research Quantifying variation in human scalp hair fiber shape and pigmentation

32 citations , March 2016 in “American Journal of Physical Anthropology”

This study suggests that chemical methods can reveal subtle differences in scalp hair color variability across populations and emphasizes the need for enhanced understanding of hair fiber curvature.

research The Genomic Variation in Textured Hair: Implications in Developing a Holistic Hair Care Routine

October 2024 in “Cosmetics”

This review highlights the lack of research on Afro-textured hair, emphasizing the need for better understanding of its genetic traits and molecular structure to develop more effective hair care solutions.

Seasonal Variation in Hair Follicle Activity and Fiber Growth of Both Male and Female Merghoz Goats in Western Iran

research Seasonal variation in hair follicle activity and fibre growth of both male and female Merghoz goats in Western Iran

5 citations , October 2011 in “Small ruminant research”

This study found that seasonal changes significantly affected hair follicle activity and fibre growth in Merghoz goats, with variations seen in feed intake and growth patterns across different seasons.

research Electrophoretic variation of hair proteins.

2 citations , November 1996 in “PubMed”

In this study, a "frequent profile" of hair proteins was observed in 180 of 182 individuals, showing consistent electrophoretic bands characteristic of keratins, with rare deviations in two samples.

research Investigating the origins of nanostructural variations in differential ethnic hair types using X‐ray scattering techniques

15 citations , May 2013 in “International Journal of Cosmetic Science”

This study found that while ethnic hair types share a common fibrous keratin structure, variations in keratin-associated proteins and lipids may lead to different macroscopic hair characteristics.

community Genetic variations associated with response to Dutasteride. Why is it never mentioned?

in Research/Science 26 upvotes 1 year ago

Genetic variations influence how people respond to dutasteride for hair loss, with some benefiting more from finasteride. Dutasteride is effective for most, but genetic differences may cause it to be less effective for some.

community Noticeable shed after vacation and break in my regimen

in Update 2 upvotes 11 months ago

The user experienced significant hair shedding after pausing their hair care regimen, which included finasteride, micro-needling, Nizoral shampoo, vitamin D, essential oils, melatonin, caffeine, exercise, and protein intake. They are concerned if the shedding is due to the break in their routine or a normal phase of finasteride use.

community How long does hair actually take to recover from a shed?

in Finasteride/Dutasteride 4 upvotes 1 month ago

Hair regrowth after shedding typically takes 4-6 months, with variations depending on individual hair growth cycles. Finasteride can cause shedding, but new hair will grow back at its natural rate.

community Man i thought progress was linear but im back to shedding right before a vacation.

in Update 10 upvotes 1 year ago

The user is experiencing hair shedding despite using finasteride, minoxidil, and microneedling, and is concerned about the non-linear progress. Other users share similar experiences, suggesting shedding is normal and cyclical, with some recommending less frequent microneedling.

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.

Why do hair transplant costs vary between clinics? Hair transplant costs vary due to surgeon expertise, technique, clinic reputation, and geographic location.

learn Thymosin Beta 4

What role does Thymosin Beta 4 play in scalp biology compared to traditional hair loss treatments? Thymosin Beta 4 may enhance scalp biology but lacks extensive clinical validation compared to traditional treatments.

learn Osteopontin

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

learn Exosomes

Microscopic delivery system that sends growth-promoting signals to hair follicles

learn Metformin

diabetes drug with anti-inflammatory, immunomodulatory, and insulin-sensitizing properties

learn Vascular Endothelial Growth Factor

learn Hair Fibers

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.
