research A new approach to the bending properties of hair fibers.

2 citations , January 2002 in “PubMed”

This study introduces a new test using a pendulum device to assess the bending stiffness of hair fibers, which can evaluate the effects of different hair treatments.

research Physical Properties of Human Hair. 1. Evaluation of Bending Stress by Measuring the Major and the Minor Axis of Human Hair.

10 citations , January 2002 in “Nihon Keshouhin Gijutsushakaishi/Journal of S C C./Nihon Keshouhin Gijutsushakai kaishi”

This study found that the cuticle layer of hair contributes approximately 60% to bending stress, highlighting its significant role in the mechanical properties of hair stiffness.

research The Binding of Small Molecules and Polymers to Keratin and Their Effects on the Physicochemical and Surface Properties of Hair Fibers

7 citations , January 1981 in “Springer eBooks”

This model study describes how interactions between hair keratin and various materials alter hair's physical and mechanical properties by affecting noncovalent bonds.

research Unchanged androgen-binding properties of sex hormone-binding globulin in male patients with liver cirrhosis

29 citations , January 2006 in “Clinical chemistry and laboratory medicine”

This study found that male liver cirrhosis patients have higher estradiol levels and lower dehydroepiandrosterone sulfate, leading to hormonal imbalances favoring estradiol, but without changing sex hormone-binding globulin's binding properties.

research Development of a three‐point cantilever bending technique to study the mechanical properties of hair styling ingredients

1 citations , December 2022 in “Skin Research and Technology”

This article provides guidelines and indices for a three-point cantilever bending test to measure mechanical properties of hair treated with both conventional and naturally-derived styling polymers, reporting no new experimental results.

community Almost 4 months on GHK-Cu hair growth progress

in Progress Pictures 41 upvotes 5 months ago

OP noticed fuller and thicker hair after almost 4 months of using GHK-Cu, a copper-binding peptide, through subcutaneous injections. Some users were skeptical, questioning the authenticity and potential commercial intent behind the post.

community The mechanism of androgenic alopecia

36 upvotes 11 months ago

DHT may inhibit hair growth by affecting mitochondrial function, leading to hair follicle miniaturization. Treatments like minoxidil and PP405 may promote hair growth by altering metabolic pathways, potentially counteracting DHT's effects.

community Better Than Minoxidil? Topical Sodium Valproate

50 upvotes 1 year ago

Topical sodium valproate may promote hair growth by inhibiting GSK3β, allowing beta-catenin to proliferate, but it has potential side effects and requires more research. The conversation also mentions skepticism about a product called Vdphlo1, which includes sodium valproate and other ingredients.

community Green tea/ soy Isoflavones supplements for MPB

4 upvotes 5 years ago

Green tea extract and soy isoflavones may help with hair loss by inhibiting DHT and providing additional health benefits. Combining these with finasteride and possibly using nizoral shampoo could enhance effectiveness in managing hair loss.

community Grow Gorgeous Intense Hair Density Serum, 2.02 fl oz, 2-pack from Costco

1 year ago

The user is considering using "Grow Gorgeous Intense Hair Density Serum" alongside Minoxidil and is currently taking Finasteride. Some users doubt the serum's effectiveness, while others suggest it may help with hair strength and thickness, but opinions are mixed.
