Did you mean Mechanical Stress?

Glossary Mechanical Stress

physical forces exerted on hair or scalp causing damage

Mechanical stress refers to the physical forces exerted on hair strands or the scalp, which can lead to damage or hair loss. This can occur from actions like tight hairstyles, frequent brushing, or the use of harsh hair accessories. For professionals, understanding mechanical stress is crucial for advising patients on hair care practices to prevent traction alopecia and other forms of hair damage.

research Expansion of specialized epidermis induced by hormonal state and mechanical strain

3 citations , February 2015 in “Mechanisms of development”

This study observed that areola formation in mice requires exposure to pregnancy hormones and mechanical strain, beyond individual stimuli like hormonal milieu or strain alone.

research Expansion of specialized epidermis induced by hormonal state and mechanical strain

May 2015 in “PMC”

This study found that areola formation in mice requires a combination of pregnancy hormones and mechanical strain, with individual stimuli causing only modest changes in epidermal proliferation and connective tissue remodeling.

research Efeito da radiação ultravioleta na cor, na perda proteica e nas propriedades mecanicas do cabelo

1 citations , February 2003

This study found that UVB radiation primarily causes hair protein loss, while UVA radiation mainly contributes to hair color changes, with no significant differences in mechanical properties observed between photooxidized and non-irradiated hair.

research Strain and Strain Recovery of Human Hair from the Nano- to the Macroscale

November 2023 in “Life”

This study found that human hair exhibits significant deformation in its intermediate filaments under strain, with recovery taking about 1000 minutes, suggesting a self-healing period post-mechanical stress. Additionally, cuticle scales deform much less than the cortex, and the Poisson ratio aligns with soft matter properties.

research Understanding Curly Hair Mechanics: Fiber Strength

8 citations , July 2019 in “The journal of investigative dermatology/Journal of investigative dermatology”

This study found that the tensile strength of curly hair is influenced by two main components, with springiness (toe region) contributing significantly, unlike in noncurly hair where it is negligible.

community Hair loss research focused on chemistry for decades because we misunderstood the mechanics of growth.

51 upvotes 7 months ago

Hair growth relies on mechanical forces, not just chemicals, with tissue acting like a motor. Minoxidil and finasteride help, but maintaining tissue elasticity and addressing mechanical issues are essential.

community The Real Reason For Hair Loss?

8 months ago

Hair loss is linked to scalp fibrosis and tension, which result from chronic mechanical stress and androgenic signaling. Treatments include blocking androgens with finasteride, promoting hair growth with topical minoxidil, and improving scalp mobility through exercises.

community My hair stopped shedding as much in the shower and I traced it back to one change

4 months ago

Switching from a clarifying shampoo to a gentler rosemary biotin shampoo bar reduced hair shedding. Aggressive cleansers can cause scalp inflammation, contributing to hair loss.

community KX-826 and RU58841: do topical anti-androgens work?

10 upvotes 2 weeks ago

KX-826 and RU58841 are topical anti-androgens discussed for hair loss prevention, with KX-826 showing promise in trials and RU58841 having mixed anecdotal results. Users report combining these with treatments like minoxidil, finasteride, and dutasteride, with varying success and concerns about side effects.

community Occipitalis Muscle Tension Theory

13 upvotes 7 months ago

Scalp tension from the occipitalis muscle is theorized to contribute to hair loss, but most believe DHT and genetics are the main causes. Treatments like finasteride and minoxidil are considered more effective than addressing scalp tension.
