that exists is for the oral tablet in women, which is a prescription drug requiring liver monitoring and contraindicated in pregnancy.

learn Rapamycin

Is rapamycin safe for long-term use on the scalp, or should it be used in cycles? There is no published human trial of topical rapamycin on the scalp, so nobody knows whether long-term use is safe; the idea of cycling it comes from community practice and theory, not from any study or guideline, and rapamycin for hair loss is an off-label use of a prescription immunosuppressant.

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 capsicum

How does capsicum improve scalp circulation and boost growth? Capsaicin dilates blood vessels through TRPV1 activation, so capsicum is expected to raise scalp blood flow, but every human hair-loss study used it inside a multi-ingredient formula — and the strongest one gave it orally, not on the scalp — so its effect on hair by itself is unproven, and it is a known skin irritant.
