research Cosmeceuticals: peptides, proteins, and growth factors

67 citations , May 2016 in “Journal of Cosmetic Dermatology”

This study describes commonly used peptides, proteins, and growth factors in cosmeceuticals and discusses their potential benefits in dermatology, though their long-term effects remain unconfirmed.

research A Randomized Study of Biomimetic Peptides Efficacy and Impact on the Growth Factors Expression in the Hair Follicles of Patients with Telogen Effluvium

January 2018 in “journal of applied pharmaceutical science”

Biomimetic peptides improved hair growth and increased growth factors in hair follicles for hair loss patients.

research Hair-Growth-Promoting Effects of the Fish Collagen Peptide in Human Dermal Papilla Cells and C57BL/6 Mice Modulating Wnt/β-Catenin and BMP Signaling Pathways

October 2022 in “International Journal of Molecular Sciences”

This study found that collagen peptides from Mozambique tilapia significantly promoted hair regrowth and increased the proliferation of hair growth factors in vitro and in vivo, suggesting potential as supplements for hair loss prevention.

research Co-delivery of bioactive peptides by nanoliposomes for promotion of hair growth

4 citations , May 2022 in “Journal of Drug Delivery Science and Technology”

This research observed that nanoliposomes delivering a combination of bioactive peptides significantly promoted hair growth in vitro and in vivo by enhancing the proliferation and function of hair growth-targeted cells in C57BL/6 mice, suggesting a promising approach for treating androgenetic alopecia.

research RGDSP-functionalized peptide hydrogel stimulates growth factor secretion via integrin αv/PI3K/AKT axis for improved wound healing by human amniotic mesenchymal stem cells

6 citations , October 2024 in “Frontiers in Bioengineering and Biotechnology”

This study reported that the use of composite RGDmix hydrogel improved the survival and proliferation of human amniotic mesenchymal stem cells and increased growth factor expression, enhancing wound healing through the RGDSP/integrin αv/PI3K/AKT signaling pathway.

community The use of peptides to enhance hair growth from wounding

4 upvotes 9 years ago

The conversation discusses using peptides BPC-157 and TB-500, combined with microneedling, to potentially enhance hair regrowth. The user plans to try BPC-157 due to its lower cost and reports of hair growth, despite limited human trials and concerns about side effects from other treatments like minoxidil and finasteride.

community Any experience with Copper Peptides or micro infusion systems for hair growth?

4 upvotes 8 months ago

The conversation is about using copper peptides and micro infusion systems for hair growth. The original poster is currently using topical minoxidil and oral finasteride.

community Collagen peptides: Yay or nay?

5 upvotes 6 years ago

Collagen peptides may help with hair growth, but results vary; some users noticed less hair fall and improved nail strength. Minoxidil is suggested for regaining hair thickness lost from accutane.

community AHK-cu peptides experiences and sources to buy

5 upvotes 1 year ago

AHK-cu peptides are discussed for hair growth, with users comparing them to GHK-cu peptides and sharing sources to buy. AHK-cu is noted as more expensive, and users express interest in finding cheaper, reliable vendors.

community GHK-Cu peptide injections - what is your experience?

13 upvotes 6 months ago

GHK-Cu peptide injections are discussed for hair growth, but users report mixed results and suggest focusing on DHT management first. Some users combine GHK-Cu with treatments like Minoxidil and Dutasteride, but emphasize its benefits for skin rather than hair.

learn Thymosin Beta 4

How is Thymosin Beta 4 typically incorporated into experimental or advanced hair growth products? Thymosin Beta 4 is not an ingredient in any approved hair-loss product; it is an unapproved research peptide sold online as TB-500, which the FDA flags for safety risks. Hair studies are in rats and mice only, with no human trials, and animal studies link Tβ4 to tumour spread.

learn GHK-Cu

Copper peptide used in skin and hair cosmetics

learn Osteopontin

What role does Osteopontin play in protecting and repairing hair follicles? In mouse studies osteopontin switched on hair stem cells, but an osteopontin-derived peptide suppressed growth in human scalp tissue. Whether it protects human follicles is unknown.
Is Osteopontin more effective in topical treatments or oral supplements for hair loss? Neither route has been tested: there is no published human trial of topical or oral osteopontin for hair loss. The evidence is preclinical, and it points both ways — injected osteopontin promoted hair growth in mice, while an osteopontin-derived peptide suppressed growth in human scalp tissue and its authors proposed it for unwanted hair.

learn Follistatin

Protein that blocks activin, a growth-regulating signal

learn Epidermal Growth Factor

learn Caffeine

Does caffeine stimulate hair growth or only slow hair loss? Caffeine stimulates hair follicles in laboratory cultures, and one open-label, manufacturer-funded trial in 210 men found a 0.2% caffeine topical non-inferior to minoxidil 5% on an anagen-ratio endpoint. A 2025 systematic review found only a few small controlled trials, mostly rated low or very low quality, and none in alopecia areata.

learn Lavender

Does lavender promote hair growth or just soothe an irritated scalp? A 2016 study found more hair growth in mice treated with lavender oil, but no trial has tested lavender alone for hair loss in people. Lavender oil can cause skin allergy, and case reports link lavender products to breast growth in children.
