research Human scalp hair: geometry, biochemistry, growth parameters and mechanical characteristics

January 2016 in “Belarusian State Pedagogical University repository (Belarusian State Pedagogical University)”

This research suggests that geometric classification of hair into fewer groups may be more reliable and useful for studying hair characteristics, rather than racial descriptions, especially in medical and forensic applications.

Reimagining Hair Science: A New Approach to Classify Curly Hair Phenotypes via New Quantitative Geometrical and Structural Mechanical Parameters

research Reimagining Hair Science: A New Approach to Classify Curly Hair Phenotypes via New Quantitative Geometrical & Structural Mechanical Parameters

November 2022

This study used quantitative methods to identify new geometric and mechanical parameters of curly and kinky/coily hair, aiming to improve classification and develop better personal care products for these hair types.

research Reimagining Hair Science: A New Approach to Classify Curly Hair Phenotypes via New Quantitative Geometric and Structural Mechanical Parameters

May 2023 in “Accounts of chemical research”

This study aimed to identify new quantitative geometric and mechanical parameters for curly and kinky hair using various microscopy and mechanical analysis methods, revealing correlations between hair fiber geometry and mechanical performance to enhance personal care product development and promote cultural inclusion.

research Fractal geometry and topology abstracted from hair fibers

7 citations , August 2009 in “Applied Mathematics and Mechanics-English Edition”

This study demonstrates that (9+2) topological patterns derived from fractal fiber sets exist, with nine total patterns and only two being independent or fundamental.

research Effect of Needle Geometry on Insertion Force of Different Hair Implanters

January 2021 in “Advanced Biomedical Engineering”

This study found that hair implant needles with longer point lengths and smaller bevel angles required less total work for insertion, which corresponded with surgeons' perceptions of insertion force differences.

community Hair regrowth without drugs (99% natural) 25M

528 upvotes 3 months ago

A user shared their experience with hair regrowth using supplements like NAC and DIM, and briefly using minoxidil with microneedling. They reported some improvement in hair density, but the community questioned the effectiveness compared to traditional treatments like finasteride.

community 3 days after a hair transplant

2107 upvotes 1 year ago

A user humorously shared their appearance three days after a hair transplant, sparking jokes and memes about their head shape. They remained positive, acknowledging the swelling and hoping for improvement.

community Cbum's hair transplant looks absolutely terrible

979 upvotes 1 year ago

A bodybuilder's hair transplant appears unnatural with a straight hairline and low density, possibly worsened by not using finasteride. The Turkish clinic is criticized for poor design, and the transplant may have been free for promotion.

community One year on minoxidil, one month on finasteride

127 upvotes 8 months ago

A 25-year-old has been using topical minoxidil for one year and oral finasteride for one month to combat hair loss, with no side effects from finasteride so far. The user reports that minoxidil has helped maintain their hair, with some improvement in temple volume, and is considering adding dermarolling.

community Why the Brain Resists Updating Your Appearance: The Neuroscience Behind “It Happened Overnight”

6 upvotes 7 months ago

The brain resists updating its perception of gradual appearance changes, like hair loss, due to its preference for stability and reliance on an internal model. This delay in perception can make changes feel sudden once the brain finally updates its model.

learn Hair Fibers

cosmetic product that temporarily makes hair appear thicker

Do hair fibers really make thinning hair look fuller, or is it just an illusion? Hair fibers create an optical illusion of fullness but do not actually thicken hair.
How do you apply hair fibers correctly so they stay in place all day? Apply hair fibers to clean, dry hair and use a setting spray for better hold.
Can hair fibers be used along with medical treatments like minoxidil or finasteride? Yes, hair fibers can be used with minoxidil or finasteride without any chemical interaction.

learn Hair Transplant

Hair transplantation moves DHT-resistant follicles from a donor area (back and sides of the scalp) into thinning or bald areas. The transplanted hair is generally permanent, though surrounding native hair can keep thinning.
