research The Extraction of Keratin from Human Hair Waste for Copolymerization with Nitrile Butadiene Rubber

August 2023 in “Journal of Student Research”

This study found that incorporating keratin extracted from hair into NBR modestly enhanced the mechanical properties and biodegradability of the rubber.

research Effect of Waste Human Hair Fibers on Shear Behavior of Sand in Dry and Saturated Conditions

9 citations , July 2018 in “Journal of Testing and Evaluation”

This study found that human hair fibers significantly improve the shear behavior of dry sand, but under saturated conditions, the reinforcement sustains shear strength similar to unreinforced sand.

research Wool and Hair Waste as Nutrient Source for High-value Crops

July 2005 in “HortScience”

This study found that adding sheep wool-waste or human hair-waste to soil increased yields and secondary metabolites in various crops and supported up to five harvests without additional fertilizers, though it decreased mycorrhizae colonization.

research Formation and Characterization of Hollow Microtubes by Thermal Treatment of Human Hair

2 citations , March 2018 in “ACS Sustainable Chemistry & Engineering”

This study found that stepwise thermal treatment of human hair waste at temperatures from 200 to 450 °C produced hollow microtubes, with structure changes influenced by temperature, core degradation, and cortex melting.

research Valorization of Unconventional Hair Waste: Unlocking Opportunities in Materials and Chemical Engineering

November 2025 in “Journal of Natural Fibers”

This study reviews the potential to repurpose human hair waste, often discarded from places like barber shops and hospitals, into valuable raw materials for chemical and materials science applications, despite existing challenges in its utilization.

community [Nov 2019] The peptide AC 2 isolated from Bacillus-treated Trapa japonica fruit extract rescues DHT (dihydrotestosterone)-treated human dermal papilla cells and mediates mTORC1 signaling for autophagy and apoptosis suppression

23 upvotes 6 years ago

A peptide from Japanese water chestnut fruit may help with hair loss by suppressing DHT's effect on hair follicle cell death, potentially serving as a finasteride alternative. The treatment's effectiveness and safety in humans remain uncertain.

community Most Underrated Hack for Hair Loss is Water

in Chat 68 upvotes 8 months ago

Filtered shower heads may improve scalp and hair health but do not affect male pattern baldness (MPB). Genetics and factors like DHT and scalp tension are more significant in hair loss.

community Hair loss is holding me back from enjoying life and I'm wasting away my youth

279 upvotes 6 months ago

A 31-year-old man feels depressed due to hair loss, using topical finasteride and previously tried minoxidil. Others suggest treatments like finasteride, minoxidil, hair transplants, or embracing baldness, highlighting the importance of mental health and self-acceptance.

community HairClone (UK) finally begins offering its Dermal Papilla Cell Hair Multiplication procedure to humans. In Guatemala.

149 upvotes 7 months ago

HairClone is offering a Dermal Papilla Cell Hair Multiplication procedure in Guatemala, raising questions about its effectiveness and regulatory reasons for the location. Users express skepticism and curiosity about the treatment's success and potential costs.

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.

Oil from the neem tree, used in traditional remedies

learn Dutasteride

5-alpha reductase inhibitor that blocks both enzyme types, a stronger DHT blocker than finasteride

learn Ecklonia Cava

Can Ecklonia Cava reactivate dormant hair follicles and support new growth? No human study has tested whether Ecklonia cava reactivates hair follicles; the evidence comes from cultured cells, cultured follicles and mice.
Can Ecklonia Cava be used as a preventive treatment for early signs of hair thinning? No human trial has tested Ecklonia cava for hair loss, so it cannot be called preventive; the evidence is mouse studies and cell cultures suggesting antioxidant activity and 5-alpha-reductase inhibition in the lab.

learn RU58841

Will I lose my hair if I stop using RU58841? (Spoiler: I might.) There is no published human trial of stopping RU58841; community members commonly report shedding within weeks to months, and androgen biology suggests miniaturization would resume once the topical anti-androgen is withdrawn.

learn Castor oil

Does castor oil make hair grow or is it just a myth? There is no published human trial showing castor oil grows hair. It can make hair look and feel better by reducing breakage and adding shine, which is easily mistaken for growth, and it is not approved anywhere as a hair loss treatment.

learn Redensyl

Does Redensyl prevent hair loss or only help when there's already visible hair loss? The only Redensyl-specific human data is a small, unpublished manufacturer study in men who already had androgenetic alopecia; published trials test multi-ingredient products, and no evidence supports using it to prevent hair loss.
